Rugged, Reliable Semivolatiles Analysis on Rxi-SVOCms Columns.

- Abstract
Semivolatiles analysis is an essential part of environmental testing programmes, yet it can be difficult for laboratories to run methods efficiently because target analyte lists are extensive and contain a diverse array of active compounds. To accurately report semivolatiles, particularly reactive ones, highly selective and inert columns must be used to ensure good chromatography and stable calibrations. In this report, Rxi-SVOCms columns were evaluated for both chromatographic performance and ruggedness. These columns are designed specifically for semivolatiles analysis using new polymer and deactivation chemistries that produce highly inert columns with tightly controlled selectivity for a wide range of analytes (acidic, basic, and neutral). Our testing of 94 semivolatiles from EPA Method 8270 specifically assessed peak shape and resolution for critical compounds, calibration stability, and ruggedness.
