DSP - Diffusive Sorbent Pens™

Entech Sorbent Pens™ represent in advancement passive ’diffusive’ sampling, incorporating many subtle but critical engineering design elements that ensure quantitative recovery, reproducibility, and cost  effective long term use. The result of decades of research into volatile chemical sampling and analysis has resulted in a sampler so accurate and reproducible that the data is almost unbelievable!

ASP - Active Sorbent Pens™

Active sampling significantly accelerates the sampling process compared to passive diffusive sampling, which typically operates at around 0.5cc/min. By utilizing a vacuum source to draw air through the sampler and measuring the total volume of air drawn through the ASP Pens, active sampling rates can be increased to several cc’s per minute.
