A Thulium-based, higher precision X-ray analysis technique is suitable for assaying nickel in ore. Currently, production criteria is controlled using quantitative X-ray analysis with a chemical assay reference method (Wet Chemical DMG), which tests the ultimate purity of the nickel ore or concentrate. The current X-ray technique, however, has proven to have accuracy limitations resulting in the loss of potential revenue that can be realised from production. Moreover, the chemical DMG method is relatively expensive, complex and time consuming with the chemicals being dangerous to operators.
The TracerturboSD handheld X-ray fluorescence (XRF) instrument uses a silicon drift detector (SDD) for improved speed, sensitivity and resolution. Bruker’s XFlash SDD, previously available only in high-performance laboratory XRF instruments, now offers speed and analytical specificity when integrated into the handheld TracerturboSD.
The Lux line of polysaccharide-based columns is suitable for the identification and resolution of enantiomers. Lux columns are offered with two chiral stationary phases (CSPs), both of which use coated derivatised cellulose as the chiral selector. The two phases combine to create a dependable screening set with a wide range of selectivity. The Lux line is based on chiral technology that Phenomenex acquired along with the company Sepaserve.
PerkinElmer has released a Universal Attenuated Total Reflection (ATR) polarisation accessory, designed to offer users the benefits of combining infrared spectroscopy with a polariser. Polarised measurements provide additional information on the molecular structure of a sample, particularly the crystal or molecular orientation, and help in the accurate characterisation of materials.
Rigaku has launched the Desktop Minstrel UV, a fully automated UV imaging and protein crystal monitoring system. The instrument uses UV fluorescence microscopy to successfully monitor crystal growth by distinguishing protein crystals from non-protein crystals, such as salt.
