Section 1: Warnings ⚠
The complete contents of this manual must be reviewed to ensure that the product is used safely. When
integrating the EXTRACTION FINDER, the total extraction system design must be considered to ensure safe,
trouble-free performance. Function, material compatibility, adequate ratings, proper installation,
operation, and maintenance are the responsibilities of the system designer and user. Below are Arometrix’s
warnings about safe operating conditions for the EXTRACTION FINDER:
1. Ensure the system and installation conform to all applicable laws and ordinances, including Fire
Marshall code certifications.
2. Ensure all supporting electronics are installed in a compliant matter.
3. Ensure all connections are properly installed and specifications are appropriate.
4. If you have any indications of malfunction, return to the manufacturer immediately by emailing
bra[email protected].
5. Tampering with this equipment is prohibited, and will result in a void of warranty.
6. Never look directly into the light source.
7. MISUSE MAY CAUSE SEVERE INJURY OR DEATH. Proper care should be taken when setting up and
operating this equipment.
Section 2: Overview
What the EXTRACTION FINDER is:
The EXTRACTION FINDER is Arometrix’s real-time molecular monitoring system for botanical extraction.
The technology used induced fluorescence to detect the presence and track the levels of molecules, such
as Cannabinoids, Chlorophyll, and Lipids in-line. This helps operators optimize extraction process efficiency.
What the EXTRACTION FINDER is not:
The EXTRACTION FINDER is not a quantitative measure. It provides qualitative process information that
directly tracks the relative concentration of Cannabinoids. It is Arometrix’s goal to amass enough spectral
data from the EXTRACTION FINDER to eventually be able to determine quantitative purity in the future.
The EXTRACTION FINDER cannot replace good laboratory practice and experience. The EXTRACTION
FINDER’s data, in combination with good lab practice, will help technicians further perfect their craft.
Section 3: Fundamentals
The Arometrix EXTRACTION FINDER is composed of three key components: the Digital Display and the
Ultra-Sensitive Sensor, which is housed inside of the Sensor Housing (aka Extraction Adapter).
Arometrix Digital Display:The display contains the “brains” of the system. This 7 inch LCD TFT display
consists of a compute module that creates a visualization for the user where both flow and relative
potency are deduced. The display has a pole-mounting bracket installed in the back of it so it can easily be
mounted to a lab pole. It also includes an extended 30’ sensor cable and 10’ power supply extension to
move the display outside of the C1D1/C1D2 environment. Note: This unit is intended for laboratory use.
Care should be taken not to spill anything on it, as it is not waterproof.

Arometrix Ultra-Sensitive Sensor:The sensor contains the “eyes” of the system”. The sensor, attached to
size 34 high pressure glass inside the Extraction Adapter, connects and transmits to the digital display. The
ultra-sensitive sensor has a new filter that allows it to be more sensitive than Arometrix’s original sensor.
Arometrix Sensor Housing (aka Extraction Adapter):The sensor housing houses the ultra-sensitive sensor
and is installed in-line.
Section 4: Unpacking & Inspecting
After the instrument is received, it should be carefully
unpacked and inspected for damage during shipment
and to confirm that all components are present.
Each EXTRACTION FINDER comes with:
●Digital Display + pole-mounting screw
○Color of sticker will be black or green
●Sensor Housing with Ultra-Sensitive Sensor
○Sensor pre-installed inside of housing
●30’ Sensor Cable, USB
●International Power Supply
●10’ Power Supply Extension
Section 5: Installation & Software Quick Start
The equipment should be in a clean, dry environment for the best results.
Installation of the Sensor Housing involves the following steps (illustrated on our Quick Start Guide):
1. Mount the Sensor Housing securely onto the extractor's 1.5” or 2” sanitary end clamps.
Arometrix, Inc. [e-mail] arometrix.com/resources

