Maintaining the Calibration Gas Module

Thermo Scientific
The calibration gas module on the TSQ 9000 mass spectrometer is very easy to maintain. It is
inside the front door of the instrument, and you only refill the calibration gas reservoir every
one to two years.
The calibration compound is a liquid whose vapor is introduced into the ion source by the
calibration gas module and the associated tubing. When the calibration compound is ionized,
it produces a rich spectrum of ions that are well distributed across the mass range of the
instrument and which are used for tuning and calibrating the mass spectrometer. The TSQ
9000 mass spectrometer uses FC 43, which contains perfluorotributylamine (PFTBA) as its
calibration compound.
Note See the ISQ and TSQ GC-MS Spare Parts Guide for information about ordering
calibration gas components.
