Comparison of Analysis of Organic Acids with 4 Kinds of Detectors (Standards)

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.


Sample :
1. Citric acid
2. Tartaric acid
3. Malic acid
4. Succinic acid
5. Lactic acid
6. Formic acid
7. Acetic acid
8. Levulinic acid
9. Pyroglutamic acid

Columns      : Shodex RSpak KC-G (6.0mmID*50mm) + KC-811 (8.0mmID*300mm) x 2
Eluent       : 3mM HClO4 aq.
Flow rate    : 1.0mL/min
Column temp. : 50deg-C
