ROCK voc® System
Combines precision, practicality, and efficiency for advancing remediation practices
The ROCKVOC® System eliminates VOC loss during sampling and processing, ensuring accurate, reliable results—a significant improvement over traditional methods that compromise data quality through unquantified VOC loss.
Key benefits:
- Improves detection of hidden contamination sources, e.g., building materials assessment during vapor intrusion studies.
- Makes rock matrix analysis accessible for remediation practitioners.
- Features stainless steel VOA vials, hydraulic press compatibility, and temperature-controlled VOC screening.
System Specifications:
Princeton Geoscience’s patented ROCK System advances VOC sampling by crushing rock and concrete sub-samples directly into solvent-filled VOA vials, which eliminates exposure to air and unquantified VOC loss.
It includes a standard benchtop press fitted to a unique crushing pestle and base unit that ensures the entire sample is thoroughly crushed with just a few turns of the vial. The stainless steel VOA vials are designed to withstand this pressure, as well as be compatible with standard laboratory equipment. The capping unit accommodates the connection of influent/effluent tubing, enabling introduction and removal of gases.
A thermal insertion probe connected to the base unit provides temperature-controlled screening, which allows for simulation of specific conditions, such as the boiling points of targeted VOCs, thereby eliminating variables common to typical field
screening approaches.
