Overview
The SYP fluid sampler is an advanced automated tool capable of taking up to 58 liquid
samples continuously or at a configurable intervals and can run for more than a year on a
single set of AA batteries.
The sampler injects sample fluids to sealed vials via peristaltic pump or gravity. Sample
collection is fully configurable and can be triggered via timer, sensor data, or flow rate (in
gravity mode only). By default SYP will rinse componentry between samples to avoid cross
contamination. Full samples are timestamped.
The device is carefully constructed in modular form using quality stainless fasteners, custom
3D-printed components and a transparent acrylic case with carry handles for convenience.
SYP is the perfect companion for scientists at universities, research institutes, regional
authorities or monitoring agencies.

Operation
SYP features a fully configurable sampling regime including two means of collection and 3
sampling modes (explained below). All modes support a fully configurable purge / rinse cycle
between samples.
Set up and use is described in following sections.
Sample method: Gravity & peristaltic pump
Gravity mode was designed for collecting fluid drips falling from a height. It requires a funnel
or reservoir be set up to collect the liquid, which flows into the machine by gravity alone
(without any mechanical support). Gravity mode uses full vial detection to ensure consistent
sample volume and log when samples are completed.
Gravity mode supports continuous, timed or delayed start modes (explained in detail below).
Pump mode was designed for sampling surface or ground water. Here a peristaltic pump
moves fluid from a reservoir into vials at user-defined intervals. The pump runs for a pre-
determined time for each sample to ensure consistent volume, which is safe-checked by the
full vial detection feature.
Pump mode supports timed or delayed start modes but not continuous mode.
Sample mode: Continuous, timed, delayed start
Timed is the standard mode of operation. A schedule is set by the user dicating sample
interval from 1 to 65,000 hours. By default the system will purge before a sample is taken.
Delayed start mode uses either a user-defined timer or sensor data (air pressure, humidity,
temperature) to trigger sample collection. Once the user-defined threshold is met, the device
continues sampling according to user-defined settings.
Continuous mode provides an option for a flow-based sampling regime. Water is fed into the
system and directly into vials. When the system detects a vial is full, it automatically
timestamps sample completion and immediately begins the next sample. By analysing time
stamps at each sample, flow rate can be inferred.
Continuous mode only works while using gravity as the means of collection.
When setting up the device in gravity mode, ensure there is sufficient hydraulic head
to drive flow to vials by gravity alone. Kinks or dips in tubing will cause operating
issues or missed samples.
Pump mode can set up with a funnel or reservoir in tight or cramped settings where
flow to vials by gravity alone is unreliable.

Connect to SYP:
Connect to the SYP fluid sampler using a Wi-Fi enabled device, such as a smart phone or
laptop with web browser (we recommend Google Chrome). The steps below apply to
Android or iPhone smart phones or a Windows PC.
Wi-Fi
Android OS Phones
1. Swipe down from the top of the screen.
2. Touch and hold Wi-Fi .
3. Turn on Use Wi-Fi.
4. Tap the “SYP” network in the list.
Apple iOS Phones
1. Go to Settings.
2. Click on Wi-Fi (Make Sure it is “On”).
3. Choose the “SYP” to connect.
Windows PC
1. Make sure your PC has Wi-Fi available.
2. Click the icon below (or similar), usually found in the tray in the bottom right-hand corner:
3. This will show you the Wi-Fi options. Click on “SYP” to connect.
When you connect to the Auto Sampler, your device may ask if you want to “keep the
connection” as no internet will be available. Click “Keep Connection” to connect to the
Auto Sampler.

P6
Load the SYP interface
There are two ways to load the SYP interface:
1. Scan the QR code using your phone’s camera. This works on newer versions of Android and iOS.
Figure 2
2. Open your web browser (Google Chrome is recommended), and type in 192.168.4.1 into your search
bar.
While connected to SYP you won’t be able to connect to the internet, as the SYP
sampler itself isn’t connected to the internet.

Configuration and use
Status page

Figure 1: Ready to start sampling (1). Figure 2, Waiting for a delayed start (Starting
at Sample 25)
This page shows information about the current status of the SYP fluid sampler and a history
of the samples taken. It also provides environmental information to assist in the setup. This
page also allows the user to start at a specific sample, reset, stop, resume, skip samples,
and refresh data.
How to start
Before starting the sampler, ensure the settings are set correctly on the Settings page. If
you want to start at a specific sample, enter the sample number in the Start Sample field
before pressing Start.
To start SYP, press the Start button. The device will enter the sampling state where it will
start sampling immediately or sit idle waiting for a start trigger depending on the setup (see
Settings).
Once the Auto Sampler has started, the available buttons will change and the machine state
will update when it begins to run. Once the start button is clicked the Auto Sampler will also
create a new Sample file, where all the sample data for that run will be stored.

P8
Reset
The reset button will cause the sample process to stop, clear the sample count, go back to
purge and will wait for the start button to be pressed again.
Skip
This allows the user to move past samples if required. Multiple samples can be skipped by
pressing the button multiple times in quick succession.
Note: The table will rotate at a higher speed if it must travel further to reach the new sample
position.
Stop
This will stop the sampling process and change the Auto Sampler into an idle state. The
needle block will move to the purge location regardless of where it currently is.
Note: While stopped, the Next Sample Time won’t be updated.
Resume
This will move the Auto Sampler back into the sampling state. The needle block will move
back to the sample that it was stopped at.
Note: When resumed the Next Sample Time won’t be updated.
Refresh
When pressed all sensor data and battery voltage will be updated immediately.
Graph
The graph shows the data from the current sample file, but only loads the data when the
page refreshes. To hide or show specific data, just click on the data set in the legend
(Figures 1 & 2).
Menu
Click this button to navigate to the menu page.
