Products - Passive Sampling

 

Entech is a leading supplier of canister based sampling equipment, for the collection of volatile compounds and analytical instrumentation for measurement of volatile compounds in the gas phases by GC and GCMS. Our environmental products meet EPA specifications for methods TO1, TO2, TO3, TO12, TO14 and TO15 for VOC sampling analysis.

 

Passive Canister Based Sampling Equipment


 

CS1200E, ES & T
Passive Canister Samplers

 

The CS1200E, ES & T model canister samplers are compatible with the 1/4" connector found on most canisters and give you fill times of up to 7 days in a 6 liter canisters.

 

The CS1200E offers excellent performance for TO 14 and 15 compounds.

 

The CS 1200SE adds the inertness of Silonite for sampling of highly reactive compounds such as formaldehyde and H2S.

 

The CS 1200T is optimized for trace sampling of sub-slab / vapor intrusion compounds Accessories include a direct connect sib slab sampling probe.

 


CS1200 Instructions


TM1100 Digital Timer

 

The TM1100 is a new, low cost, programmable, one week, battery operated digital timer for unattended sampling and can be programmed for multiple sampling periods.


Grab Samplers and
Restricted Samplers

Integrated samples are not always required but just opening the valve on your canister can lead to particulate contamination that will reduce compound recovery and can not be removed by normal cleaning procedures. Entech's Grab Samplers offer a solution for keeping your canisters clean.

 

Entech offers more 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.


IH1200P Personal Sampler

The IH1200P Personal Sampler makes canister based, whole air sampling practical for Personal Monitoring of VOC exposure in Industrial Hygiene applications.

 

Sampling into an evacuated canister eliminates the need for battery powered pumps resulting in more reliable sampling.

 

Analysis of whole air samples can be performed by GCMS for positive analyte identification and for surveying unknown compound exposure.


CS1200P Passive Canister Sampler


(Shown with MiniCan)

The CS1200P Passive Canister Sampler is specifically configured for use with MiniCan Personal Monitoring applications. Testing of the CS1200E at temperatures ranging from 4† C to 40† C showed less than 10% flow rate change. It allows 1,3 or 8 hour sampling periods at a temperature range of -10† C to 45† C. Sapphire flow elements provide extremely stable operation controlling flow down to 0.4 cc/min.

 

It's compact design, including a built in gauge, makes this accessory to the MiniCan ideal for personal monitoring and industrial hygiene applications.


MiniCan Breath Sampler

A new, non invasive procedure for the determination of chemical exposure. Breath sampling gives you sub ppb detection limits without facility and personal demands of urine and blood sampling. So fast and simple, pre and post exposure measurements are now possible.
