Ms Detector; Front Panel Status Indicator - Thermo Scientific Surveyor MSQ Plus Hardware Manual

MS Detector

Front Panel Status Indicator

Thermo Scientific
The MS detector provides sample ionization and mass analysis of samples injected with an
autosampler or samples infused with the reference inlet system. The Surveyor MSQ Plus MS
detector uses a quadrupole mass analyzer with an API source external to the mass analyzer.
The following components of the Surveyor MSQ Plus MS detector are described in this
section:
• Front Panel Status Indicator
• Rear Panel Controls and Connections
• Connection Between LC and MS Detector
• API Sources
• RF/dc Prefilter
• Mass Analyzer
• Ion Detection System
• Vacuum System
• Inlet Gas Hardware
One light-emitting diode (LED) is located at the upper right corner of the front panel of the
Surveyor MSQ Plus MS detector as shown in
Status LED.
Initially, when a Thermo Fisher Scientific service engineer installs the Surveyor MSQ Plus MS
detector turns on the forepump, the status LED is red. As the system pumps down, the LED
flashes yellow. After the vacuum reaches 10
operating speed, the LED turns solid yellow.
If you vent the system for a brief period of less than 2 hour (for example to perform
maintenance on the source block), wait 15 minutes after pumping down the system to place
the MS detector in the Operate mode. If the system has been in a vented state for more than a
brief period, pump the system down, and then wait a minimum of 8 hours before operating
the system.
