Grab Samplers and Restricted Samplers - QFS - FQFS - RS - RS-Q/RS-QS

 

Integrated samples are not required in every application. Opening the valve on your canister, however, can potentially lead to particulate contamination that will reduce volatile compound recovery. Entech's Grab Samplers offer a solution for keeping your canisters clean.

 

Entech also offers greater versatility by also providing restricted grab samplers. The addition of a restrictor provides linear sampling rates until the canister is half full. This is a low cost approach to integrate sampling.

QFS

 

Quick Fill Sampler - MiniCan Samplers

An exception to filtering the sample occurs during sampling for semi-volatile compounds. A low cost device designed for STEL or grab sampling with MiniCans provides a clean Silonite coated surface to minimize sample loss. Applications include IAQ/mold investigations, STEL sampling and chemical warfare agents.

Restricted Samplers

 

RS - Nupro Bellows Valve Equipped Canisters

Entech's Restricted Samplers (RS) offer a low cost approach to integrated sampling. Fill rates remain constant until the canister is half full. Sampling can be stopped at this point for a true integrated sample. Sampling can also be allowed to continue if true integration is not required.

 

RS sampler are completely Silonite coated with replaceable Silonite coated filters. This assures the best sample recovery possible while protecting your canister from particulate contamination.

 

RS-Q & RS-QS - Quick Connect Valve MiniCans

RS sampler can be adapted for use with Entech's MiniCans with the addition of a female quick connect. These samplers are available with a stainless steel quick connect - the RS-Q or with a Silonite quick connect - the RS-QS. Both the RS-Q and RS-QS come with a Silonite inlet line and replaceable Silonite filter.
