ABSTRACT
USEPA Methods 8270D (semi-volatiles) and 8260C (volatiles) typically require dissimilar chromatographic columns with incompatible maximum temperatures. Historically, laboratories performing these analyses have found it necessary to allocate separate GCMS instrumentation for the two analysis modes, or perform frequent reconfiguration (column changing) to run these methods on a single GCMS unit. Venting the MS system to change analytical columns can be time-consuming and inefficient, however productivity can be improved significantly using the Shimadzu Twin Line MS Kit. With this configuration, two capillary columns are simultaneously installed in the MS, and the user can easily switch between dissimilar applications without venting the mass spectrometer to change the column.
Instrument hardware configuration and operating conditions with two dissimilar capillary columns will be described. Data will be presented which illustrate instrument performance of USEPA Method 8270D when run on a single GCMS with two columns simultaneously installed in the same MS. Data will include chromatography, calibration results, accuracy and precision statistics, and method detection limits (MDLs).
