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 (as does the 10.025 Millennium Merlin), but the generated mercury vapour is passed over a gold trap where the mercury is preconcentrated. After collection for a pre-set time the mercury is then thermally desorbed into the atomic fluorescence detector.
