New article in LCGC: The Column – Extending analyte ranges using multi-bed sorbent tubes
Tuesday, 7 April 2015 at 2:44:PM
The March 2015 edition of LCGC: The Column features an
article by Caroline Widdowson and David Barden that compares the performance of
multi-bed and single-bed sorbent tubes for indoor air quality and material
The article summarises two peer-reviewed studies that demonstrate
how multi-bed tubes give improved recovery of very volatile compounds compared
to single-bed Tenax® tubes, without compromising the recovery or stability of
heavier target analytes.
Widdowson and Barden say that although such multi-bed tubes are
popular in environmental analysis, methods for material emissions testing have
traditionally targeted relatively narrow analyte ranges. However, this is now
changing, with a recent revision of a key international standard method
including the option to use multi-bed sorbent tubes.
