Chromium-gold coated fused silica emitters for electrospray ionization have been fabricated with lifetimes upwards of 100 hours. The coating on these emitters is extremely durable withstanding electrical discharges, abrasion and mechanical stress. Usable flow rates range from 30 nL/min to 1 mL/min u

Capillary electrophoresis CE and mass spectrometry MS were investigated for the analysis of paraquat and diquat herbicides. The mass spectrometer Ε½ . was a home-built time-of-flight instrument TOFMS equipped with an electro-Ε½ . spray ionization ESI source. A coaxial liquid sheath ESI source was util
We have established a method for separation and characterization of a series of peptide hormones of pharmaceutical interest and wide therapeutical use by capillary electrophoresis-electrospray-mass spectrometry (CE-ES-MS) using a sheath flow interface. Several parameters were systematically investig
