Extending the Compatible Analyte Volatility Range for Indoor Air Quality and Material Emissions Testing Using Multi-Bed Sorbent Tubes from Markes

This application note summarizes two important and independent studies aimed at extending the compatible analyte range of tests used to determine chemicals released from materials, and associated indoor air quality measurements. The papers compare the performance of single-bed Tenax® TA tubes to those packed with multiple sorbents, and demonstrate how the latter guarantee improved recovery of very volatile compounds without compromising the recovery or stability of heavier target analytes.
