WebThis application note presents a CE-MS analysis of oligos by a ZipChip coupled to a QExactive HF mass spectrometer. This positive ESI mode method utilizes a MS-friendly background electrolyte (BGE), that … WebSep 14, 2016 · We develop a sheathless CE-MS interface with a sub-micron fracture directly in the capillary for electrical contact. • The simple design facilitates a stable ESI spray, a low (attomol) detection limit and well-resolved CE separation. • We apply the CE-MS setup for analysis of complex samples including mixtures of peptides and proteins. •

Evaluation of a new low sheath–flow interface for CE‐MS

WebThe Agilent capillary electrospray source allows users to interface capillary separation techniques with mass spectrometry. Ideal for limited sample quantities, the interface for … WebThis study was focused on examining the influence of gas flow parameters on capillary electrophoresis/mass spectrometry (CE /MS) performance using sheath-liquid CE /MS interfaces. The effects of nebulizing and drying gas velocity and drying gas temperature on CE separation and MS detection sensitivity were systematically determined. half smoke restaurant dc
