Another approach is to get rid of the water in the hexane side and just use ammonium formate salt and formic acid in IPA … WebAbnormal peak shapes are a common problem when conducting routine analysis work. Peak abnormalities that are clearly noticeable in chromatograms include peak broadening (including extreme tailing or leading edges), shoulder peaks, and split peaks, as illustrated in Figure 1. If any of those peak abnormalities appear in chromatograms, they could ...
WebAnalysis by LC was carried out on a 25 cm x 4.6 mm Zorbax Rx-SIL (5 microns) with a mobile phase (1.4 ml min-1) of heptane-THF-acetic acid (96.5:3.5:0.015) and an in-line UV (365 nm) detector. The LC eluate was coupled through a Vestec universal interface to a Finnigan 4023 mass spectrometer. EI-mass spectra were obtained at 77 eV from m/z 200 ... WebDiscovery ® HPLC columns are efficient for the analysis of biomolecules and small molecules. These columns have polar and non-polar bondings, with unique retention, selectivity, and no-bleed properties for LC-MS applications. The Ascentis ® bonded phases have a wide range of selectivity. Type B silica makes the column inert, stable, and ...
