GC Analysis of Class 2 Residual Solvents on OVI-G43
GC Analysis of Class 2 Residual Solvents on OVI-G43
Analysis of Residual Solvents in Hemp Extract by Headspace SPME-GC/MS
The use of solid phase microextraction (SPME) allowed for the straightforward, fast, sensitive, and accurate GC/MS determination of the residual solvent content of spiked and unspiked samples of hemp extract.
Solid Phase Extraction: Normal Phase Methodology
Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
LC/MS Analysis of Phospholipids in Milk on Ascentis® Express HILIC after SPE using Supelclean Si, Shotgun HPLC Analysis
(soybean), ≥97%; L-α-Phosphatidylethanolamine from egg yolk, Type III, ≥97% (TLC), lyophilized powder; L-α-Phosphatidylcholine, from egg yolk, Type XVI-E, ≥99% (TLC), lyophilized powder; Sphingomyelin, from chicken egg yolk, ≥95%
Catalytic Amide Bond Formation Protocol
Information on the Amide bond and the Catalytic Amide Bond Formation Protocol. Amidation of amines and alcohols. The amide bond, an important linkage in organic chemistry, is a key functional group in peptides, polymers, and many natural products and pharmaceuticals.

Residual Analysis Optimized for Static Headspace GC Applications
Static headspace GC (GC-SH) is a technique used to concentrate volatile analytes prior to analysis. It can improve detection of low level volatile analytes and minimizes matrix interference by eliminating the need to inject the sample directly.
Clinical Application of SPME: Analysis of VOCs in Exhaled Breath as Cancer Biomarkers
This report demonstrates the potential of solid phase microextraction as a clinical research tool for the extraction of VOCs associated with lung cancer from human breath.
Peptide Resin Loading Protocols
Protocols for loading various peptide resins
acrylamide in food
Acrylamide analysis has been a very hot topic since the chemical was identified in food in 2002 by researchers at the Swedish National Food Administration.

Fast Extraction and Low Level Detection of Chloramphenicol in Shrimp
A highly selective and sensitive analytical method was developed for chloramphenicol using a QuEChERS type sample preparation approach and LC-MS/MS detection.
SLAP Reagents for Piperazine Synthesis
The Bode group has developed SnAP (stannyl amine protocol) reagents that cross-couple with aldehydes and ketones to provide one-step access to a wide variety of saturated N-heterocycles.
Removal of Detergents from Biological Product Matrices
The Amberlite™ XAD-4 resin used in Porozorb™ cartridges is a proven technology that is highly effective in removing various detergents from cell culture media for biopharmaceutical applications such as vaccine production.
Preparation, Uncertainty, and Certification of Ethanol Standards
Ethanol standards are widely used in forensic and toxicology applications for determination of blood alcohol content. Results of blood alcohol testing have significant legal implications and are frequently used as evidence in courts of law. The blood alcohol analysis process...
Analysis of Human Plasma Lipids Using sub-2 μM C18 UHPLC Column with MS Detection
