Powerful products for tough applications

Our thermal desorption (TD) instruments have for over 20 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.
