Rapid Measurement of Major, Minor and Trace Levels in Soils Using the Varian 730-ES
Simultaneous ICP-OES (inductively coupled plasma-optical emission spectroscopy) has become a widely used technique for reporting the health of soils in the agricultural industry since it provides fast, accurate and precise determination of elements in agricultural soil. This work describes the preparation and analysis of certified reference soil materials using the Varian 730-ES simultaneous ICP-OES with CCD (charge couple device) detection. The Varian 730-ES includes a switching valve system that improves the efficiency of sample introduction and washout, providing greater sample throughput
and accuracy.

High-Resolution Analysis of Tricyclic Antidepressants and Benzodiazepines Using Pursuit® XRs C18 Columns
More than 80% of chemical analyses in the pharmaceutical industry are done using HPLC (high pressure liquid chromatography) columns. Analytical Research and Development (AR&D) laboratories in pharmaceutical companies are constantly challenged for time when developing robust analytical methods. Varian scientists have developed a family of HPLC columns, Pursuit XRs, for resolving complex and challenging samples in the pharmaceutical industry that will improve AR&D laboratory productivity. This article demonstrates the extended resolution capabilities of
Pursuit XRs C18 columns with a 14-component mixture of tricyclic antidepressants and benzodiazepines, and compares it to benchmarked C18 HPLC columns.

Purification of RNA Oligonucleotides Using 96-Well TOP™ (Trityl-on Cartridge Purification) Plates
Due to the increased hydrophilicity and pH instability of RNA oligonucleotides compared to DNA oligos, RNA oligonucleotide purification methods often require modification from standard DNA methods for optimum purity and yield results. In this application, purification of 2’-deprotected, 5’-DMT-on RNA oligonucleotides was examined using TOP 96-well oligonucleotide purification plates and on-column detritylation. The simple method, standard 96-well format, and gravity or vacuum purification option result in a high-throughput, high-purity
method for RNA oligonucleotide purification.

Improved Trichothecene Analysis for Food Testing Labs With Varian’s Bond Elut® Mycotoxin
A new application note highlights the use of Bond Elut Mycotoxin for superior trichothecene analysis. The single product delivers better clean up of food and grain samples for 12 trichothecenes (type A and type B), as well as zearalenone. Recoveries of polar toxins are not compromised as they are on competing charcoal/alumina products. Unlike immunoaffinity columns (IAC), which require a separate column for each toxin, Bond Elut Mycotoxin provides great results with one product and one method
