Column Overload in Gas Chromatography with Vacuum Ultraviolet Detection
Column overload is a very commonly encountered issue in GC for beginners. Changes in peak symmetry, generally observed as peak fronting, can be subtle in the sharp peaks generated by GC, but the result can be significant shifts in retention times, loss of resolution, and error in peak integration.
Micro-SPE Desalting With Reduced Losses
New! Micro-volume TARGA® C18 SPE chemistries to desalt peptide, glycopeptide or glycan samples. Desalting with the water wettable, TARGA® C18 UltraMicroSpin™ columns, by loading in 100% water, improves recovery of these polar molecules prior to LCMS. Try our TARGA C18 as your desalting protocol, today! The Nest Group, Inc. - “Not Just Columns ... Answers!” Learn More

Comprehensive Multilevel Characterization of Biologics Using Sheathless Capillary Electrophoresis Hyphenated to Tandem Mass Spectrometry
An analytical methodology for the characterization of the primary structure of biotherapeutic proteins using sheathless CE–ESI-MS-MS instrumentation is presented. For the first time, complete sequence coverage can be achieved using a bottom-up proteomic approach from a single analysis of a tryptic digest. In a biosimilarity assessment, a single amino acid substitution was detected.
