A newly launched gas chromatography (GC) device from Analytical Pixels Technology (APIX; Grenoble, France; www.apixtechnology.com), called GCAP, uses a nanoscale silicon-beam resonator to detect mass. A piezoelectric cross-beam initiates the vibration of the nanoscale silicon resonator, and the resonance frequency varies with the mass in contact with the silicon resonator. Because GCAP’s architecture...

A new particle-size measurement technique has been developed and used to evaluate filter retention efficiency for particles with an average diameter of 12 nm by C.T. Associates Inc. (Eden Prairie, Minn.; www.ctassociatesinc.com) and W.L. Gore and Associates (Newark, Del.; www.gore.com). Scientists at C.T. Associates developed the liquid nanoparticle sizer (LNS) for evaluating filtration devices that remove...

A research team from the Institute for Photonics and Advanced Sensing, and the School of Chemistry and Physics, the University of Adelaide, South Australia (www.adelaide.edu.au) has combined suspended-core microstructured optical fibers (MOFs) with photoinduced electron transfer (PET) to demonstrate a new type of fluorescent optical fiber-dip sensor for small volume ion detection. Led by professor Tanya...

Acidity is a critical parameter in the chemical process industries, and accurate measurements of pH can be important indicators for process quality control. A refreshed understanding of pH measurement can help to overcome process-specific challenges to measurement and to select the pH measurement devices that best meet the needs of the process. Further, a review of the temperature dependence of pH...
