TheOnlineSampler for Purge& Trap is designed for applicationswhere a singlewater stream needs tobe
measuredautomaticallyand repeatedlybypurge& trap. TheOnlineSampler automaticallyillsandempties
the test tube purge vessel of the SRI Method 5030 Purge & Trapwith a preciselymetered 5mL volume of
water. This isusefulwhenmonitoringasinglestreamof contaminatedgroundwater, or awastewater stream.
A valve with a 5mL loop, special plumbing, and a custom purge head make up the Online Sampler. The
stream to bemonitored is plumbed to the Online Sampler and a 10-100mL/minute low is established to
continuously lush the 5mL loopwith fresh sample.
When usedwith anSRI Purge&TrapGC, thePeakSimpledata system controls the sampler to transfer the
5mL loop contents into thepurge vessel of thepurge& trap.When thepurge is complete, thepurge vessel
is emptied towaste.
The valve may be optionally conigured with a second loop so that an internal standard can be injected
alongwith thewater sample.
