Comparison of Analysis of Organic Acids using RSpak KC-811 with 4 Kinds of Detectors was shown. When analyzing organic acid satndards, 4 kinds of detectors are usable. However,
when analyzing actual sample
, we recommend to use the post-column reaction method which allows high-selective analysis of organic acids.
