3 Overview
Ion Chromatograph (hereinafter referred to as the instrument) is composed of infusion system, injection system, separation system, detection system and number
According to an analysis instrument composed of a processing system and the like, FIG. 1 is a block diagram showing the composition thereof. Ion chromatograph according to each sample
Separation is achieved by the difference in the distribution of the component ions between the stationary phase and the mobile phase in the column. Bring the sample into the chromatogram by the mobile phase
In the column, different ions are separated and separated with the mobile phase, detected by a detector and recorded by a data processing system.
Figure, qualitative and quantitative analysis based on retention time and response (peak area or peak height) of each component.
The key components and materials that affect the metering performance are shown in Table 1.
