Data System Control
The Online Sampler for Purge & Trap is designed for applications where a single water
stream needs to be measured automatically and repeatedly by purge & trap. The Online
Sampler automatically fills and empties the test tube purge vessel of the
with a precisely metered 5mL volume of water. This is useful when monitoring
a single stream of contaminated groundwater, or a waste water stream.
A valve with a 5mL loop, special plumbing, and a custom purge head make up the Online Sampler. The stream to
be monitored is plumbed to the Online Sampler and a 10-100mL/minute flow is established to continuously flush the loop
with fresh sample. When used with an SRI Purge & Trap GC, the
controls the sampler transfer
the loop contents into the purge vessel of the purge & trap concentrator. When the purge is complete, the purge vessel
is emptied to waste. The valve may be optionally configured with a second loop so that an internal standard can be
injected along with the water sample.
