Description

The analytical system for the determination of Hg species consists of a Perkin Elmer HS 40 XL TurboMatrix headspace sampler coupled to an perkin Elmer Clarus 500 gas chromatograph through a heated fused silica transfer line. The outlet of the GC is coupled to an atomic fluorescence detector (TEKRAN 2500 CVAFS Mercury detector) via a pyrolytic column.

The Perkin Elmer HS 40 XL TurboMatrix headspace sampler consists of a sample carousel that can contain 40 samples and an oven that can thermostat up to 12 samples simultaneously, maximizing sample throughput. The advantage of the pneumatic, pressure-balanced sampling technique is avoiding the use of multi-port valves and gas syringes.

The transfer line is directly connected to the packed GC column (on-column injection). The GC column consists of an 80-cm-long Teflon tube (OD 1/4", ID 3 mm) filled with 10% OV3 on Chromosorb W-AW DMSC (60/80 mesh) (Altech). The headspace vials are 22-ml Pyrex glass vials closed with Teflon-coated butyl rubber septa and Al caps.
