In the chemical process industries (CPI), multiphase flow regimes in reactors, bubble columns, pipework and elsewhere in plants determine process efficiencies and safety. As a result, a considerable number of intrusive and non-intrusive techniques have been developed to recognize phase fractions. However, such techniques are very expensive and complex (such as tomography) or provide only localized...

Bartec GmbH (Gotteszell, Germany; has commercialized Hygrophil DTP, an optical dew-point sensor that uses a patented technique for accurately measuring moisture content and relative humidity (RH) of compressed air and other gas supplies. Conventional sensors that are based on capacitance, changes in resistance or thermal conductivity are limited in both the accuracy and range of...

    Most assets depreciate, losing value over time as a result of wear and tear, age, or obsolescence. Corrosion, like depreciation, results in the often hidden cost of a non-cash expense — measurable in terms of reduced operating life — that reduces the value of assets. Many engineers in the chemical process industries (CPI) see corrosion on a “straight-line basis” in...

Researchers at the University of Warwick ( and Leicester University (both U.K.) have used artificial nasal mucus to significantly enhance the performance of odor-sensing devices (electronic noses), which are used for quality control in, for example, the food industry. By coating the sensors with a mix of polymers that mimics the action of the mucus in a natural nose, the electronic...

NASA Goddard Space Flight Center (Greenbelt, Md.; invites companies to license a new non-destructive test (NDT) method for evaluating the degree of cure, variations in chemical composition and defect states in resin-based composites and metal oxides — data that is currently...
June 1, 2007
Scientists at the Universitat Autònoma de Barcelona (UAB; Spain;, in cooperation with the Institute of Chemical and Environmental Research (CSIC), have developed an electrochemical biosensor that can detect atrazine — a widely-used herbicide...

    Portable and fixed detectors for toxic and flammable gases are offering more choice and better value for the money, say experts, thanks to technology developments and strong market competition. In Europe, competition triggered by consolidation in the last five years has propelled the market out of the doldrums of the last couple of decades, according to a recent report from market consultancy...

    The beauty of fiber-optical spectroscopy is that small, inexpensive devices with no moving parts bring their capacity to where the samples are, rather than the other way round. As a result, spectra can be recorded in almost real time, which means that information about composition, concentration and other chemical parameters can be gathered alongside of temperature, pressure and flowrate. The...

A prototype of what is called the world’s fastest, wide-ranging hydrogen gas sensor has been constructed by a team of researchers, led by Professor Kazushi Yamanaka at the Dept. of Materials Processing, Tohoku University (Sendai, Japan;, together with Toppan Printing Co. and Yamatake Corp. (both Tokyo) and support from Ball Semiconductor Inc., (Allen, Tex.). The sensor...

    A direct link between the size of particles and their potential for causing health problems is what has the U.S. Environmental Protection Agency (EPA; Washington, D.C.; concerned about particulate matter (PM) that is 10µm in diameter or smaller. Renewed concerns have prompted the chemical process industries (CPI) to seek out more efficient dust-control systems that can handle...
February 1, 2006
Last month, Agilent Technologies, Inc. (Palo Alto, Calif.; launched the 1200 Series liquid chromatography (LC) system, replacing its predecessor, the 1100 Series LC. With more than 60 instrument modules available, the...
