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…

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…

Continuing on from last week with the gummy bear sample preparations, I decided to take a look at the different things in that gummy bear. The gummy bear in question is a multivitamin that contains a multitude of different vitamins, so I decided to first focus on Vitamin C or Ascorbic Acid. Preparing the sample…

With gummy candies becoming more common as a matrix for things like cannabinoids and multivitamins, it’s important to have a simple, fast, and repeatable sample preparation in order to obtain reliable values for analytes of interest in these gummies. I started with a multivitamin fiber gummy, and I thought to myself, how do I get…

When we first began designing the Lucidity GAS we realized that it was important for the GC and the GAS to be in constant contact with a two way dialogue and to know exactly what each other were doing for maximum safety and minimum gas consumption. If your gas chromatograph is informing your gas generator…
