Designed for Speed: Fast GC

May 6, 2022

Even the best-trained experts can only move as fast as their equipment will allow, and as helium prices increase and supplies drop, the fast spectral acquisition speeds of GC-TOFMS instruments stand ready to reap the benefits of fast GC separations afforded by utilizing hydrogen carrier gas.

While the advantages of helium as a carrier gas for mass spectrometers have long been known, it is a limited natural resource. On the other hand, hydrogen gas generators can be installed in any lab for a constant supply and, conveniently, increased chromatographic speeds.

Ferroalloy Factors: Oxygen and Nitrogen Determination

March 18, 2022

Most iron products these days are improved with the addition of ferroalloys, or iron alloys containing high levels of other primary elements. Ferroalloys are everywhere from cast iron to stainless steel. These extra elements help strengthen the metal by adding their own characteristics: silicon is used to deoxidize steel, manganese mitigates harmful effects of sulfur, and chromium increases corrosion resistance, to name just a few. But adding to iron is not without risk; if unwanted elements are part of the ferroalloy, they can weaken the resulting products.

Calming Crude Oil with the CHN828

March 11, 2022

The price of crude oil is one of the great drivers of our economy. At a minimum, the price of all goods includes costs of transporting them from manufacturer to consumer. But the price of crude oil and other oil materials can feel fickle, increasing and decreasing with supply or demand or even just market sentiment. Natural disasters or humanitarian crises can drastically impact availability or demand, sending prices hurtling skyward or crashing down. No refinery can control the entire market. All a refinery can do is operate their facilities in the most efficient and optimized manner. Doing that, however, requires an accurate way to monitor their process.

Fatal Fakes: The Counterfeit Drug Crisis

January 21, 2022

Prince. Tom Petty. Michael K. Williams. Lil Peep. Logan Williams. Daniel Mickelson. Jay Bennett. Bobby Brown Jr. The list of celebrities lost to fentanyl overdoses is long and growing alarmingly fast year after year. But it's not just celebrities falling victim to this potent drug. On January 13, 2022, a 13-year-old at the Sport and Medical Sciences Academy in Hartford, Connecticut, was exposed to a lethal dose of fentanyl and died three days later. In 2016, fentanyl surpassed even heroin as the deadliest opioid. But why?

Beneath the Peel: Characterizing Citrus Aromas with GC-TOFMS

August 6, 2021

Both lemons and limes have strong citrus odors, but the difference between these fruits is wide at an analyte level. Identifying these differences is not as easy as it first seems, but the Pegasus® BT and the automated data processing software included in its ChromaTOF® brand software make finding the peaks easy.
