ISCO GLS - Collecting Grab Samples

Section 3 Operation
3-11
• Bottle full - Remaining samples were not
collected because the GLS detected a full
bottle.
3.6 Grab Samples
Grab samples let you take a single sample on
demand, collecting the sample in an external
container. You can collect a grab sample while
the GLS is running a program, paused, or in
standby.
To collect a grab sample:
1. Press the Grab Sample button.
2. The GLS asks how much liquid to collect.
Using the number-entry buttons, enter the
desired volume (in ml). Press the Enter
button to continue.
3. The GLS waits for you to prepare to collect a
grab sample. Pull the lower pump tube from
the bulkhead fitting. Hold the end of the
tube over a container. Press the Enter
button when you are ready.
4. The GLS goes through a complete sample
collection cycle and deposits the requested
amount of liquid in the container.
5. Return the pump tube to the bulkhead
fitting.
Note
If a grab sample is taken while a program is running, it is
not counted as part of the number of samples.
