Markes - Model C-EZVOCPO -Easy-VOC Grab-Sampler Pump Kit
Easy-VOC is a hand-operated pump kit for rapid ‘grab-sampling’ of precise volumes of air/gas directly onto sorbent tubes, for subsequent analysis by thermal desorption (TD). In contrast to canister sampling, grab-sampling onto sorbent tubes allows analytes from a wider volatility range to be sampled (in the region of C2/3 to n-C44), plus many polar and reactive species.
Includes CapLok tool and carry case.
- Enables sampling of precise volumes of air (50 mL and 100 mL intervals)
- Portable and can be used remotely without batteries or electrical power
- Provides snapshot into target compound concentration at a given time
- Minimises risk of analyte breakthrough and water retention by allowing small sample volumes
- No need for calibration means no additional tools are required
The Easy-VOC kit contains:
- Easy-VOC grab-sampling pump
- CapLok™ tool
- Carry-case
Easy-VOC allows samples to be collected onto single-bed or multi-bed sorbent tubes (¼″ or 6 mm o.d.), extending the application range and allowing quantitative retention of SVOCs, VOCs and VVOCs in a single sampling period.
Performance in many applications is very similar to constant-flow pumps – reproducibility is1 ppb when using quadrupole MS.
Easy-VOC is ideal for entry-level users undertaking active sampling – it doesn’t require calibration and is simple to use and robust. It provides a snapshot into target compound concentrations at a given time as opposed to a time-weighted average, and provides excellent repeatability and comparison of data. The pump itself is lightweight, easy to store and ship using the carry-case provided, and is user-maintainable.
