Measurement of electrophoretic mobility of coated nanoparticles using EAF4
In this application note, the electrical asymmetrical flow FFF (EAF4) system was used to measure the electrophoretic mobility and zeta potential of 50 nm Ag nanoparticles (AgNPs) coated with three different coating materials, namely citrate, polyvinyl pyrrolidone (PVP) and tannic acid.

Using a semi-preparative reversed phase HPLC column on Biotage Selekt
In this application note, Biotage shows the separation of a four-component mixture using a semi-preparative, slurry-packed reversed phase HPLC column with 15 um spherical silica particles and a Biotage Selekt instrument.

Using a semi-preparative normal phase HPLC column on Biotage Selekt
In this note, Biotage shows the separation of a three-component mixture using a semi-preparative slurry-packed HPLC column with 15 um spherical silica particles and a Biotage Selekt instrument.

Evaluation of matrix component removal using novel flow-through scavenging plates or columns for drugs of abuse testing in urine
This poster evaluates the extraction of a range of drugs of abuse from hydrolyzed and non-hydrolyzed urine using a novel flow through scavenging product, ISOLUTE HYDRO DME+.

Extraction of illicit and prescribed drugs from enzyme-hydrolyzed urine using ISOLUTE HYDRO DME+ prior to UPLC-MS-MS analysis

Evaluation of sample preparation approaches for the extraction of amphetamine, methamphetamine, MDMA and metabolites from urine prior to GC/MS analysis
This poster demonstrates a range of approaches for the extraction and cleanup of amphetamine, methamphetamine, MDMA and metabolites from urine. Each technique demonstrates the required method performance. Streamlined approaches are presented in order to save time, cost, solvent/reagent use and associated waste disposal all of which add to the overall assay costs.

Alternative forensic matrices: evaluation of simplified workflow for drugs of abuse extraction from nail samples prior to LC-MS-MS analysis
This poster aims to demonstrate workflow advantages for fingernail analysis; multi-sample homogenization, extraction and analysis for a range of drugs of abuse. A total of 24 drugs were analyzed.
