Fast and Simultaneous Analysis of Ethanol Metabolites and Barbiturates

While most analytes in forensic applications analyze well with positive ionization, there are analytes that show better ionization efficiency with negative ionization, for example, acidic compounds. These analytes include ethanol metabolites such as ethyl glucuronide (ETG), ethyl sulfate (ETS), and the barbiturates such as amobarbital, butabarbital, butalbital, pentobarbital, phenobarbital, and secobarbital.

It’s a Point and Click World with the X500B QTOF System for Biologics Characterization

The newly-designed SCIEX OS software interface brings to life fluid navigation and ease of use so you can keep moving forward on your scientific discoveries. In fact, it’s so simple to learn and operate that you and your team can be up and running faster than you might expect.

PPCP Detection in Drinkwater is no Match for the QTRAP® 5500

SCIEX is no stranger to drinking water analysis, and the Environmental Compendium once again addresses the topic in an application note which covers LC-MS/MS with Fast Polarity Switching.   Using the QTRAP® 5500, researchers were able to detect a large panel of Pharmaceuticals and Personal Care Products (PPCP’s) while performing fast positive/negative switching all from a single injection.  Method details go the distance in this application note, as five experiments were called into action for comparison.

From Extraction to Cleanup—Measuring Mycotoxins from Cornmeal Products

When we look at emerging food trends for this coming year, you may be surprised to find that the US cornmeal market is making headlines as it is set to grow at a compound annual growth rate (CAGR) of two percent by 20201. This is the type of news that excites us, scientists, as it reminds us why we test for things like mycotoxins in cornmeal and the impact such analysis has on farmers and food manufacturers.

Nitrosamines: Where are we now?

Nitrosamines: Where are we now?

Nitrosamines are a large group of N-nitroso compounds that share a common functional N-N=O group. They are produced by a chemical reaction between a nitrosating agent and a secondary or tertiary amine. Back in 2018, nitrosamines suddenly found themselves in the spotlight when they were unexpectedly detected in medications for high blood pressure. Since then, they have been found in several other prescription medications, including those for heartburn, acid reflux and diabetes, resulting in manufacturers recalling some common medications.
