Another ionization mode would be Atmospheric Pressure chemical Ionization (APcI). APcI allows for high flow rates typical of HPLC to be used directly, often without diverting the larger fraction of volume to waste. Typically these mobile phase / analyte sytems are heated to temperatures in excess of 400 degrees Celsius, sprayed with high flow rates of nitrogen and the entire aerosol cloud is subjected to a corona discharge that creates ions. The term "chemical" ionization comes from the fact that the initial ions produced are typically those of the mobile phase and it's modifiers. The analyte is ionized by charge transfer during collisions in the high (atmospheric) pressure region of the outer source. —Preceding unsigned comment added by 165.121.88.56 (talk) 04:35, 30 April 2003
HPLC?[edit]
Is HPLC "High Pressure Liquid Chromatography"?—Preceding unsigned comment added by 68.6.232.198 (talk) 21:59, 27 September 2003
- Yes indeed. I fact if one says that the "P" in the acronimus HPLC stands for performance, he provides the technic of an attribute,which cannot be demonstred. —Preceding unsigned comment added by 212.239.13.34 (talk) 15:58, 25 November 2004
