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.
Vitamin C is a water soluble, key nutrient found in fruits, vegetables and berries. Unlike many animals, humans cannot synthesize their own vitamin C and must get it from their diets. One way to supplement the intake of vitamin C would be to take a vitamin. I decided to test 3 different vitamins for vitamin…

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…

It seemed like a great idea to ship a chemist out with each GC-FID or LC-UV until they started flying off the shelves. Now we’re concerned we’re gonna run out of chemists. But there’s nothing better than having a “chemist in a box” along with your analytical system to help walk you through setup, operation,…

Your favorite Dans are being packed up and sent to New Orleans! They’re a little late for Mardi Gras, but they’re just in time for the National Spring meeting of the American Chemical Society (ACS) in New Orleans from March 17-21, where the theme is Many Flavors of Chemistry. Catch up with them during the…

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).
Chemist Dan shows you how to perform dilutions in the chemistry lab, which is an important pre analysis step for preparing samples and standards for GC or U/HPLC analysis.
It only seems appropriate during cold and flu season that we do something on soaps and hand sanitizers, and interestingly enough, we have some customers who are analyzing exactly that. One of the active ingredients our customers are looking for is BZK (Benzalkonium chloride), also known as BAC, BKC, and BAK. BZK is an antimicrobial…
