GC-MS analysis, semiquantitative
GC-MS (gas chromatography coupled with mass spectrometry) analysis is a method for the comparative, semi-quantitative evaluation of liquid samples with regard to identity, purity and presence of impurities. The substances detectable by this method are, as with any method limited, here by their molar mass and polarity. The method can be used, for example, to analyze solvent samples and solvent-based surface extracts for impurities. A typical field of application is the investigation of adhesion problems from the printing, laminating and labeling sector.
Substances with molecular weights of appr. 100- 700 Dalton (resp. app. 100- 700 g/mol) are principally detectable.
In short — AI-generated
The GC-MS analysis identifies and quantifies chemical substances within liquid samples or surface extracts by separating them through gas chromatography and identifying them via mass spectrometry. This method is specifically designed to detect organic compounds with a molecular weight between approximately 100 and 700 g/mol.
The resulting data provides a semi-quantitative overview of impurities, helping to identify potential contaminants in solvents or packaging materials. In practice, this analysis is primarily used to investigate the root causes of adhesion failures in printing, laminating, and labeling processes.
