Trace Level Determination of Perfluorinated Compounds in Water using Ion Chromatography

The human and environmental exposure potential of perfluorinated alkyl sub-stance such as perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) has become the subject of intense research. Metrohm (Switzerland) presents an easy-to-use and economic direct-injection method for PFOA and PFOS determination in drinking water. The currently used method for the determination of anionic perfluorinated surfactant is LC-MS/MS. The analytical methods for the determination of PFOS and PFOA in water samples generally employ a C18-SPE column, either with or without ion pairing or acidification, followed by LC-MS/MS. However, this method suffers from relatively high runn-ing and investment cost.
The new Metrohm method is a good alternative regarding both investment on instrumentation and usability. The method is based on surpressed ion chromatography with isocratic elution on a reserved-phase column thermostated at 35'C using an aqueous mobile phase containing boric acid and acetonitrile. The used detection technique is conductivity. While PFOA and PFOS determination in low salt-containing water samples can be performed using straightforward direct injection chromatography, samples with higher alkaline-earth-metal concentration, e.g. tap, lake, sludge or river water samples, should pass over a cation exchanger such as Metrohm's Sample Prepation Module <> prior to separation.

Dissolved Oxygen Optical Sensor Designed for Process Applications

The new Rugged Dissolved Oxygen (RDO) PRO sensor from In-Situ (USA) is designed for demanding process applications and features an abrasion-resistant foil that withstands fouling, high sediment loads, and rapid flow rates. The sensor cap is preloaded with calibration coefficients to speed set up and eliminate programming errors. The RDO PRO sensor offers open-architecture communication protocols, including Modbus over RS485, SDI-12 (version 1.3), or 4-20 mA signal outputs. The RDO PRO eliminates the need for costly external transmitters or controllers and operates on a 8 to 36 VDC input or 4-20 mA three wire current loop. Corrosion-resistant construction and durable sensing foil design provide consistent, reproducible results (<0.05 mg/L reproducibility) in demanding environments. The RDO PRO offers reliable, low-maintenance to water quality specialists in municipal or industrial water and wastewater treatment plants, aquaculture settings, dam discharge applications, and food/beverage process control environments.
The In-Situ RDO sensor measure Dissolved Oxygen using the principle of "dynamic luminescene quenching" according to ASTM Method D888-05, Test Method C. Compared to Clark-cell type sensors, the RDO PRO sensor can lower the total cost of acquiring consistent, high-quality data. Th In-Situ RDO sensor significantly reduces instrument checks and recalibration. The RDO PRO sensor is factory-calibrated and requires a quick two-point calibration upon deployment. The calibration can last for several months if sensor fouling is minimal and if the foil is not mechanically damaged or removed. If fouling is high, the sensor can typically be cleaned and redeployed without recalibration. Field-replaceable caps streamline maintenance, reduces costs, and eliminate programming errors.

Pumps Help Oceanographic Research to Measure Carbon Dioxide is Seawater

The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has developed a miniaturized observation device to measure carbon dioxide (CO2) in seawater, relying on Tecan's (Switzerland) Cavro XCalibur Pump for accurate automated pipetting. JAMSTEC is involved in a wide range of basic marine-related research, including collection and dissemination of information that helps to understand changes in the earth's environment. It is one of the activities of the japan EOS Promotion Program, funded by MEXT, Japan. "It is necessary to monitor CO2 concentrations in order to predict future climate change," explained Dr. Yoshiyuki Nakano, Research Scientist at JAMSTEC's Mutsu Institute for Oceanography in Aomori, Japan. " We developed a device that calculates the CO2 concentration in seawater by analyzing a pH indicator solution, using two Cavro XCalibur pumps to aspirate and mix pure water and concentrated pH indicator for each measurement. The volumes of indicator and water used are critical for reliable results, and the accuracy of the Cavro XCalibur Pump allows us to achieve exactly the concentration we aim for, while the pump's broad selectable volume range allows us to choose the exact concentration we want".
"We also chose the Cavro XCalibur Pump because an important design goal was to make the CO2 sensor small and light; the pump also offered high accuracy and was capable of maintenance-free operation for long periods, " added Dr. Nakano.

Reliable Measurements Also in Polluted Water

Requirements on the quality of water above all depend on the application. Depending on the purpose of use and application of water, the raw water is to be treated correspondingly. Chlorine dioxide has long been known as disinfectant in drinking water treatment and is now also increasingly used for oxidation and disinfection of polluted waters such as industrial, process, and cooling water. The chlorine concentrations prescribed by EU directives can be met by using the corresponding measuring and control technology. In order to avoid random sampling, monitoring can be implemented reliably and comfortably with amperometric sensors by ProMinent (Germany). ProMinent have launched their new dirt-tolerant chlorine dioxide sensor CDR 1 mA.
The design of the sensor type CDR 1-mA was modified such that it can be used especially in polluted industrial, process and waste water as well as in cooling water applications or surfactant-polluted waters. This is ensured by a dirt-tolerant, non-porous diaphragm protect the sensitive measuring electrodes against the sample medium. The diaphragm protect because it is permeable for chlorine dioxide but not for interfering dissolved and undissolved water components. The sensors provides a temperature-compensated 4...20 mA signal for measurements in a temperature range of 1 to 55'C. Precise measurements can be realised in a pH range of 1 to 10.0.
