The mechanical design and material science of pH-sensor technology have evolved dramatically over the last century. Current-day uses include a wide range of applications from high-purity pharmaceutical processing to wastewater treatment. Some of these applications pose high challenges to pH measurement, including high-temperature and otherwise harsh measuring environments, stability (particularly in...

ASA Analytics Plugging is not an issue with this phosphorus analyzer The ChemScan mini oP analyzer (photo) for ortho-phosphorus analysis features flow paths designed to avoid plugging. The analyzer uses large orifice sizes, compared to capillary tubes and needle valves of most other analyzers. The unit operates for three months between reagent addition, and any of the analyzer’s components can be...

Optoacoustic gas detection determines gas content via the measurement of acoustic pressure waves that are propagated as a gas is irradiated under an appropriately tuned light. A gaseous-mixture sample passes through a membrane into a measurement cell, which contains an infrared light source and a microphone. Incident light modulated at a specific frequency is briefly absorbed as intermolecular energy by...

A Low Parts Count Makes this CO 2 Monitor Economical Boasting an in-house design and accurate CO 2 detection between 0 – 10,000 ppm, the ZG106A-M has a uniquely low parts count, making it an economically competitive option for determining indoor air quality, safety, and other monitoring criteria. The device comes standard with a data logger, a CO 2 level alarm, and an extreme level indicator. —...

Infrared (IR) analyzers are widely used for gas, liquid and surface analysis. Up to now, the most common and inexpensive IR sensor has been a combination of filters (non-dispersive IR) — which have a restricted wavelength band — with a pyroelectric detector; alternatives, such as Fourier transform (FTIR) spectrometers, require an elaborate optical configuration and tend to be expensive. Now, an...

High-resolution x-ray diffraction Based on the Medipix2 application-specific integrated circuit (ASIC), the PIXcel is designed for sensitive, high-resolution x-ray diffraction applications. Consisting of over 65,000 pixels, each 55 x 55 microns in size and with individual readout circuitry, it delivers an unmatched dynamic range of 25 million counts per second per pixel row — thus eliminating the...

The standard way to test for toxicity in individuals who have been exposed to heavy metals is to take a blood sample and analyze it in the laboratory by plasma mass spectrometry, an expensive and time-consuming procedure. Now, a portable instrument that can do the same job in the field in 2 – 5 min, for one-tenth the cost, has been developed at Pacific Northwest National Laboratory (PNNL, Richland...
