Answer:It uses ion exclusion on a hydrogen-form sulfonated polymer phase for suitable organic acids.
Answer:The analytical column has 10 µm particles and dimensions of 7.9 mm inner diameter × 300 mm length.
Answer:The matching Shim-pack SCR(H) guard column is a separate accessory for protecting the analytical bed.
The Shimadzu Shim-pack SCR-101H column separates organic acids using ion-exclusion liquid chromatography. It contains a hydrogen-form sulfonated polystyrene stationary phase with 10 µm particles in a 7.9 mm internal-diameter by 300 mm column. The hydrogen ionic form distinguishes this column from the sodium, calcium and lead forms in the Shim-pack SCR-101 family, which have different separation mechanisms and selectivity. Ion-exclusion analysis can resolve mixtures of low-molecular-weight organic acids when an appropriate acidic aqueous eluent and detector are selected. Condition the resin with the intended mobile phase before sample injections, and maintain a consistent operating temperature for reproducible retention. Samples should be clarified and filtered when necessary to protect the column inlet from particulate contamination. Use a compatible dedicated guard column for additional protection during routine work. This item is the full analytical column, not a sugar-analysis column in another ionic form or a replacement guard cartridge.
