Precise and rapid determination of total mercury in Lipstick can be performed using Direct Mercury Analyzer. Such an instrument requires no sample wet chemistry or pretreatment. Once a weighed sample portion is introduced into the instrument, analysis is complete in six minutes. Direct analysis of mercury, using the integrated sequence of Thermal Decomposition, Catalyst Conversion, Amalgamation, and Atomic Absorption Spectrophotometer, is described in EPA 7473 and is validated for laboratory as well as field analysis. 萊伯泰科DMA-80測汞儀(汞分析儀)
