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.

Dexter, MI (April 24, 2024) - QED Environmental Systems, Inc., a leading manufacturer of innovative environmental products and subsidiary of Graco Inc. (NYSE: GGG), announces the new single-use Combo Core™ soil sampler for field preservation VOC analysis.

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 PFAS-free designation, making it ideal for the collection of soil core samples for PFAS analysis under EPA Method 537M. The system is also suitable for the collection of VOCs and 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- and 10-gram 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 centre plunger.

David Kaminski, Senior Vice President at QED Environmental Systems, said: "Customer feedback has been critical to the development of our new Combo Core™ tool. We have been sure to retain all of the benefits that made the renowned Terra Core® system so popular with technicians, alongside addressing some of the challenges experienced with single-use samplers.

"Namely, the standout here was a lack of flexibility. Now, with the ability to collect 5- and 10-gram samples of a range of VOCs, SVOCs, and PFAS all from a single device, technicians should be well-equipped to handle any challenge that they may be presented with out in the field."

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

David concluded: "The new Combo Core™ system is a veritable Swiss army knife for any technician working in the field, putting an end to the need to keep multiple sampler sizes on hand and in stock. We look forwards to bringing it to market and can't wait to see how it is received."
