Improving Absorption Measurements through Light Source Selection

| Contributed by Ocean Optics

In this Application Note, we show the impact of stray light on absorbance levels and describe how optimizing the choice of light source can minimize stray light and increase the maximum absorbance measured.

Analysis of THC and an Extended Metabolite Suite from Oral Fluid

| Contributed by Biotage

This application note describes effective and efficient ISOLUTE SLE+ protocols optimized for sample loading volumes of either 300 μL or 800 μL.

Pain Management Testing Upgraded

| Contributed by Phenomenex

Combine novel sample preparation and core-shell HPLC/UHPLC solutions for fast, highly sensitive and reliable performance.

NEW Kinetex Biphenyl Core-Shell Technology

| Contributed by Phenomenex

Transform reversed phase separations with this new, high powered orthogonal selectivity to traditional C18 phases that displays core-shell benefits including better resolution, higher efficiency, sharper peaks, and greater sensitivity.

GPC/SEC-Light scattering for starch analysis

| Contributed by PSS

The study of native starches from different natural sources shows that GPC/SEC-MALLS can be used efficiently to perform molecular characterization and degradation monitoring.

Automation of AOAC 988.13 for the Identification of FD&C Color Additives in Foods using Solid Phase Extraction

| Contributed by Gilson

In this application, AOAC method 988.13 was automated using a Gilson GX-274 ASPEC to perform the SPE process just prior to automated spectrum analysis using the Agilent 8453 UV-visible Spectrophotometer with the Agilent 8-position Multicell Transport.

Selective Extraction and Cleanup of Patulin Mycotoxin from Apple Juice Samples

| Contributed by Supelco

In this application, the use of SupelMIP SPE – Patulin is demonstrated for the cleanup of patulin in apple juice.
