A network that brings together over 60 leading Australian researchers who advance cutting-edge fluorescence technologies has been launched at Macquarie University.
The Avantes range of products in the field of flexible and modular spectrosopic solutions and fibre optic applications includes miniature spectrometer systems for online measurements and analysis; usually consisting of a light source, fibre optic cables, probes and a spectro-meter.
Traditionally if scientists wanted to look at something small they would put a sample under a microscope but now researchers have managed to shrink the microscope itself to the size of a single human cell.
Hydrophilic interaction chromatography (HILIC) is suitable for separating and retaining very polar compounds that do not retain or have very limited retention on traditional reversed-phase packings. HILIC columns retain highly polar compounds with only small amounts of water in the mobile phase. These more volatile mobile phases increase sensitivity with LC/MS applications. Water is used as the strong solvent so increasing water content will elute peaks faster.
Varian has expanded its FactorFour series of capillary gas chromatography (GC) columns with the VF-5ht for high temperature analysis, and the 0.15 mm ID columns for high-speed productivity. The entire FactorFour line, now comprised of nine phases for various environmental and industrial applications, offers a very low bleed specification.
