This video walks you through System Suitability, which tests your Liquid Chromatograph (HPLC) or Gas Chromatograph (GC) to help you ensure that your system is functioning properly and giving good results.
Solvents are used extensively in labs and chemical manufacturing as starting materials for a chemical process; the diluent for a product, starting material, or reaction; or in the analysis of a starting material or product for quality purposes. Often times after use, that solvent is then sent into a waste stream to be dealt with…

Join Prof Dan as he explains what an FID (Flame Ionization Detector) is. Other than Mass Spec, FID is the most common type of detector used in a GC (Gas Chromatograph). Imagine blowing a stream of chemicals into a candle then measuring the amount of static electricity, and you’ll get a rough idea of how…

Now that spring is here and all things pollen are happening it’s time to get the allergy medicine ready. In honor of this wondrous time of year, we thought we would test some allergy meds! While not the usual way to test these medications, I decided to see if I could test using the Lucidity…

Prof Dan explains briefly and simply what Limit of Detection and Limit of Quantitation mean, two concepts and terms that are important to understand when preforming chemical analysis with techniques like Gas Chromatography (GC) and Liquid Chromatography (HPLC).
Professor Dan explains how much sample you should put in your Gas Chromatograph (GC), and how to adjust the amount of sample you’re putting in
Whether you drink a beer from a major manufacturer, the local brewer down the street, or even brew the beer yourself, knowing the ethanol content of that beer is an important piece of information. Up until 1995 the alcohol content wasn’t allowed to be on beer labels at all until the Coors Brewing Company successfully…

Volatile organic compounds, or VOCs, is a term given to organic compounds that become a gas at ambient temperatures and pressures. These VOCs are monitored because many are hazardous to human health, with several being a carcinogen. The source of these VOCs are industrial processes, vehicle emissions, and even natural sources such as forest fires.…

Robustness is something that needs to be considered when using a Gas Chromatograph (GC) instrument. You want a system that is rugged and reliable and able to withstand dirty samples and long batch times, so that you don’t have to spend a lot of time troubleshooting, repairing, or cleaning your GC. After all, you’ve got…
