Calcite Indoor Environment Services Limited and Advanced Chemical Sensors, Inc. proudly introduce ACS Passive (Diffusive) Air Sampling Badges

ACS passive samplers are small "badges" that collect organic vapours without the use of a pump. They are simple, reliable, and economical method for air sampling. Available for personal and area sampling, these small, lightweight samplers include passive badges for formaldehyde, benzene, and toluene, etc. Individual chemicals simply diffuse from the atmosphere into the sampler at a fixed rate.

Advantages of ACS Sampling Badges

Easy to Use

Homeowners and workplace can measure the air quality without employing expensive consulting companies to perform the same duty.

Accuracy

ACS passive samplers meet OSHA and AIHA accuracy and precision requirements for passive samplers.

Economy

No additional equipment needed for air sampling. ACS passive samplers offer full-shift 8-hour sampling; you only need one sampler for a true TWA sample. One sampler means only one analysis.

Efficiency

No need to make multiple worksites visits to change sampling media; full-shift sampling can be done for most compounds
with just ONE sampler.

No multiple layers

No need for expensive backup layers. ACS Passive Samplers have proven results up to 2 times the allowable limit with the presence of interfering compounds.

STEL sampling

ACS passive sampler design permits reliable short-term measurements.

Peace-of-mind

Extensive testing and documented results mean data will stand up in court.

No reverse diffusion

Proper sorbent selection ensures that adsorbed chemicals do not reverse diffuse once trapped onto the collection media.

Superior collection efficiency

ACS sorbents have a larger surface area compared to sorbent wafers or strips, providing higher capacities.
