New chelating resins immobilizing carboxymethylated polyallylamine (CM-PAA) were prepared by immobilizing PAAs with some molecular weights on methacrylate resins and then carboxymethylating a part of amino groups in the PAAs using various amounts of sodium monochloroacetate. The molecular weight of PAA barely affected both the amount of PAA immobilized on the resin and the relationship between the carboxymethylation (CM) rate and the ratio of the amount of monochloroacetate used in the CM step. The selectivity of CM-PAA resin for solid-phase extraction of trace elements was almost the same as that of a resin immobilizing carboxylymethylated polyethyleneimine; 10 elements, namely Cd, Co, Cu, Fe, Mo, Ni, Pb, Ti, V, and Zn, could be quantitatively recovered over a wide pH range and alkali and alkaline earth elements were scarcely extracted under acidic and neutral conditions. The CM-PAA resin was applicable to the separation and preconcentration of the elements in a certified reference material (Waste Water, EU-L-1) and a real environmental water sample (ground water).

High-performance liquid chromatography (HPLC) has great contribution in the analysis of the carbohydrates. Various separation modes such as ion exchange chromatography, size exclusion chromatography and partition chromatography have been applied to HPLC of mono- and oligosaccharides. Among them, partition chromatography with a polar stationary phase and aqueous mobile phase, called aqueous normal phase partition (ANP) chromatography, has been used in various fields, and is widely used for the separation of reducing sugars. Currently, this separation mode is considered to be a type of "hydrophilic interaction chromatography (HILIC)". As the use of HILIC mode increases, many novel stationary phases being available for the separation of reducing sugars have been developed. This article focuses on the separation of reducing sugars by ANP (HILIC) mode, and summarizes the traditional and/or recent stationary phases for the separation of reducing sugars. The applicability of various kinds of stationary phases to solid-phase extraction (SPE) of saccharides is also described.
