Monitoring of Siloxanes in Landfill and Digester Gas using Advanced Silonite
Abstract A complete monitoring solution for the measurement of Siloxanes from 10-2500 PPBv in Landfill and Digester Gas is presented. Stainless steel vacuum sampling canisters with a newly improved Silonite ceramic surface improves the storage and recovery of siloxanes out through L5/D6 with demonstrated holding times of at least 2 weeks. Improvements in GCMS sample […]
Entech Air Monitoring Sorbent Pens™
Entech Sorbent Pens™ represent the future of 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!
