Tobacco and alcohol use during pregnancy is a serious public health concern, resulting in adverse obstetrical and neonatal outcomes including miscarriage, preeclampsia, low birth weight, preterm delivery, fetal growth restriction, decreased head circumference, placenta abruption, and facial abnormalities. Fetal alcohol...

In a presentation given at TIAFT 2018 (P277) by M.F.Fogerty et al., the development and optimization of a method for the following compounds was presented: fentanyl, norfentanyl, furanylfentanyl, butyrylfentanyl, methoxyacetylfentanyl, despropionylfentanyl, tetrahydrofuranylfentanyl, fluoro-isobutyrylfentanyl (FIBF), acrylfentanyl, para-fluorofentanyl, ortho-fluorofentanyl, carfentanil, α-methylfentanyl, β-methylfentanyl,...

While these compounds have been major players in a toxicological setting for quite some time, there still appears to be a generalized struggle to precipitate and extract them efficiently from whole blood. Not only is the ratio of acetonitrile to...

UCT has been featured in a SelectScience article, “Update on Water Analysis Methods” with recent release of streamlined  EPA 1694 method: Analysis of Pharmaceuticals and Personal Care Products in Water. Check Us Out Here!  

UCT has consistently produced high quality and reproducible organosilicon products.  That commitment was ensured through rigorous manufacturing and quality assurance programs.  Today we are pleased to announce that the system’s upon which our quality is based have been rewarded.  We...

Different sorbents were deposited on dispersive solid-phase extraction silica.  Poly (methyloctadecylsiloxane) (PMODS), poly (methyloctylsiloxane) (PMOS), aminopropyl-terminated poly(dimethylsiloxane) (APPS) and a copolymer of (52 – 48%) dimethyl-(48 – 52%) methylphenyl-siloxane (DMMPS).  The PMODS, PMOS and APPS materials were obtained from UCT...

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...

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...

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...
