HKL-WA-5A conforms to ASTM D5954 Standard Test Method for Mercury Sampling and Measurement in Natural Gas by Atomic Absorption Spectroscopy and ASTM D6350 Standard Test Method for Mercury Sampling and Analysis in Natural Gas by Atomic Fluorescence Spectroscopy. It is specially designed for measurement of mercury in air and gaseous matrices (eg. Hydrocarbon gaseslike Natural Gas, Shale Gas, LPG/LNG and more) in compliance with widely estabilished and accepted technique of Gold-Amalgamation and detection by Atomic Spectroscopy - with the choice of either Atomic Absorption (AA) or Atomic Fluorescence (AF). This tester presents many unique levels of automation and functions to help laboratory accomplishes productivity, unmatched versatility, efficiency and operational labor saving. HKL-WA-5A is compact in design to allow for easy transport for field operation and measurements.
