Manufacture of carbon tube pumps.
Founded in 2007, Ripo specializes in innovative products such as carbon-tube sampling pumps.
Soil Gas Sampling
Built and calibrated in Denmark
Every pump is assembled, tested and calibrated in our Rødovre workshop and shipped with a traceable certificate. Closed-loop flow control, automatic volume dosing and an on-board run log — the parts of a soil gas sample that have to be exact.
Questions
and answers
That is set by your target compounds and the laboratory’s method, not by the pump. Activated carbon and charcoal cover most petroleum and solvent work; Tenax TA and multi-bed tubes suit wider VOC screens. Any 6 mm OD tube fits the inline holder.
Follow the analytical method and the sorbent’s safe sampling volume. A common starting point is 100–250 mL/min for 1–4 litres total. The pump auto-stops at the volume you set, so it can run unattended.
Each unit ships with a traceable flow calibration certificate. We recommend annual re-calibration, or sooner if the field log shows the delivered flow drifting from setpoint.
Yes. The same low-flow, volume-controlled sorbent-tube method applies to sub-slab ports, crawl spaces and indoor air. Only the probe and fittings change.
About 14 hours of continuous sampling at 250 mL/min on one charge. A full charge over USB-C takes roughly three hours, and a hot-swappable battery pack is available for long days.
