Additional CRC gases (methane, ethane, propane, fluoromethane,
tetrafluoromethane, nitrous oxide, carbon monoxide, carbon dioxide,
acetylene, nitrogen, neon, xenon, krypton, sulfur hexafluoride) are
also supported for the iCAP TQ/TQs ICP-MS. Prior to use, your local
Thermo Fisher Scientific representative must be contacted to support
you with all necessary information and to guarantee an optimal
installation and configuration of the instrument.
