configured for US EPA Method 8290
一般描述
Developed specifically for use with US EPA Method 8290 - "Polychlorinated Dibenzodioxins (PCDDs) AND Polychlorinated Dibenzofurans (PCDFs) by High-Resolution Gas Chromatography/High-Resolution Mass Spectrometry (HRGC/HRMS)"
The sample clean-up employed in EPA Method 8290 requires a series of hand-packed glass chromatography steps involving: 1) a mult-layer silica gel class column, 2) a sodium sulfate/alumina glass column, and 3) a multi-layer celite 545-activated carbon glass column.
Cat. No. 52732-U can be used in place of the required multi-layer silica gel glass column, and Cat. No. 52733-U can be used in place of the required multi-layer celite 545-activated carbon glass column.
Note that the bed weights packed into these SPE tubes are smaller than what is described in EPA Method 8290. Therefore, to use these SPE tubes, sample volumes need to be scaled down accordingly.
