Teledyne Leeman Labs Hydra mercury analyser range

The Teledyne Leeman Labs mercury analysers automate the determination of mercury, freeing time for other laboratory tasks. With capabilities to analyse mercury at levels of 1 ppt and less, analysis times of one minute per sample and a specially designed early warning system to protect against contamination by samples with high mercury levels, the analysers are suitable for any lab wanting accuracy, speed and reliability in mercury analysis.

The preparation system provides unattended sample preparation of up to 88 samples, six calibration standards and seven QC check standards and/or spiked samples in one batch. The digestion procedures are based on EPA approved methodologies.

The models available include: the Hydra II AA, which is a fully automated analyser based on the traditional cold vapour AA technique; the Hydra AF, which is a fully automated cold vapour atomic fluorescence analyser that can detect limits of <1 ppt and a dynamic range in excess of four orders of magnitude. It is suitable for satisfying the requirements of methods such as EPA 245.7.

The Hydra AF Gold is a fully automated atomic fluorescence analyser equipped with gold amalgamation capability for pre-concentration of Hg from ultralow-level samples. This yields limits of detection well below 1 ppt (typically <0.05 ppt) and is intended to address the needs of the analyst who routinely works in the sub ppt range.

The Hydra C is suitable for determining mercury in a variety of matrices including solids without the need for acid digestion, chemical oxidation or reduction, with DL <0.01 ng. The analyser uses thermal decomposition to release bound mercury from the sample matrix and is designed to meet all the analytical requirements of USEPA Method 7473.
