Typical column types

Capillary columns are commonly used for this class of equipment, offering high separation efficiency.

Detector types

This unit includes a Mass Spectrometer (MS) detector. Flame Ionisation Detectors (FID) and Thermal Conductivity Detectors (TCD) are also commonly found on units of this type.

Temperature range

Oven temperatures typically range from ambient to 450°C, allowing for analysis of various compounds.

Power supply

Units of this type commonly require a standard laboratory power supply, typically 230V, 50Hz, single-phase.

Carrier gas

High-purity helium, nitrogen, or hydrogen are typically used as carrier gases.

Automation

This system includes an autosampler, which is typical for automated sample injection and increased throughput.

• What is the primary function of a GC/MS system?

  A Gas Chromatography-Mass Spectrometry (GC/MS) system separates volatile and semi-volatile compounds in a sample using gas chromatography and then identifies them based on their mass-to-charge ratio using mass spectrometry.

• What kind of samples can be analysed by this equipment?

• What are the typical maintenance requirements for a GC/MS?

• Does this unit come with software and a PC?

• Can this system be upgraded or reconfigured?

Chromatography systems command strong respect within analytical and pharmaceutical sectors. Buyers typically prioritise equipment with verified maintenance records and clear calibration history, as these directly affect analytical accuracy. Used units from established manufacturers remain highly valued for their reliability. Key strengths include reproducible results, robust construction, and established spare parts availability. Industry sentiment reflects confidence in these systems when sourced from reputable suppliers with transparent service documentation.
