3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Ion Chromatography ionchromatography By ion exchange separation of ionic components, and then use the appropriate detector, it is a branch of high-performance liquid chromatography. 3.2 Guard column guardcolumn Before separation column placed to protect the separation column against particulate matter or irreversible contamination of impurities such reservations. 3.3 Separation column separatorcolumn According to the detected ion retention characteristics, it will be detected prior to detection of the ion exchange column separation. 3.4 Analytical column analyticalcolumuns After the guard column is connected in one or more separation columns for separating the composition of a series of test ion analysis system. All the pillars of the system The total capacity of the column analytical column with the contribution. 3.5 Suppressor suppressordevice Installed between the analytical column and a detector for detecting the response lotion reduce leaching of ionic components, in response to detection of an increase of the detected ion, A special device thus improving the signal to noise ratio. 3.6 Eluent eluant Phase flow of ions, the sample carrier through the analytical column. 3.7 Resolution resolution Under certain test conditions, a separate column continuous component analysis capability.
