Two Options for Analyzing Potential Genotoxic Impurities in Active Pharmaceutical Ingredients

Two options for the analysis of PGIs in API have been developed by Merck and Restek to meet different laboratory needs. The first option is a fast method for the analysis of sulfonate esters on the Rxi-5Sil MS column. The second option is a comprehensive method for the analysis of both sulfonate esters and alkyl halides on the Rtx-200 column. Both methods require very little sample preparation, which helps increase laboratory productivity.

Excellent LC-MS Separation of Penicillins and Cephalosporins Using Ultra IBD Columns

Unlike C18 columns, Ultra IBD (intrinsically base deactivated) columns can interact in normal phase mode with analytes that possess charged functional groups, providing greater versatility for LC-MS analyses. Excellent peak shape in either normal phase mode or reversed phase mode increases sensitivity and improves quantification. The 4-page note shows example analyses of penicillins and cephalosporins.

Raptor Biphenyl LC Columns Brochure

Raptor LC columns combine the speed of superficially porous particles (i.e., SPP or “core-shell”) with the resolution of highly selective USLC technology. Featuring Restek's most popular LC stationary phase, the rugged Raptor Biphenyl is extremely useful for fast separations in bioanalytical testing applications like drug and metabolite analyses, especially those that require a mass spectrometer (MS).

Dissecting Raptor LC Columns: A closer look at a new species

When we engineered our superficially porous particle (SPP or "core-shell") Raptor LC columns, we developed the bonding chemistries that are best suited to both the SPP construction and our highly selective USLC phases. But we didn't stop here. Take a closer look at a new species as we dissect the upgraded hardware and new, proprietary packing techniques behind Raptor LC columns and Raptor EXP guard columns.
