4.11 Grab Samples Grab samples let you take a single sample on demand, collecting
the sample in an external container (Figure4-4). Keep in mind:
When the sampler delivers a grab sample, it runs through a com-
plete sampling cycle, using the current settings for volume and
for line rinses or retries. If it is a two-part program, the sampler
uses the settings for part A.
To take a grab sample while the sampler is running a program,
you must interrupt the program by pressing the Stop key.
Restart the program by running it again.
To take a grab sampl e:
1. Disconnect the pump tube from the bulkhead fitting.
2. Place the end of the tube over a collection container.
3. Follow the steps in Taking a Grab Sample at left.
4. Reconnect the pump tube to the bulkhead fitting.
