Biospectrometry

Biospectrometry is the application of mass spectrometry in the field of the life sciences.

This field uses fast chromatographic techniques, enzymatic chemistries, and surface chemistries and combines them with mass spectrometry and advanced software to better enable biomolecular research and facilitate data interpretation.

This section describes:

• System components

• Mass spectrometer

• Vacuum System

• Front panel indicators

• Computer components

Parts of the Voyager-DE STR system include:

•     Mass spectrometer

A time-of-flight mass spectrometer, described in Section 1.6.2, Mass Spectrometer. The high-vacuum system of the mass spectrometer is described in Section 1.6.3, Vacuum System.

•     Computer/Data System

A computer that operates the Voyager control software and the Voyager processing software. You control the mass spectrometer using the computer.

•     Digitizer (not shown)

An analog-to-digital converter that allows the signal from the mass spectrometer to be transferred to the computer.

The standard digitizer provided is a 4 GHz digitizer.

•     Video monitor

A monitor that displays a real-time video image of the sample spot for examination during acquisition.

•     Control stick

A peripheral device that controls position of the sample plate in the mass spectrometer. Allows you to start and stop acquisition and transfer data to the processing software.

The parts of the Voyager-DE STR Biospectrometry mass spectrometer are shown in Figure 1-18.
