| Hydra-C is a direct combustion mercury analyzer that is available with cold vapor atomic absorption (CVAA). Hydra-C works by thermally decomposing the sample to release mercury vapor instead of the chemical reduction step used in most liquid based analyzers. Solid and liquid samples in all kinds of matrices can be loaded onto Hydra-C’s autosampler and analyzed without acid digestion prior to analysis. The chemical decomposition process does not require the conversion of mercury to mercuric ions so lengthy sample pretreatments are unnecessary. Because chemical reduction is not used, there is no need for reagents such as strong acids, oxidizers and reductants. There is also no hazardous waste to be disposed of at the end of analysis. As a result, the Hydra-C reduces both analysis time and cost.
The Hydra-C employs the advanced, time-tested optical designs of our earlier continuous flow analyzers coupled with gold amalgamation purge and trap pre-concentration to achieve high sensitivity and low noise. The Hydra-C provides Windows™ 2000 programming and is fully automated with computer control of all instrument parameters and functions. An on-line balance is available for electronic sample weight input.
