GC Column installation VideoGC Column installation Video | Quick Guide
A properly installed GC column is the most important beginning for your work. This 5 minute Quick Guide video demonstrates how to properly install a GC column, giving you great chromatography, analysis after analysis.

HPLC - Troubleshooting Changes in Selectivity Retention & ResolutionHPLC - Troubleshooting Changes in Selectivity Retention & Resolution | Troubleshooting Guide
Everything about your chromatogram has changed and you just don’t know why. The peaks have different retention times, peaks that are normally well resolved are now co-eluting, and the selectivity of all of the peaks has been altered. Taking one of these problems at a time is challenging, let alone all three! However, help is at hand...

How to choose an HPLC ColumnHow to choose an HPLC Column | Quick Guide
Some great general hints and tips for HPLC column selection.
Read the literature. It is very rare that a separation has never been performed before and so checking the literature, refereed journals... Run a generic method. So you have read the literature and still have not found a separation...

GC - Troubleshooting Guide to Broad Peaks and Loss of MS SensitivityGC - Troubleshooting Guide to Broad Peaks and Loss of MS Sensitivity | Troubleshooting Guide
A GC-MS method which normally works well starts to exhibit broad peaks and there is a loss in sensitivity, what could possibly be causing the problem? Column contamination, an air leak, incorrect oven temperature, the list could be lengthy..

HPLC Techniques in Biopharmaceutical Analysis l Live Webcast
Thursday 21st August 2014, 8:00am PDT / 11:00am EDT / 16:00 BST / 17:00 CEST

HPLC Techniques in Biopharmaceutical AnalysisThe enhanced complexity and variability that comes from the size of biopharmaceuticals, allied with the intricacy of the production process, mean chromatography is employed to a much greater extent during production and release testing.
This Essential Guide webcast will provide details of why differing modes of chromatography are required in the research, preparation and analysis of biopharmaceuticals and when they would be typically used.

Automated Inline Sample Preparation for Ion Chromatography l On Demand Webcast
Thursday 24th July 2014, 8:00am PDT / 11:00am EDT / 16:00 BST / 17:00 CEST

Automated Inline Sample Preparation for Ion ChromatographyIndustrial chemicals such as organic and mineral acids and organic solvents play a pivotal role in many processes. Their purity and the profile of impurities can be critical to the success or failure of a manufacturing facility. Here we will show automated inline sample preparation techniques for determining ionic impurities in a variety of important products. Brief examples of many types of treatment protocols will be described and the results shown.
