Micro-Electron Capture Detector (Μecd) - Agilent Technologies 7890A GC Safety Manual

Micro-Electron Capture Detector (µECD)
The µECD contains a cell plated with 63Ni, a radioactive isotope. The beta
particles released at the energy level in the detector have little penetrating
power—the surface layer of the skin or a few sheets of paper will stop most of
them—but they may be hazardous if the isotope is ingested or inhaled. For this
reason, handle the cell with care. Cap the detector inlet and outlet fittings
when the detector is not in use. Never introduce corrosive chemicals into the
detector. Vent detector exhaust outside the laboratory environment.
Refer to the safety documentation provided with the detector for important
details about safety, maintenance, and compliance with local government
regulation.
Materials that may react with the
WA RN ING
products or to cause physical degradation of the plated film, must be
avoided. These materials include oxidizing compounds, acids, wet
halogens, wet nitric acid, ammonium hydroxide, hydrogen sulfide, PCPs,
and carbon monoxide. This list is not exhaustive but indicates the kinds of
compounds that may cause damage to
