With SUGAR
SH1011 and
SH1821, which operate under ion exclusion
and GFC modes, the use of perchloric acid aqueous solution allows analysis of
saccharides and organic acids in a single run. By changing the concentration (pH)
of the perchloric acid aqueous solution and the column temperature, the elution
time of organic acids can be adjusted. However, when using columns such as SH1011
and SH1821 whose counter ions are of H+ type for the analysis of sucrose in a
sample, measurement should be performed at a temperature as low as around 15 deg-C
for preventing the decomposition of sucrose.
