Application Notes: LC-MS

Testing shows that Restek Long-Life ESI electrodes for Sciex Turbo V sources provide equivalent chromatographic performance to original equipment manufacturer electrodes over significantly longer lifetimes.

FDA recently posted an LC–HRMS method using the novel ACE3 C18-AR column, which can be used by regulators to detect “probable human carcinogen” NDMA in ranitidine.

An SFC-MS/MS method for high-sensitivity analysis of 34 PAs in commercial tea samples was developed.

• Analyzing biogenic amines in food by adding ion-paring agents • Case studies on polar aminoglycosides; paraquat/diquat; and BAs in food

Automated metabolic stability assays with sample incubation and LC-MS/MS determination are presented for use in drug metabolism and pharmacokinetic (DMPK) laboratories.

Fully automated extraction, removal of matrix interferences (phospholipids), and accurate determination of antibiotic compounds in eggs by LC-MS/MS is demonstrated.

Strata-X PRO was chosen to extract a panel of acids, neutrals, and bases from plasma. This simple method eliminates time-consuming method development and recovery for extremely polar analytes.

Strata-X PRO consists of a new type of polymeric SPE sorbent combined with matrix removal technology to revolutionize sample extractions and matrix clean-up by eliminates the conditioning and equilibration steps.

This application displays that for a range of pain relievers, an easy 3-Step SPE method can be implemented and produce high recoveries.

When working with milk as a matrix, Strata-X PRO SPE removes phospholipids more efficiently than traditional SPE to reduce any ion suppression that may occur during LC-MS/MS analysis.

In this webinar, learn how to achieve cleaner, more concentrated, and targeted sample preparation methods to help with downstream analysis for both analytical and biopharmaceutical labs.

For this peptide application, two different types of polymeric SPE (WCX and SAX) were tested in parallel with Strata-X PRO SPE and compared in regards to recovery and % variation.
