Effect of Column Temperature (RSpak KC-811)

Effect of column temperature on column efficiency when RSpak KC-811 is used for the analysis of organic acids is shown. Effect of temperature changes with kinds of organic acid. By changing the temperature of a column, the improvement of separation is possible.

Sample : Acetic acid

Column       : Shodex RSpak KC-811 (8.0mmID*300mm)
Eluent       : 0.1% H3PO4 aq.
Flow rate    : 1.0mL/min
Detector     : Shodex RI
Column temp. : 40deg-C
