Markes International has launched a next-generation passive sampler that combines all the benefits of radial and axial VOC samplers, and which the company says will ultimately make large scale air monitoring studies easier to run and more affordable. The Pocket Diffuser Sampler (POD Sampler) provides better sensitivity, higher accuracy and faster response times, whilst also improving on ease of use and re-usability compared to other passive samplers. The POD cartridges can be reconditioned and reused over 100 times and the sampler itself can be used indefinitely. The POD Sampler was developed in partnership with the European Commission’s Joint Research Centre (JRC) in Ispra, Italy, the European reference laboratory for air pollution. The POD Sampler is compatible with any commercial thermal desorption system.