5
2. On the bottom-end of the Sensor Housing, connect a 1.5” Sanitary Flange to Hose Adapter (or
NPT adapter or another appropriate connection) for incoming flow.
3. On the top-end of the Sensor Housing, connect a second 1.5” Sanitary Flange to Hose Adapter for
outgoing flow.
4. Install a bypass, valved bleedport and pressure gauge for optimal safety and performance.
5. Best Practice: Set up an extraction adapter bypass (that can be quickly actuated through 3 way
valves), a vent, and a pressure gauge.
6. Warning: Ensure all connections are properly installed. Ensure the system and installation conform
to all applicable laws and ordinances.
Installation of the Display and wiring involves the following steps (illustrated on our Quick Start Guide):
1. Install the Extraction Finder display(s) outside of the C1D1-designated area. Use the supplied AC
adapter and 10’ power supply extension to power your display. This adapter provides clean short
protected power to protect and ensure the accuracy of the internal circuitry.
2. Connect the other end of the sensor cable to the bottom of the display. The display will take a few
seconds to turn. You will see splash screens, followed by the interface screen. Give it ~2-5 minutes
to boot up.
3. You can mount the display to a lab pole using the provided pole-mounting screw; the back of the
display has a pole-mounting bracket pre-installed. Alternatively, it can be placed on a desktop by
placing the unit in a separate tablet stand.
4. In the Settings section on the display’s UI:
a. Set Auto Integration by checking the AID (Auto) checkbox
Arometrix, Inc. [e-mail] arometrix.com/resources

b. Set Scans to Average: 5
c. Ensure that the Device Status and Server Status indicator on the bottom left-hand side of
the display are green – If not, make sure the cords are properly connected.
d. Ensure that the “Light On/Light Off” toggle button is turned on. The light above it should
be green.
e. To set ranges, go to Settings, select “Wavelength Settings” to track specific molecules. For
extraction, we recommend setting:
i. Region 1: Delta-9 (or CBD Indicator)
ii. Region 2: Lipids
iii. Region 3: Chlorophyll
iv. Pro-tip: Once you return back to the homescreen, check each region’s checkbox for
easier tracking during the process.
5. Record on (optional) at the start of the run: Toggle the Record button to On. Ensure the Record
indicator is green.
6. Once the Extraction Finder system is safely in operation, prepare extraction as you typically would.
Arometrix, Inc. [e-mail] arometrix.com/resources

7. Monitor molecular signals during your extraction process.
a. Observe no signal or noisy signal on XF from reverberations during initial startup.
b. Identify XF signal spiking then dropping after initial fluid flow.
c. Identify XF signal equilibrate during full flow.
d. Observe Delta-9, Lipid, and Chlorophyll levels on the Display. Switch views by tapping the
“display” button. Use the changes in relative potency levels in order to inform your
extraction process decisions.
8. Record off (optional) after the run is finished: Toggle the Record button to Off to save XF data.
Arometrix, Inc. [e-mail] arometrix.com/resources

Ensure the Record indicator is red. Install USB thumb drive (ensure that no files are on the USB
stick first). Finally, press the Transfer function.
9. Pro-tip: Once done, upload logged run data file(s) into our DAB (Data Analysis Breakdown) App.
Section 6: Understanding the Interface
After installation, the system is ready for immediate operation.
Different Viewing Options
There are currently two viewing options: the Spectrum view and the Wavelength view. These display
options can be toggled between each other by tapping the “display” button (located in the top-left corner).
Spectrum View (Spectrograph) - Instantaneous Tracking
What it does:This is an instantaneous representation of the current spectral state. It displays the current
background/ambient light corrected spectral measurement.
Arometrix, Inc. [e-mail] arometrix.com/resources

9
Important Note: The peak at 360-390nm is an internal excitation/reference peak (not a process indicator);
tap the small circle on the top-left corner of the graph if you wish to remove this peak.
Understanding the Graph (X-Y Axis)
●X-axis = Wavelength (nm):The location of where the line shoots up (or fluoresces) indicates the
molecule(s) passing through; different molecules have different wavelength regions
●Y-axis = Intensity (counts): The height of this line, in general, indicates how much of that substance
is present at that moment relative to earlier.
Wavelength View - Time Tracking
What it does: Displays and tracks the interpreted values from your measurement. This plot reduces the
raw data and shows you the “highlights” of the run. This view is especially useful for seeing how molecular
levels changed over time. Arometrix recommends that Extraction Finder users prioritize this view.
Understanding the Graph (X-Y Axis)
●X-axis = Time (HH:MM:SS):As opposed to the Spectrum view, this tracks molecular levels for
pre-set ranges as a function of time.
●Y-axis = Intensity (AU): The height of this line indicates how much of that substance is present at
that moment relative to earlier. (Note: These are AU as in Arbitrary Units; this is not quantification
of potency.)

