Gallium-68 (68Ga, t1/2 ¼ 67.8 min) owns great potential in nuclear medicine being extensively used in labelling of biomolecules like somatostatin and PSMA inhibitor analogues. 68Ga decay to stable Zinc-68 (68Zn) nuclide via electron capture (11%) and positron decay (89%)...

With the mounting interest in hemp and cannabis products for medicinal and recreational use around the world, the need for suitable analytical methods to identify and determine the concentration of cannabinoids is essential for ensuring consumer safety. Traditional analyses for...

Mephedrone (4-methylmethcathinone) is a synthetic cathinone derivative which has a similar chemical structure and effects to other stimulant recreational drugs such as amphetamine. Mephedrone was first introduced to the United Kingdom recreational drug market in the years 2007-2008 and has...

Chlorine sanitizers used in washing fresh and fresh-cut produce can lead to generation of disinfection by-products (DBPs) that are harmful to human health. Monitoring of DBPs is necessary to protect food safety but comprehensive analytical methods have been lacking. In...

In a recent paper published in Drug Testing and Analysis (Richard Bade et al., (doi: 10.1002/dta.2484)), UCT’s Xtract® solid phase extraction sorbent was used to extract a diverse range of new psychoactive substances (NPS) from samples of waste water. The...

In a recent study by Guillermo Alberto Keller et al., published in Journal of Opioid Management (http://www.wmpllc.org/ojs-2.4.2/index.php/jom), UCT’s Clean Screen® DAU was used to extract Propoxyphene (DPX)  and norpropoxyphene (NPX) from human plasma and analyzed by GC-MS. Plasma samples (500...

The neuromuscular junction (NMJ) involves a complex structure whose function is to convey action potentials from the motoneuron (MN) to skeletal muscle, resulting in stimulated contraction of the muscle. Studies have shown that the functionality and maintenance of neuromuscular synapses...

In a recent paper authored by Meena K. Yadav et al., published in Environmental Science and Pollution Research (https://doi.org/10.1007/s11356-018-2464-6), UCT’s XtrackT® solid phase extraction sorbent (XRDAH506) was employed in a validated method to isolate several illicit drugs from urban waste...

In a recent paper published in Food Chemistry by Claudio Alister et al., (oi: https://doi.org/10.1016/ j.foodchem.2018.06.090), A UCT’s QuEChERS blend containing 4 g magnesium sulfate (MgSO4), 0.5 g of disodium citrate (C6H6Na2O7), 0.5 g of trisodium citrate (Na3C6H5O7) and 1...

In a recent article published in Lab on a Chip, authors Donghee Lee et al., (DOI: 10.1039/C8LC00320C), used UCT’s specialty chemical (Tridecafluoro-1, 1, 2, 2-Tetrahydrooctyl)-1- Trichlorosilane (T2492-KG) in a mold-making process. This involved the production of a microfluidic cell compression...
