The Hydra II AF Mercury Analyzer and Hydra II AF Gold Mercury Analyzer from Teledyne Leeman Labs operate on a technique based on cold vapor atomic fluorescence detection to deliver low detection limits as low as 0.02 ppt with amalgamation, and high sample throughput with as little as 1 minute without amalgamation. These mercury analyzers have a large sample capacity that can hold up to 270 samples and 12 standards, while providing fast measurement speeds to deliver more results with less effort. Designed to meet tough water quality regulations and standards, these mercury analyzers utilize a unique gas liquid separator to remove mercury vapor from the sample and prevent contamination for analysis of difficult samples.
