Selecting an LC-MS system for quantitation of pharmaceutical drug development
We understand you are busy, needing to prioritize running instruments, reporting results and managing your laboratory to meet deadlines. We created a solution guide to explain how SCIEX systems fit in the drug development pipeline to save you time evaluating options.
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.
Guide decisions during cell line development with more information at the intact level
Monitoring product quality attributes (PQAs) throughout monoclonal antibody (mAb) development is vital to ensuring drug safety and efficacy. By adopting orthogonal analytical techniques and integrating new technologies that have the potential to provide more information, it is possible to improve product quality and manufacturing efficiency and make more informed decisions.
High complexity of the lipidome
The complexity of the lipidome is diverse in the structure and there are many combinatorial isoforms that are available within nature. Currently, many different techniques are required to fully characterize a lipid molecule. What if you could do it in a single...
Breaking down the SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready
Sensitivity and robustness carry different meanings in the world of mass spectrometry. Generally, sensitivity refers to an instrument’s ability to achieve lower limits of detection (LOD). Robustness, on the other hand, refers to an instrument’s ability to consistently...
The honey sting

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.
Purchasing Mass Spec Technology for Your Forensic Lab
What does every scientist think about in the lab? Validation. This is the feeling I encountered while reading a recent scientific report on nature.com. What struck me was not only the study itself which discounted cannabinoid incorporation into hair as a method for...
A Reliable Method for the Identification, Quantitation, and Confirmation of Pesticides
When carrying out routine pesticide identification tests in your lab how simple is the process of identification, quantitation, and final confirmation from sample to sample? A reliable method designed to generate multiple data sets and confirm sample data in parallel with your test can save an awful lot of time and effort which is especially helpful as the demand for routine testing increases. In this poster talk, Detlev Schleuder, Support Manager for Food & Environmental Markets, explains how the new QTRAP® 6500+ system can optimize your laboratory’s output with this simple method.
The Gluten Free Cookie Label Test
I am a label reader. I like to eat healthily and know what the long, confusing ingredients on the side of a package mean. Therefore, in the spirit of the holiday season, I dedicate this blog to all the gluten intolerant folks out there whose only wish is to eat a yummy cookie while also being absolutely positively sure it is gluten free.
Testing Liquor for Authenticity Using LC-MS/MS Technology
The Proof is in Your Holiday Drink If you think bootlegging was limited to the age of Prohibition then you have never tested liquor for authenticity using mass spectrometry. Maybe it is a scientist thing, but we simply cannot help but bring up the subject as people...

Thanksgiving Menu: A Detectable Feast!
On Thursday 26th November 2015, millions of households across the United States will sit down to a hearty traditional Thanksgiving meal. The Thanksgiving holiday is when people celebrate the blessings of the year, in particular the harvest.
Are there Antibiotics in your Thanksgiving Turkey?
Truth – the first turkey I ever cooked was still frozen when it hit our plates. I couldn’t figure out why that thing was taking so long to roast. Then it hit me. I forgot to defrost the bird. If I recall correctly, even the giblets were still in it. It was ten p.m. when I broke the news to my guests that the turkey was not happening. A pizza was ordered, and everyone breathed a sigh of relief that they would not be suffering from a bout of food poisoning.
Celebrate with a Pesticide Free Thanksgiving!
Before you start wondering if you should buy organic ingredients this Thanksgiving, it is good to know regulating bodies set and monitor allowable pesticide limits within our food supply. Pesticides that help control pests, disease, and deter unwanted animals from eating supplies found in fields, mills, and facilities. How and when this testing takes place in the United States is overseen by the Environmental Protection Agency (EPA) according to five primary regulating statutes.

Simultaneous Detection of Multiple Species in Meat Using LC-MS/MS Technology
Smart food shopping starts with labels. However, what if we told you the ingredient list may not be all that it seems? According to Food Safety News, producers are sneaking lower quality ingredients into our food to save money. This type of food fraud is estimated to cost the global food industry $10 to $15 billion per year. If you think back to the Middle Ages, even our ancestors were consumed with cost savings by inserting nutshells, seeds, berries, and more within their spices.
