This application note describes the ultratrace determination of iodine-129 in aqueous samples using the 7700x ICP-MS with oxygen reaction mode.

This application note describes an effi cient and economical RTL-GC/FID method for determination of fatty acids in infant formulas. The fatty acids were converted to FAMEs using acetyl chloride-methanol methyl esterifi cation method. Agilent J&W HP-88 capillary GC column provides excellent separation for complex FAMEs including cis-trans isomer separation.

This document describes the enhanced analysis of semi-volatile compounds using sub-ambient ELSD and HPLC. Evaporative light scattering detection (ELSD) is a powerful tool that can detect any sample that is less volatile than the mobile phase in HPLC applications, regardless of the optical properties of the compounds. ELSD offers distinct advantages over conventional UV or DAD detection, especially for gradient separations. In order to maximize the detection of non-UV absorbing semi-volatile analytes, ELSD detectors need to operate at lower temperatures. Most ELSDs today can evaporate highly aqueous eluents at ambient temperature, but for low molecular weight, low boiling point compounds, ambient temperature is still too high and sensitivity is poor. Sub-ambient ELSD is required to improve the detection of these compounds. The Agilent 385-ELSD is specifically designed to operate under these demanding conditions. It features a Peltier cooled evaporation tube that provides sub-ambient ELS detection down to 10 °C. Dry nitrogen gas is added during the evaporation step to facilitate solvent removal at sub-ambient temperatures.

This is an application note about Agilent's Scout Scan technology, which describes how to use Scout Scan technology to lock samples without deuterium in NMR liquid spectroscopy

This application note describes the applications and experimental considerations for FastMAS and UltraFastMAS techniques. FastMAS and UltraFastMAS techniques enable experiments with rotation speeds of 40 to 65 kHz, which reduces linewidths and suppresses spin diffusion caused by proton-proton dipolar interactions. These techniques enable experiments such as direct proton observe or solid-state HETCOR to collect spectra comparable to those that formerly required both spinning and experimentally difficult multiple-pulse homonuclear decoupling sequences. Another advantage of FastMAS and UltraFastMAS techniques is that they suppress spin diffusion between protons, allowing experiments to be conveniently performed on individual protons in single or multiple dimensional experiments.

This application note describes the benefits of the Agilent 2100 bioanalyzer in real-time quantitative PCR (QPCR) experiments. The results show that the Agilent 2100 bioanalyzer is an indispensable tool to ensure experimental success by verifying RNA template quality prior to QPCR experiments and to improve the assay design and validation process by monitoring size and purity of the QPCR amplicons.

This application note shows the analysis of Aceton, n-Hexane, Methyl iso-Butyl Ketone (MIBK), Methyl iso-Butyl Carbinol (MIBC), and Methyl n-Butyl Ketone (MNBK, 2-Hexanone) using the Agilent 490 Micro GC.

Rapid analysis of pesticides in vegetables by Agilent 5975T LTM GC/MSD and TSP

This document discusses the assessment of the purity of frying fats using Agilent PLgel and gel permeation chromatography. The analysis involves the separation of oligomeric glycerides based on molecular size in solution, allowing for the separation of the major component (monoglyceride) from the minor components (diglyceride, triglyceride) of frying fat. Quantitative analysis can then be performed to obtain information about the purity of the monoglyceride.

This document describes the analysis of frying fat using Agilent PLgel columns and gel permeation chromatography. By separating compounds of different molecular sizes, the content of high molecular weight substances in fats can be determined, thereby evaluating the quality and properties of the fats.
