Markes International

We are a specialist manufacturer of instrumentation for detection of trace-level volatile and semi-volatile organic compounds (VOCs and SVOCs). We have a well-deserved reputation for application expertise in the field of thermal desorption, supplying a comprehensive range of instruments, sampling equipment and consumables that enhance the analytical capability of GC–MS. In 2018 we launched Centri, an automated multi-mode sampling platform for pre concentration of analytes from liquid, solid and gaseous samples. Centri has meant we have extended our reach for sample preparation techniques into Headspace, HS-trap, SPME, SPME-trap and high-capacity sorptive extraction (with trap) in addition to thermal desorption.
