Grab Samples
Grab samples let you take a single sample on demand, collecting
the sample in an external container (
Figure 12
). It is a simple pro-
cedure, but there are two things to keep in mind:
• When the sampler delivers a grab sample, it runs through a
complete sampling cycle, using the current settings for line
rinses or retries.
• To take a grab sample while the sampler is running a program,
you must interrupt the program. (See Interrupting a Running
Program on page 51.)
To take a grab sample:
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 in the margin.
4. Reconnect the pump tube to the bulkhead fitting.
