Article Abstract:
Advanced Instruments has started offering the GPR-16HP oxygen analyzer that incorporates the innovative Pico-Ion sensor technology. The sensor, which is touted to be able to detect oxygen changes below 1 ppb, has a 90% FS response time of less than 20 s and recovers from exposure to high concentrations of oxygen in under 10 minutes. In addition, the sensor, which has an expected life span of 18-24 months, has a bypass loop that permits it to be isolated for mobile cart applications.

Article Abstract:
The identification and quantification of thermal hazards in the design of safety systems can be done through the use of concepts and data provided by chenical thermodynamics, kinetics and calorimetry. The process hazard analysis involves four steps: deskstop screeing of the reaction components for potential thermal hazards, determination of the thermal stability of the components, isothermal characterization of the process and adiabatic characterization of the reaction mixture.

Article Abstract:
Applied Analytics Inc has introduced a solid-state tail-gas analyzer for in situ examination of sulfur-containing compounds in Claus plants. It is able to measure from 190 to 1,100 nm spectra, with a 1-nm resolution. It has an absorption range of two absorbency units (AU) compared to the 1 AU range of most analyzers. It is also half the size of comparable units and costs 40% less.
