Development of a stability-indicating method for esomeprazole and related degradation products by automated method scouting and mass detection

Instrument Type: LCMS

Demonstrate a streamlined method scouting workflow for the analysis of esomeprazole and related degradation products.

Complementary analysis in a biopharmaceutical research laboratory with a 2D-LC-MS instrument for flexible operation

Instrument Type: LCMS

The application note describes an efficient approach for identity confirmation of protein-based impurities of a therapeutic protein by multi heart-cut 2D-LC-MS in a top-down experiment. In addition the Thermo Scientific™ Simple Switch™ technology enables the instrument to be used in multi heart-cut 2D-LC-MS, 1D-LC-MS, or Dual 1D-LC mode for the most flexible equipment and lab space utilization and maximum MS productivity.

Increase sensitivity in UHPLC-MS analysis by minimizing post-column dispersion

Instrument Type: LCMS

Reduce post-column dispersion with small ID capillaries for fast gradient UHPLC-MS methods using sub-2 μm particle next-generation columns

Forced-degradation evaluation of erythromycin by HPLC and single quadrupole mass spectrometry

Instrument Type: LCMS

Simple stability-indicating LC-MS method for erythromycin. Compare the impurity profiles of an erythromycin reference standard with stressed analyte.

Impurity profiling of the synthetic peptide LL-37 using high-performance liquid chromatography with combined UV and single quadrupole mass spectrometric detection

Instrument Type: LCMS

Leveraging UV detection for the determination of the impurity levels and mass detection for identification of the active pharmaceutical ingredient (API) and other product related impurities using a rapid method for synthetic peptide impurity profiling
