PSA

Mercury analysers are now an essential tool for all analytical laboratories as mercury which is extremely toxic to humans is a major contaminant throughout our environment. The PSA 10.025 Millennium Merlin mercury analyser is designed specifically for the analysis of mercury in all types of samples. The analyser combines the advantages of vapour generation techniques which removes most chemical interferences with the sensitivity and selectivity of atomic fluorescence spectrometry which allows mercury analysis down to sub ppt detection limits with 107x linearity.

Applications

Technical Specifications

The PSA 10.035 Millennium Merlin 1631 was developed for the determination of mercury at low levels and specifically to be compliant with EPA Method 1631 for mercury in drinking water. The instrument is essentially the same as the PSA 10.025 Millennium Merlin but with the inclusion of a gold trap prior to the detection step. The system uses continuous flow vapour generation, but the generated mercury vapour is passed over a gold trap where the mercury is preconcentrated.

Technical Specifications

The 10.045 Millennium Merlin Cold Vapor AAS System was developed to be compliant with EPA Cold Vapor methods stipulating the use of atomic absorption for the determination of mercury at low levels.
