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
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.
Adducts and N-oxides: understanding lipid nanoparticles (LNPs) for better mRNA drugs
Lipid nanoparticles (LNPs) are widely used vehicles for messenger RNA (mRNA)-based therapeutics and vaccines. However, ionizable lipids used in LNPs can be susceptible to N-oxide impurities that can cause functional loss of the mRNA cargo.
Metabolite identification and peace of mind
Managing metabolite identification (Met ID) studies is challenging, so what is at the top of your priority list as you plan the year ahead? Ensuring you have the data needed to manage product safety, meeting deadlines, staff recruitment and training, maintaining compliance, capital expenses, or something else?
The costly consequences of unplanned downtime
Unplanned downtime is a formidable adversary that businesses across various industries strive to minimize. Defined as the unexpected interruption of regular operations, unplanned downtime can wreak havoc on productivity, profitability and customer satisfaction. In this article, we delve into the causes of unplanned downtime, its far-reaching consequences and strategies to mitigate its impact.
Beyond mRNA: how advances in analytical techniques are enabling a revolution in the RNA drug landscape
Currently, there are 3 main types of in vitro transcribed (IVT) RNA drugs. Two of these—conventional messenger RNA (mRNA) and base-modified mRNA (bmRNA), which incorporates chemically modified nucleotides—are non-replicating. The third type is self-replicating RNA (srRNA), which is based on an engineered viral genome but devoid of viral structural protein genes. Its self-replicating ability makes srRNA a promising tool for new therapeutic drugs.
Changing the game of drug development with the Intabio ZT system
What better to learn how a new technology like icIEF-UV/MS is advancing drug development than hearing from the labs that are using it?
The whys behind the dos and don’ts of oligonucleotide analysis
We know that LC-MS oligonucleotide analysis can have its share of challenges—challenges with sensitivity, challenges with adduct formation and challenges with data analysis, to name just a few. That’s why this blog takes a closer look at the dos and don’ts of this type of analysis and explores some keys to success. It also explains why following these simple rules can vastly improve your oligonucleotide characterization and quantitation efficiency and success.
Overcoming N-nitrosamine analysis challenges with mass spectrometry and chromatography solutions
N-nitrosamine analysis has raised significant concerns in the pharmaceutical industry since 2018, when these potential carcinogens were found in several angiotensin II receptor blockers (sartans). Subsequent discoveries in ranitidine and some slow-release metformin medications prompted widespread product recalls. The industry has implemented stricter manufacturing requirements and intensified efforts to evaluate and control N-nitrosamine contamination. To meet stringent regulatory requirements, it is essential to develop effective chromatography and mass spectrometry (MS) methods for N-nitrosamine analysis. This blog addresses the challenges associated with detecting N-nitrosodimethylamine (NDMA) in metformin drug products.
