Comparison of Analysis of Organic Acids with 4 Kinds of Detectors (Standards) (KC-811)

Print
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. 800ppm Citric acid
2. 900ppm Tartaric acid
3. 800ppm Malic acid
4. 700ppm Succinic acid
5. 1100ppm Lactic acid
6. 600ppm Formic acid
7. 700ppm Acetic acid
8. 1500ppm Levulinic acid
9. 1500ppm Pyroglutamic acid

Columns      : Shodex RSpak KC-G (6.0mmI.D. x 50mm) + KC-811 (8.0mmI.D. x 300mm) x 2
Eluent       : 3mM HClO4 aq.
