Print- Method description
Solid or liquid samples are dried and thermally decomposed in a continuous flow of oxygen and the combustion products are passed over a hot catalyst bed. The remaining decomposition products are carried to a gold amalgamator that selectively traps mercury. After the removal of any remaining gases or decomposition products, the amalgamator is rapidly heated to release the mercury in the vapor form. The vaporous mercury is analyzed using atomic absorption spectrophotometry at 245 nm with quantitation as compared to a calibration curve.

Common Mercury Test Testing Questions
We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
