Thermo Scientific
list the permitted gases used for CR in the iCAP TQ
ICP-MS and iCAP TQs ICP-MS instruments.
iCAP RQ ICP-MS 2-Channel Systems
a
:
Hydrogen or mixtures with helium
Used for the removal of polyatomic and isobaric interferences
by charge-transfer reactions and mass-shift reactions
(hydrogen adducts).
NOTICE
A hydrogen sensor must be installed in the vicinity of the
instrument.
Ammonia mixtures with helium
Used for the removal of polyatomic and isobaric interferences
by mass-shift reactions (ammonia cluster adducts).
NOTICE
Maximum content of ammonia: 1%. If an ammonia sensor is
installed in the lab, 35%.
a
If the torque plate of your system does not mention “suitable for Hydrogen use,” the specifications listed for 1-channel systems apply to your system.

Table 5-29.
iCAP TQ/TQs ICP-MS: Gases for CR use
Material
Used for
Helium
Used for the removal of polyatomic interferences by kinetic
energy discrimination.
Oxygen or mixtures with helium
Used for the removal of polyatomic and isobaric interferences
by mass-shift reactions (oxidation).
Hydrogen or mixtures with helium
Used for the removal of polyatomic and isobaric interferences
by charge-transfer reactions and mass-shift reactions (hydrogen
adducts).
NOTICE
A hydrogen sensor must be installed in the vicinity of the
instrument.
Ammonia or mixtures with helium
Used for the removal of polyatomic and isobaric interferences
by mass-shift reactions (ammonia cluster adducts).
NOTICE
An ammonia sensor must be installed in the vicinity of the
instrument.
NOTICE
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.