These correspond with the Region 1, Region 2, and Region 3 that are shown on the plots. When you press
one of these, you will see a Wavelength range. These will come preset with manufacturer’s defaults;
however, you can edit the From and To how you see fit. See below.
Click “Default” to return back to manufacturer default. Next to the “Default” button, you will see a
molecule dropdown. When you press the Molecule Indicator dropdown, you will see different molecule
tracking options. You can select any of them, or set your own “Custom” molecule and region. See below.
Set Integration Time
This is meant to enable “AID (Auto)” by clicking the checkbox in the bottom-left corner of the screen. Auto
integration ensures that the signal from the spectrometer is maximized.
Set Scans to Average
This sets how many optical readings the sensor takes before plotting and displaying a result. More
readings that are averaged imply less noise, but less information. Arometrix recommends that you select 5.
Clock Settings
This should be set during initial acquisition. Set the Date Settings and the Time Settings. Then, Submit.
System Data
This will display “Bytes Available”, “Bytes Used”, and “Bytes Total”. It will also show you % memory used,
and give you an option to “Clear Data”.

Section 7: Application Note - Solvent Saturation
Below is a real graph of a full extraction run using the Extraction Finder in Wavelength View. The
Extraction Finder tracked Chlorophyll (blue) and Cannabinoid (orange) signals. Note: The Chlorophyll/
Cannabinoid ratio (grey) signal is for the purposes of this manual only.
Cryo-Ethanol Extraction Run - Recirculation - Extraction Finder Logged Run Data
A. Filling System -The extractor was being filled with ethanol
a. No flow over sensor; no signal
B. Agitation Then Soak - The extractor was agitated then went through a soak cycle
a. No flow over sensor; initial signal noise due to mechanical vibrations
C. Flow Started/Equilibrating Flow - The flow for recirculation began
a. Full flow over sensor; signal spikes then drops after initial fluid flow
D. Recirculating - Extractor recirculated ethanol over system
a. Full flow over sensor; signal increases/decreases as Cannabinoid concentration equilibrates
and becomes homogeneous in ethanol
b. End point determined by both Cannabinoid and Chlorophyll signals (and their ratio)
becoming stable/unchanging
E. Emptying System using N2Gas - Endpoint detected (solvent saturated)
a. Extractor being emptied with nitrogen gas and system no longer chilled; Signal of both
Cannabinoids and Chlorophyll decrease
F. Emptying Residual Alcohol from Extractor - Extractor reservoir emptied
a. Decrease in both Cannabinoid and Chlorophyll signals; increase in ratio of Chlorophyll to
Cannabinoid from system heating (ethanol preferentially extracting Chlorophyll in
reservoir)

Section 8: Issues
1) If the signal is an abnormally low signal, a few things should be checked:
a. Ensure that the EXTRACTION FINDER system is properly installed.
b. Ensure that the integration time is set correctly by using the AID (Auto Integration) AUTO in
Settings. The checkbox should be checked off.
c. Ensure that the Scans to Average is set to 5.
d. If none of the above seem to be the origin of the problem, please take a photo of both
your spectrum plot and your wavelength plot, then email [e-mail].
2) If the signal looks sporadic and very abnormal, a few things should be checked:
a. Is there turbulent flow in the Extraction Adapter? Turbulent flow is not ideal. For the best
signal, ensure consistent, full flow. The addition of a small sight glass somewhere on top of
the Extraction Adapter might help you ensure this.
b. If the pressure is still changing quickly, wait for the pressure to become more constant.
c. Ensure that the integration time is set correctly by using the AID AUTO.
d. Increase the scans to average:
i. This should not be set significantly higher than 5 - keep the value below 15
e. Ensure that the Extraction Adapter is not in a location with a high amount of vibration
f. Ensure that the Extraction Adapter is not in a location monitoring the vapor phase
g. If none of the above are the problem – ensure that liquid is still flowing
h. If none of the above seem to be the origin of the problem, please take a photo of both
your spectrum plot and your wavelength plot and contact customer service by emailing
[e-mail] or submitting the Support Request form on our website
3) If the system is not detecting the sensor (bottom left light on panel is red or yellow)
a. If the system was turned on, give the system up to 5 minutes, it may detect
b. Ensure that all cables are connected securely – especially the cable connecting the display
unit to the sensor
i. It may be easier just to disconnect and reconnect the cables from the display unit
and the sensor unit
c. Try identifying and using a new source of power to power the EXTRACTION FINDER display.
d. If none of the above seem to be the origin of the problem, please take a photo of both
your spectrum plot and your wavelength plot and email [e-mail].
