Analysis of Sugar Alcohols by Semi-micro HPLC

By Masao Bounashita

PDF IconDownload This Application

October 9, 2024

Introduction

Semi-micro HPLC analysis offers a significant advantage compared with conventional separations in reducing separation time and cutting cost by reducing the consumption of mobile phase. However, HPLC systems designed for conventional separations often do not provide good enough peak shape or separation due to peak diffusion in the non-optimized flow path. When using a semi-micro column an optimized RHPLC system is recommended. This analysis report compares the measurement of sugar alcohols using a conventional refractive index detector with a detector optimized for semi-micro HPLC.

Experimental

EquipmentConditions
Pump:PU-4185Column:Inertsil Amide (2.1 mmI.D. x 250 mmL, 3 μm)
Pump Option:Degasser unitEluent:Water/Acetonitrile (30/70)
Autosampler:AS-4150Flow rate:0.2 mL/min
Column Oven:CO-4060Column temp.:30ºC
Detector:RI-4035Injection volume:1 μL
  Standard Sample:Sugar alcohols mixture (5 mg/mL each)

Keywords

Sugar Alcohols, reverse phase HPLC, refractive index, Glycerine, Erythritol, Xylitol, Solbitol, Inositol

Results

Fig. 1 shows chromatograms of sugar alcohols measured using a refractive index detector for conventional analysis (RI-4030) or for semi-micro analysis (RI-4035). The RI-4035 for semi-micro analysis obviously provides much-improved peak shape and resolution.
