Back to the new basics: Part 1 | Making the leap from GC-MS to LC-MS

Producing accurate results quickly in a demanding environment is no easy feat for analytical scientists. What’s more, many of us are constantly questioning ourselves—I certainly am—about whether we are employing the best technique for the analysis at hand.

It’s an overwhelming thought, considering the wide range of tools that are available to choose from, each of which offers varying levels of capacity, sensitivity, selectivity, specificity and cost. How do you meet the unique needs of your organization without breaking the bank? I get it, and I’m not here to convince you it’s easy. My aim is to guide you through the process to help you make the right decision for you.

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.

Full, partial and empty capsid ratios for AAV analysis: What’s the big deal?

Full, partial and empty capsid ratios for AAV analysis: What’s the big deal?

For many of you working to develop gene therapy drugs, you know that the time to market the drug is critical. Because gene therapeutics cure diseases by targeting specific genes, it is a constant race to see who develops the drug first. Unlike other classes of drugs where multiple medications can be used to treat a disease, whoever is first to develop a gene therapy drug wins.
