Comparison of CARB-413 Column and ODS Column (1)

The comparison of anaysis of N-methylcarbamates standards using RSpak CARB-413 column with isocratic elution and that using ODS column with gradient elution.
A good result was obtaioned using RSpak CARB-413 column. The time required for one anaylsis is almost same for both two cases. But, additional time is necessary required for reconditioning the system in the case of gradient elution though such additinal time is unnecessary in the case of isocratic elution. As the serult, total average time required for one analysis with isocratic elution is about half of that with gradient elution.
