Description: The mercury analyzer is used to determine mercury concentrations in liquid and solid samples. The DMA-80 is based on the principles of sample thermal decomposition, mercury amalgamation and atomic absorption detection.
Analytical Method: Mercury in liquids and solids is analyzed by thermal decomposition, amalgamation and atomic absorption spectrometry using EPA Method 7473. Samples must be stored at 4ºC.
Sample submission: Water samples may be submitted to the water quality laboratory chemist for analysis.
Training: Student researchers and faculty who may be interested in training on how to operate the instrument and interpret the data, please contact the water quality laboratory to schedule training and time on the instrument. While the number of training hours may vary, depending on the student's knowledge and analytical skills, we require a minimum of four training hours prior to allowing the student to independently operate the instrument.
