Aliphatic alcohols were analyzed using SUGAR SH1011 and SH1821. Comparing the two chromatograms, the peak shapes with SH1011 are better than those with SH1821.


Sample :
1. Methyl alcohol
2. Ethyl alcohol
3. Isopropyl alcohol
4. n-Propyl alcohol
5. tert-Butyl alcohol
6. sec-Butyl alcohol
7. Isobutyl alcohol
8. n-Butyl alcohol
9. Isopentyl alcohol
10. n-Pentyl alcohol
