575 Series Passive Sampler for Methanol
Overcomes Limitations of Active Methods

SKC VOC Chek 575 for Methanol
The miniature VOC Chek 575 for Methanol Sampler collects methanol vapors in air without the use of a pump. Vapors simply diffuse from the atmosphere into the sampler at a 1.2 ml/min fixed sampling rate. SKC has validated the sampling rate of the VOC Chek 575 Methanol Sampler along with other critical sampling parameters to meet OSHA/ASTM/ANSI requirements.

 

 

Full-shift Sampling with only ONE sampler

The SKC Methanol Passive Sampler collects methanol for up to an 8-hour work shift with superior efficiency. The Methanol Passive Sampler overcomes the short sample times and sample migration concerns of active methods. These samplers are ideal for use in chemical, fuel, wastewater, and hydraulic fracking industries.

Using a VOC Chek Passive Sampler is easy as 1, 2, 3!

VOC Chek 575 Series Passive Samplers
Validated to NIOSH Protocol ¹

Validation
Passive sampling is quite different from active sampling with sorbent tubes. With this fact in mind, NIOSH established validation protocols for evaluating the performance of passive samplers. ¹   Protocol validation was developed so that manufacturers could produce passive samplers that reliably assess airborne levels.

For compliance sampling, it is recommended that only passive samplers with full or bi-level validation be used. Passive samplers with lower levels of validation may be used only if verified by validated sorbent sample tube methods.
