Germanium tetrahydride
Analysis:
Germanium, tétrahydrure de
Recommended method by the IRSST:
Method: OSHA - IMIS1360
Sampling protocol
Sampling device:
Activated charcoal tube 100/50 mg
Parameters:
Flow rate: 0,2 L/min
TWA sampling volume: 48 L
STEL sampling volume: -
Remarks:
A mixed cellulose ester filter can be considered preceding the activated charcoal tube to eliminate the germanium compounds present as aerosol. Contact the IRSST before sampling.
Analytical protocol
Principle:
Electrothermal atomic absorption spectrophotometry (ET-AAS)
