Dosimeter Holders:
Install the holder system according GEX Doc# 100-168 - GENESYS 30 Dosimeter Holder System. Once the holder system is
properly installed, the dosimeters can be inserted and the sample compartment lid of the GENESYS 30 should remain open
during measurements. The lid should be closed when not in use or during Performance Verification (P.V).
INSTRUMENT CALIBRATION / PERFORMANCE VERIFICATION (P.V.)
The instrument is not provided by Thermo Scientific with a Calibration Certificate because of a change in technical terminology.
The instrument can be tuned so that it performs within a given list of specifications but technically cannot be ‘calibrated’.
Therefore, it is tested at the factory for proper performance, but it is the user’s responsibility to ultimatiley verify the
instrument performance after the instrument is installed at the user’s site.
The term ‘Performance Verification’ replaces the older term ‘Calibration Verification’ but the intent of either is the same; to
determine if the instrument is performing within the manufacturer specifications. See GEX Doc# 100-270 - GENESYS 30
Performance Verification for complete details.
STAND-ALONE MEASUREMENTS
The instrument can be used when disconnected from a PC to make measurements. For most users, this will never be a
necessity, but some users may find it useful despite the limitations from using the instrument in this manner. For more
information on making fixed or scanning measurements, see the Thermo Scientific GENESYS 30 User Guide.
Fixed Wavelength Measurements:
The protocol below must be followed to make fixed wavelength dosimeter measurements:
1. Insert the appropriate dosimeter holder according to GEX Doc #100-168, GENESYS 30 Dosimeter Holder System -
Product Specifications and Usage (PSU).
2. From the instrument home screen, highlight “Fixed” and press the enter () button. See Figure 3 below.
FIGURE 3
3. Input the correct wavelength setting for the dosimeter type you are measuring and select “Done”. See Figure 4
below.

4. Ensure the dosimeter holder is empty, then zero the instrument by pressing the yellow “0.00” button.
5. After the instrument is zeroed, insert a dosimeter to be measured and select the green diamond-shaped button. The
measurement will be captured on the screen. See Figure 5 below. Measurement time for each dosimeter is less than
1 second.
FIGURE 5
6. After the measurement is recorded, remove the dosimeter and insert the next sample to be measured. Repeat step 5
above for all dosimeters.
NOTE:Only 10 consecutive measurements may be taken. If more than 10 measurements are needed, you must save or
discard the data before proceeding. The recorded measurements may be output to an external USB drive in the
form of .CSV files.
Scanning Measurements:
Sometimes a series of measurements over a range of wavelengths is the objective, in particular for qualification and
performance verification activities, and this can be accomplished using the Scan feature of the GENESYS 30.
Follow the procedure below to determine the peak wavelength of an irradiated film dosimeter or reference standard
(modify the procedure as necessary for other similar types of measurements):
1. On the home screen of the GENESYS 30 navigate to the scan icon.
2. Set the Scan Range (X-axis limits) at 500 – 600 nm in the absorbance mode by navigating using the arrow keys and
typing in the values for the lower and upper limits.
3. Zero the GENESYS 30 with the intended dosimeter holder installed with no sample using the yellow 0.00 button.
4. When the zeroing process is complete insert a B3 dosimeter into the dosimeter holder.
5. Press the green Play (measure) button on the instrument keypad.
6. The resulting graph will display. Using the arrow keys move the vertical line.
7. The resulting graph forms a peak, move the line until you reach the peak absorbance value. Record the wavelength
associated with this value; this is the peak absorbance wavelength.
