The Combo Core system is set to succeed the popular Terra Core soil sampling tool, specifically designed for collecting core samples for VOC analysis using field preservation. Molded from virgin-grade polypropylene, the Combo Core is the first tool from QED that carries the per- and polyfluoroalkyl substances (PFAS)-free designation, making it ideal for the collection of soil core samples for PFAS analysis under U.S. Environmental Protection Agency (EPA) Method 537M. The system is also suitable for the collection of VOCs and semi-volatile organic compounds (SVOCs) under EPA Method 8260 and EPA Method 8270 respectively.

The new sampler retains the hardy design and easy-to-use T-shaped handle of the original, while also offering a number of additional benefits to the end user. In an industry-first development, the Combo Core soil sampler can collect both 5 g and 10 g samples from a single tool, eliminating the need to carry multiple sampler sizes. To switch between the two, sampling technicians need only lift and twist the center plunger.

The Combo Core soil sampler has been purposely designed to help make transfer quicker and easier, with the barrel easily fitting into standard 20 ml and 40 ml vials in to help reduce spillage.

In order to reduce the environmental impact of the single-use system, all Combo Core systems are manufactured with Bio-Tec EcoPure, a unique biodegradable additive.
