Trazodone is a drug compound that was initially designed to treat depression and anxiety disorders but has also become widely used as a sleep aid. Because of its increasing popularity, we thought we would test it in our Lucidity LC-UV. It’s typically found in pill form in 25mg to 100mg pills. We got our hands…

Listen in as Prof Dan shows you what to do when peaks are coming out too close together in Gas Chromatography (GC) or Liquid Chromatography (HPLC). He gives some simple tips that can help better separate the peaks so you can better identify and quantify different compounds present in a sample.
While eating breakfast with my kid, they asked me about the dyes in the cereal. That got me thinking about the different dyes in food and how these dyes were analyzed. I thought that a UV-Vis instrument would be the best choice. But, what about an HPLC with a UV detector? I figured a UV…

Sometimes there’s a wrong way to do things and a right way to do things. In the case of preparing samples that are in tablet form, there’s a correct way and an incorrect way. Take a look at this video to see what we’re talking about. HR Rick is less than happy about it being…

Amino acids are the building blocks of life. Every living thing uses amino acids to build the proteins needed to do various functions within the organism. Where do amino acids come from and how many are needed to function? For humans, there are a total of 20 amino acids that are necessary for your body…

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.
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).
Folic Acid, Folate, or Vitamin B9 is a key vitamin used by the human body to generate new healthy red blood cells, form DNA and RNA, and break down a certain amino acid, homocysteine, that can be harmful in high amounts. The need for Folic Acid is especially important during pregnancy, which is why there…

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…

HPLC columns are the crux of a good separation and as we all learned, the smaller the particle size, the higher the efficiency of the column, and the better resolution you will get. This better resolution leads to more peaks being separated out or even close eluting peaks to be baseline resolved. With smaller particle…
