A newly launched gas chromatography (GC) device from Analytical Pixels Technology (APIX; Grenoble, France;, 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...

Detection of extremely small quantities of dangerous or hazardous substances is important in many areas, including national security, safety of public utilities and radiation prevention. Several analytical methods have been developed using structural, functional and electronic properties of nanomaterials. In particular, noble-metal quantum clusters (QCs), a family of nanomolecules exhibiting intense...

A research team from the Institute for Photonics and Advanced Sensing, and the School of Chemistry and Physics, the University of Adelaide, South Australia ( 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...
February 1, 2012
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...
