Column efficiency is a balance of trying to run your methods at a fast speed, without compromising separation quality. When an HPLC analysis is run quickly, you have more time Continue Reading
PFAS Analysis Workflow: Are you ready to take on UCMR 5 demand?
Every five years, the Safe Drinking Water Act (SDWA) requires EPA to issue a list of priority unregulated contaminants to be monitored by certain public water systems serving between 3,300 Continue Reading
Monitoring Human Exposure to PFAS
Introduction As the PFAS story continues, it is becoming widely recognized that drinking water isnot the only source by which humans can be exposed and suffer the effects of harmful Continue Reading
All About Performing GC Column Bake Outs
It is very important for GC users to know how to preserve the GC columns. Proper preservation not only helps in ensuring accurate results, but it also saves you money Continue Reading
Choosing the Right HPLC Column for LC-MS
Mass spectrometry (MS) is one of the most popular detection techniques for liquid chromatography (LC). It is also a technique that is not compatible with many of the mobile phase Continue Reading
Troubleshooting GC Column Problems
Although we wish our GC column would always perform perfectly, there are times when issues rear their ugly heads. When this happens, it can be difficult to know what the Continue Reading
