Combo Core Soil Sampler PFAS Soil Sampler for VOC Analysis

June 6, 2024
QED Environmental Systems' Combo Core sampler combines the capacities of 5 and 10-g sampler sizes into a single tool field preservation VOC analysis.

Single-use Combo Core soil sampler for field preservation VOC analysis collects 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 sampler has an easy-to-use T-shaped handle and collects both 5 and 10-g samples from a single tool, eliminating the need to carry multiple sampler sizes. To switch between the two, sampling technicians lift and twist the center plunger.

With the ability to collect 5 and 10-g 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 out in the field.

The soil sampler helps make transfer quicker and easier, with the barrel easily fitting into standard 20 and 40-ml vials to help reduce spilling

To reduce the environmental impact of the single-use system, all Combo Core systems are manufactured with Bio-Tec EcoPure biodegradable additive.
