Determination of Stevioside and Rebaudioside A in Stevia leaves, beverages and food additives using HPTLC-MS

HPTLC-MS was used to analyze stevioside and rebaudioside in artificial sweeteners, stevia plants, cola and isotonic drinks with a minimum of sample preparation.

Solid Phase Extraction: Reversed-Phase Methodology

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.

High-Performance Quantitative H-1 NMR

The signal ratio of two different protons can be measured with tremendous precision, which enables the generation of certified reference materials for use as qNMR standards.

Analysis of Tetrahydrocannabinol (THC) and Carboxytetrahydrocannabinol (THCCOOH) in Surface Waters by SPME and GC/MS

Rapid Determination of Protein Binding Affinity Using Solid Phase Microextraction

Accurate protein binding affinities were measured using bioSPME more rapidly than membrane dialysis (RED) techniques. Binding affinities correlated to the reference values.

Tetrakis(dimethylamino)ethylene (TDAE)

In 2001, Professor William Dolbier, Jr., at the University of Florida reported1 an approach to nucleophilic trifluoromethylation based on the generation of a trifluoromethyl anion using CF3I in the presence of a powerful twoelectron reductant, tetrakis(dimethylamino)ethylene (TDAE)

Trichloroacetimidate Reagents

Trichloroacetimidates are also commonly employed as alcohol alkylation reagents, particularly when existing functionality is not acid sensitive.

The Best Approaches to Gas Purification

Ultra-Pure MALDI Matrices

One of the most important aspects of our ultra-pure MALDI matrix substances is their ability to dissolve rapidly and completely; a brief vortex mixing is typically sufficient.

Resolving by Mass

Determination of Phospholipid Oxidation by UV/VIS Spectroscopy - Avanti® Polar Lipids

The percent oxidation of a phospholipid can be determined by using Beer’s Law to calculate the peroxidized phospholipid’s concentration from its absorbance at 234 nm.

Bind/Elute vs Flowthrough Mode in Multimodal Chromatography

This page describes the difference between bind/elute and ﬂowthrough modes in multimodal chromatography using Cytiva products.

Ascentis® Express C8 U/HPLC Columns

When a C18 doesn′t give the desired separation, or your sample contains compounds that are known to be difficult to retain or resolve on a C18, consider changing to an Ascentis® Express C8 column.

Reductive amination with 2-picoline-borane complex

2-picoline-borane (pic-BH3) is an excellent alternative reagent for reductive aminations.
