Gas Chromatography-Mass Spectrometry (GC-MS)

To improve the accuracy of chemical molecule structure analysis, Gas Chromatography-Mass Spectrometry (GC-MS) combines the functions of Gas Chromatography (GC) and Mass Spectrometry (MS). Drug detection, fire investigation, environmental analysis, investigating explosives, and identifying unidentified materials are some applications of GC-MS. Utilizing its extensive network of laboratories, Infinita Lab, USA, provides this test to its clients in the USA and other locations.

Overview

The analysis of the sample with the use of Gas Chromatography-Mass Spectrometry (GC-MS) analysis, which is an advanced analysis technique, involves the use of the identification and quantification capabilities of Mass Spectrometry and the separation capabilities of Gas Chromatography to detect, identify, and quantify volatile and semi-volatile organic compounds in complex sample matrices. The GC-MS analysis of the sample will provide chemists, researchers, and failure analysts with accurate, sensitive compound identification and quantitative concentration information.

Scope, Applications, and Benefits

Scope

GC-MS works on the principle of separating a mixture of samples using a gas chromatography column, then introducing the separated constituents into a mass spectrometer to analyze their fragmentation patterns and identify both unknowns and knowns simultaneously in a single run.

GC-MS analysis evaluates:

Identification and quantification of volatile and semi-volatile organic compounds in complex matrices
Trace-level contamination detection and unknown compound identification in materials and products
Residual solvent, monomer, and additive analysis in polymer and chemical formulations
Flavor, fragrance, and aroma compound profiling in food, beverage, and consumer products
Outgassing and emissions analysis of materials and assembled components

Applications

Polymer, adhesive, and coating materials requiring residual solvent and outgassing analysis
Food, beverage, and flavor industry compound profiling and contaminant screening
Pharmaceutical and chemical manufacturing impurity and unknown compound analysis
Environmental sample analysis for volatile organic compound detection and quantification
Forensic and failure analysis investigations requiring unknown compound identification

Benefits

Provides highly sensitive compound identification and quantification across complex sample matrices
Identifies unknown contaminants and trace-level compounds in materials and finished products
Supports material characterization and contamination investigation programs
Delivers traceable, laboratory-certified analytical data for engineering
Reduces product risk by detecting chemical contamination and formulation anomalies early
