About Markes

Smarter decisions begin with deeper insight

Markes, a Velaris brand, is a world-leading developer of technologies that enhance the analytical power of GC for both routine & research work. Its award-winning thermal desorption & automated sample extraction/concentration systems enable highly sensitive trace-level analysis of volatile & semi-volatile organic compounds across gases, liquids & solids. These capabilities are complemented by its subsidiary, SepSolve, which supplies advanced GC and GC×GC platforms, TOF MS & specialist software for data mining, chemometrics & chromatogram comparison.

Together, Markes and SepSolve deliver integrated workflows from sampling to confident data interpretation, supporting laboratories working in environmental monitoring, materials testing, food/beverage analysis, flavour and fragrance chemistry & clinical research.

Powerful products for tough applications

Our thermal desorption (TD) instruments have for over 25 years been the mainstay of our business. Thermal desorbers such as our flagship UNITY-xr™ and TD100-xr™ systems use the power of trap-based focusing to concentrate samples into the small volumes needed to ensure highly sensitive GC–MS analysis.

Our sample preparation equipment is represented by our Centri^® platform, which combines several techniques for the extraction and enrichment of samples. As a result, Centri enables analysts to analyse different sample types and maximise throughput, all on a single system.

Supporting these products is a broad range of stand-alone sampling accessories and supplies to ensure reliable ongoing performance, and the largest available portfolio of sample capture equipment for TD.

Our instruments adhere to regulated standard methods used worldwide, and their application scope is broad – from environmental monitoring to homeland security, and from consumer products to foods and beverages. In addition to these well-established fields, our systems are also widely used in advanced research, such as breath sampling for disease diagnosis, and investigations into chemical ecology.

Multi-award-winning innovations

Our teams have pioneered numerous innovations in thermal desorption and associated sampling equipment.

Some of our most important breakthroughs include inert valving for wide analyte compatibility, backflush trap desorption for a broad single-run analyte range, cryogen-free cooling systems, and re-collection of split flows for streamlined repeat analysis.

Global reach, talented staff

Our systems are sold worldwide, both through our own offices and our network of distributors, and our customers encompass research, government and industrial/service laboratories.

Our factory, technical centre and headquarters are at Bridgend near Cardiff (UK), and offer over 50,000 sq.ft of space for research, manufacturing, engineering, marketing and customer demonstration facilities. Our overseas support centres and laboratories are located in Offenbach am Main (Germany), Sacramento (California, USA) and Shanghai (China). We are also represented in Toronto (Canada), in the technical facility of SepSolve. Across these locations we employ thermal desorption and sample preparation experts, alongside the sales and customer support teams, to help ensure our customers have access to our advice whenever they need it.

Powerful partnerships

SepSolve offer products as part of broader application-focused packages, including advanced GC equipment (such as GC×GC), mass spectrometers and data-analysis software. In this way, SepSolve is able to meet the challenges of the entire workflow, as well as offering product packages tailored to the needs of individual laboratories.

Markes and SepSolve are part of Velaris, who harness applications and engineering expertise to improve all aspects of the gas chromatography workflow and deliver better business and scientific outcomes for both research and routine laboratories.

The Verlaris portfolio combines robots and integrated devices which scale with the needs of our end users, allowing them reliable, precise analysis in their important daily work. Sold under a collection of well-established brands including Skalar Analytical, LCTech, PromoChrom, TE Instruments, EST and GERSTEL, it combines over 50 years of experience in the field.​
