LC–MS

Using an Analytical Quality by Design approach, scientists recently identified impurities in a pharmaceutical product for hypertension treatment.

Using liquid chromatography-tandem mass spectrometry, scientists have found a similarity between the protective functions of the oral permeability barrier and the skin barrier.

While pesticides may be beneficial, they may also cause health risks in foods. In a recent study, scientists created new methods for detecting maximum pesticide residue levels.

Dipeptide profiles have an important role in detecting disease, and a recent study has made it much more accessible to study them.

By performing tissue analysis of caracals in captivity and in their natural African habitats, scientists were able to quantify uptake of toxic chemicals from the environment depending on how polluted they are.

A recent study was conducted using liquid chromatography–tandem mass spectrometry (LC–MS/MS) to identify the effect of cooking and storage on poly)phenolic compounds in piquillo peppers.

Join us to learn about novel, automated, and integrated software to support the analysis of the CQAs of oligos using LC–HRAM MS. Purity and sequencing data will be presented for a multitude of oligos including antisense, aptamer, and long synthetic samples.

Airing 1: Thursday November 10, 2022 at 9am EST Airing 2: Thursday November 10, 2022 at 2pm EST Polymer characterization is key to understanding their properties and ensuring the quality of final products containing polymers. Discover why light scattering and viscometry in size-exclusion chromatography become the new gold standard in polymer analysis.

Pepsin digestion and guanidine hydrochloride post-digestion can improve sequence coverage in antibody peptide mapping compared with trypsin digestion.

A critical step in any troubleshooting exercise—but one that I think is underappreciated—is recognizing that there is a problem to be solved.

Are generic workflows really needed in environmental analysis? In the end, it is the analyst— not instrumentation or software—that is in charge of what data are obtained, after thoughtfully considering what sample preparation and acquisition method to use.
