Eluents:

The pure water used as the mobile phase must be deionized water that has been passed through a 0.45 μm membrane filter. Before use, it must also be degassed to prevent generating bubbles in the column and at its outlet, because all columns of this series are heated being used. Use of degassing device is recommended.

SH type
Although deionized water can be used alone as the mobile phase, adsorption of alkalis on the packing will change the chromatogram. Addition of sulfuric or phosphoric acid to the mobile phase is, therefore, recommended to prevent that change. max 0.05 M H2SO4 / H3PO4 / HClO4

Sugars are slow in dispersing. A higher degree of resolution can, therefore, be obtained by heating the column to as high a temperature as the mobile phase permits. In normal operation, however, the standard conditions of use in Table above should be observed.

The columns of the SH type are not suited for high-temperature separation of sucrose and raffinose because their packing acts as a decomposing catalyst on those sugars. In case, however, use of the SH type for separation of such sugars is unavoidable, the column temperature should be lowered to about 40 °C to prevent their decomposition.

For simultaneous analysis of saccharides and organic acids

Standard columns | Base Material: Styrene divinylbenzene copolymer
