About Markes International
Markes International is a supplier of specialised analytical technologies that enhance the sensitivity, separation performance and interpretability of gas chromatography (GC) and GC–mass spectrometry (GC–MS). The portfolio comprises thermal desorption instruments, automated sample extraction and concentration platforms (Centri, Headspace, SPME, High-capacity sorptive extraction), sample tubes and sampling supplies, the MTS-32 Pro air sampler, and, from SepSolve, GC×GC modulators (INSIGHT), time-of-flight mass spectrometers (BenchTOF2) and the ChromSpace and ChromCompare+ software for data analysis and chemometrics. The systems operate cryogen-free, solvent-free and bottle-free and enable trace analysis of volatile and semi-volatile organic compounds ((S)VOC) in gases, liquids and solids. Fields of application include environmental monitoring, materials testing, food and beverage analysis, aroma and fragrance analysis, petrochemistry, defence and forensics, as well as clinical research. The company was founded in 1997 in Bridgend (Wales) and distributes its products worldwide, with local assembly in China.
