High-sensitivity trace-level measurement of water in organic solvent was performed on-line, continuously in real-time. Parts-per-million sensitivity (10-ppm detection limit) was achieved which previously could only be achieved by the Karl-Fischer titration method.

Organic Micro-pollutants are low and trace levels of synthetic organic substances released in water through human activity. They can be found in industrial, agricultural and domestic wastewater streams. Some of the most difficult-to-treat wastewater contains micro-pollutants such as persistent organic pollutants (POPs), herbicides and pesticides, personal care products (PCPs), toxic chemicals, carcinogenic and endocrine disruptive compounds (EDCs), and emerging contaminants.

Pulse-Flow respirometers can be used to assess biomass activity for aerobic and anaerobic reactions. In aerobic tests, cultures are combined with nutrients, trace minerals, and an organic substrate – such as acetic acid or ethanol. The maximum oxygen uptake rate reflects the amount of active biomass in the test culture.

Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.
