Gas and Electrical Connections

Gas and high-voltage electrical connections enter through the front plate of the interface and

connect internally through the ion source housing. When the ion source is installed on the mass

spectrometer, all of the electrical and gas connections are made.

Ion Source Latch

A latch disables the high-voltage power supply for the mass spectrometer and the source

exhaust system if:

• The ion source housing is not installed or is improperly installed.

• A probe is not installed.

• The mass spectrometer senses a gas fault.

Source Exhaust System

A passive pressure exhaust system removes ion source gases through a drain port without

introducing chemical noise. The drain port connects through a drain chamber and a source

exhaust pump to a drain bottle, and from there to a customer-supplied exhaust ventilation

system. For more information on the requirements for the source exhaust system, refer to the

Site Planning Guide for the mass spectrometer.

Item Description

1 Electrode adjustment nut (black collar) that adjusts the extension of electrode tip

2 Bronze retaining ring that fastens the probe to the probe tower on the ion source

housing

3 Electrode tip through which samples are sprayed into the sample inlet area of the ion

source

WARNING! Toxic Chemical Hazard: Be sure to use the source exhaust system to

safely remove sample vapor exhaust from the laboratory environment. For

requirements for the source exhaust system, refer to the AB SCIEX TripleTOF
