Example Data
Denitrifi cation StudiesThe HPR-40 DSA was used to investigate denitrification by Pseudomonas stutzeri in a static lakewater column. Continuous real-time measurement of gases enabled the dynamics of the process to be investigated. Concentrations of 17 mmol/L nitrate and 10 mmol/L nitrite were identified as optimal for denitrification under nutrient-limited conditions (i.e., produced the highest concentrations of N2). Available carbon was the major rate-limiting factor in lakewater when nitrate or nitrite was present. No stratification of the process with depth was observed, and aerobic denitrification was apparent under all the conditions employed.
PPT Level Detection of Volatiles in Water The HPR-40 DSA was used to detect trace amounts of CH3SCH3 (Dimethylsulfide DMS) in ocean water. DMS is a naturally occurringsubstance produced from micro-organisms and related to globalclimate change and regulation.
The amounts which were detected in this application go down to 60 ppt(parts per trillion), which corresponds to dilute concentrations of DMSof less than 1 nML-1.
The diagrams show the calibration curve and raw data obtained fromDMS solutions in different concentrations.
