The aldehyde-coated slides were prepared by adding glass slides to a 2 mM of UCT PSX1050 in toluene for 4 hours.  The slides were removed from the solution, rinsed with toluene and dried in nitrogen.  Solutions of lectin were prepared...

The article, titled “Validation of a streamlined multiclass, multiresidue method for determination of veterinary drug residues in bovine muscle by liquid chromatography-tandem mass spectrometry” (DOI: 10.1007/s00216-014-8386-3) uses a d-SPE technique for the extraction of 131 veterinary drug residues in bovine muscle...

In the method the authors used UCT’s CLEAN SCREEN® THC solid phase extraction (SPE) cartridges for the extraction of the cannabinoid metabolites from urine samples.  The SPE extractions helped researchers achieve LOD’s ranging from 0.1 to 1ng/mL, matrix effects biases ranging...

This technique requires multiple extractions at 2 different sample pHs and consumes large amounts of organic solvents. EPA method 625.1, an updated version of method 625 has been recently published (by Lemuel Walker, Office of Science and Technology, US EPA)...

In the method the authors used a UCT Selectra® PFPP HPLC column for the analysis.  The unique phase provided the researches with the selectivity they needed with excellent peak shape and run times.  The LOQ’s for all compounds examined were 0.2µg/mL,...

Model poly(dimethylsiloxane) networks were obtained by a hydrosilylation reaction, based on the addition of hydrogen silanes from cross-linker molecules to end vinyl groups present in prepolymer molecules. UCT Specialties materials including a difunctional prepolymer, a,u-divinyl poly(dimethylsiloxane) and mixtures of two...
