Newly published US EPA method 625.1 allows for solid phase extraction of semivolatile organic pollutants in industrial discharges

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)...

Selectra® PFPP Column Used in NIDA Paper Examining Cannabinoids in Oral Fluids

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,...

UCT Specialties Petrarch® Silanes and crosslinkers used in the study of the dynamic response of transiently trapped entanglements in polymer networks

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...

UCT Specialties Product A0700 (N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane) Used as Coating on Glass Coverslips to Aid in Growth of Mouse ES Cells

The presence of the A0700 on the glass coverslips provided an excellent environment for the growth of the cells.  The covering of the glass coverslips with A0700 also eliminates the adhesion of the growing cells to the glass coverslip. The...
