Gas chromatography–mass spectrometry (GC-MS) is a hybrid analytical technique that couples the separation capabilities of GC with the detection properties of MS to provide a higher efficiency of sample analyses. While GC can separate volatile components in a sample, MS helps fragment the components and identify them based on their mass.

GC-MS provides enhanced sample identification, higher sensitivity, an increased range of analysable samples, and faster results, which enable a whole new range of applications for GC-MS in several areas.

The Agilent 5977A MSD/7890B GC system delivers a higher level of performance and productivity with:

• The industry's highest S/N and lowest IDL
• The new powerful MassHunter Quantitative and Qualitative Analysis software
• Eco-friendly features that save energy and time
• Integrated Intelligence to support methods development and system optimization
• Enhanced communication between the GC and MSD for more efficient and safer operation

Gas chromatography (GC) is used to separate and detect small molecular weight compounds in the gas phase. A GC is popular for environmental monitoring and industrial applications because it is very reliable and can be run nearly continuously.

A GC is typically used in applications where small, volatile molecules are detected and with non-aqueous solutions. Flame-ionization detection (FID) is a good general detector for organic compounds in GC that detects the amount of carbon in a sample. FID is unaffected by non-combustible gases and water.

The 7890B Gas Chromatograph (GC) System is the world’s most widely used GC system. It features accurate temperature controls and precise injection systems, plus enhanced Electronic Pneumatic Control (EPC) modules for the best retention times.

Compound specific isotope analysis provides a deep level insight into many geochemical and forensic applications and is considered a crucial technique for many laboratories. The GC5 offers exceptional sensitivity for low concentration analytes whilst maintaining chromatographic integrity of sample peaks during compound conversion.

The GC5 system is connected to the Agilent 7890B GC system to create the highest performance GC-IRMS system for research.

We offer measurement of δ¹³C and δ²H in compounds separated by capillary chromatography. The GC5 Furnace system offers high temperature for δ²H pyrolysis of compounds at 1450 °C.
