使用直接测汞仪测定口红唇膏中的汞含量

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. 莱伯泰科DMA-80测汞仪(汞分析仪)
