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.
LC/MS/MS Method for Determination of Glyphosate, AMPA, and Glufosinate in Cereals
Glyphosate and related compounds are measured in oatmeal and infant cereal using ion-exchange polymer-based particles for HPLC and SPE. Low level detection was obtained.
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.
Derivatization and Separation of Aliphatic Amines
Derivatization of Aliphatic Amines - Results from the Supelco Ascentis Express column show higher peak resolution, and improved peak shapes than typical chromatograms.
Analysis of Tetrahydrocannabinol (THC) and Carboxytetrahydrocannabinol (THCCOOH) in Surface Waters by SPME and GC/MS
Analysis of Tetrahydrocannabinol (THC) and Carboxytetrahydrocannabinol (THCCOOH) in Surface Waters by SPME and GC/MS
Determination of l- and d-Lactic Acid Enantiomers by HPLC/MS/MS
Rapid, simple, reproducible chiral separation and quantification of L- and D-lactic acid enantiomers using Supelco’s Astec CHIROBIOTIC® R chiral column and tandem 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.

Securing a Traceable Supply Chain for Food Grade Flavor Ingredients
We presents a white paper on Securing a Traceable Supply Chain for Food Grade Flavor Ingredients.
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.
