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.

Identifying the unknown PFAS profile in firefighting foams/AFFF

According to a recent study from Harvard University, the US EPA, and NIEHS, traditional targeted analysis techniques poorly characterize the PFAS composition of contemporary PFAS-based firefighting foams, know as aqueous film-forming foams (AFFF).  Using the EPA 533 PFAS drinking water method for the analyte list, the researchers found that targeted mass spectrometry methods accounted for <1% of organic fluorine content.  This is important because it demonstrates that targeted analysis methods miss nearly all the PFAS compounds in modern AFFF mixtures, thus underestimating the risk to human health and the environment.

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...

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.

Maximize NPS analysis with accurate mass spectrometry

Maximize NPS analysis with accurate mass spectrometry

LC-MS/MS is a powerful analytical tool in forensic toxicology testing that can support a variety of testing regimes such as screening, confirmation and quantitative workflows. More specifically, analysis of NPS using LC-MS/MS provides many advantages, including the ability to reliably detect new drugs and their metabolites from a variety of biological matrices.

Unlock the benefits of nominal mass spectrometry for NPS analysis

Unlock the benefits of nominal mass spectrometry for NPS analysis

The development of analytical methods for the detection and quantitation of drugs and metabolites in a range of biological matrices is a challenging process. Forensic toxicology labs need a reproducible and reliable methodology to ensure the robustness of the data and the quality of the results. They also need robust and sensitive instrumentation that can detect drugs at trace levels with high specificity, especially when it comes to novel psychoactive substances (NPS), which can be difficult to monitor and control.

What has the Echo® MS system done for the pharma industry? (And don’t just take our word for it!)

What has the Echo® MS system done for the pharma industry? (And don’t just take our word for it!)

SCIEX was very proud to have an illustration of the Acoustic Ejection Mass Spectrometry (AEMS) technology that powers the Echo® MS system on the front cover of the Journal of the American Society for Mass Spectrometry in January 2023. The associated article—Ultrahigh-Throughput Intact Protein Analysis with Acoustic Ejection Mass Spectrometry—was co-authored by scientists from SCIEX and Merck.

Uncovering the Links Between Childhood Growth, Body Size, and a Woman’s Risk of Breast Cancer

Uncovering the Links Between Childhood Growth, Body Size, and a Woman’s Risk of Breast Cancer

Welcome to the second in a series of posts marking International Women’s Day, and our ongoing support of World Cancer Research Fund. This installment is a review by Dr. Jennifer Baker, of her work, that, with the help of a WCRF grant, is studying body size and its links to breast cancer. Dr. Baker, Lead Investigator at Denmark’s Frederiksberg Hospital, has a Ph.D. in Human Nutrition from Cornell University. Her research focuses on clinical epidemiology.

Data Independent Acquisition Mass Spectrometry with the Power of SWATH

Data Independent Acquisition Mass Spectrometry with the Power of SWATH

There are many different methods in use today to acquire data on a mass spectrometer, but few have generated as much buzz in recent years as SWATH technology. First reported 5 years ago by Ruedi Aebersold and his group1, SWATH® Acquisition on a TripleTOF® instrument has rapidly become one of the premier acquisition strategies for identification and quantitation of complex samples. But what exactly is SWATH and why is it so powerful? In order to answer these questions, let’s first take a step back and look at the larger picture.

Vice President Biden Announces Agreement Naming Children’s Medical Research Institute’s ProCan Lab to the ‘Cancer Moonshot’ Initiative

A key goal of the ‘Cancer Moonshot’ initiative is the advancement of precision medicine, with the goal of making more targeted therapies available to more cancer patients. And researchers believe that the time is right, with the new technological innovations, the new insight into the biology of cancer and big improvements in the handling of ‘big data.’

The History of Isotopic Labels for Quantitative Proteomics

The History of Isotopic Labels for Quantitative Proteomics

Proteomics has become a vital tool for biological scientists performing research on the healthy and diseased states of living things. It involves the large scale and systematic analysis of all proteins within a given cell, tissue, or organism. Because proteins are regulated by many different internal and external stimuli, the proteome is dynamic and quantities of proteins can change from one state to the next. Therefore, in order to be of the highest utility, proteomics experiments need to both identify and quantify proteins so that comparative studies can be done, such as between healthy cells and tumor cells, or the comparison of different treatment regimens.

The Promise of Precision Medicine

Here is the latest update on the Worldwide Efforts to Accelerate Precision Medicine

The NIH recently issued a press release in early July announcing $55 million in awards. According to the release, the $55 million award in the fiscal year 2016 will go towards building the foundational partnerships and infrastructure needed to launch the Cohort Program of President Obama’s Precision Medicine Initiative (PMI). The PMI Cohort Program is a landmark longitudinal research effort that aims to engage 1 million or more U.S. participants to improve the ability to prevent and treat disease based on individual differences in lifestyle, environment, and genetics.

Why Study Lipids?

Why Study Lipids?

I had an opportunity to follow up with Steven M Watkins, Ph.D. to talk about the importance of studying lipids in disease. Steve has been working in the lipids field for over 20 years and is one of the foremost experts in lipid biology. Steve founded Lipomics in 2000, an early metabolomics company focused on quantitative lipidomics and had followed that company through a series of changes that led to its involvement in the clinical diagnostic development and global metabolomics. Steve authored over 70 peer-reviewed publications including several book chapters on lipids and lipid metabolism. His presentations on this topic are fascinating and very informative, so I wanted to capture some of his thinking here!
