Developed by Beijing Beifen Raleigh Analytical Instrument (Group) Co., LtdMAS-100Type alkylmercury analyzer, meeting the requirementsHJ977-2018The Water QualityDetection of alkylmercurypurge-and-trap/gas chromatography-Cold Atomic Fluorescence Spectroscopy "is a national environmental protection standard applicable to batch analysis of samples.

Methylmercury and ethylmercury react with the derivatizing reagent tetrapropylborate sodium in aqueous solution, generating methyl propyl mercury and ethylpropyl mercury with certain volatility. They are then purged with argon gasTenaxAfter capturing, use gas chromatography-Measurement using a cold atomic fluorescence detector.

Specialization of General Instruments

During installationAFDAt the same time, other detectors can also be installed（FID、ECD、TCD、FPD）Satisfy users' analysis of other applications.

Active exhaust gas capture system

The mercury vapor passing through the detector will eventually be captured by a gold wire adsorption tube to ensure effective capture of mercury vapor.

Efficient separation using capillary chromatography columns

Higher column efficiency and faster separation speed result in higher sensitivity for methylmercury and ethylmercury.
