HYDROXAN™ COLUMNS

THE FIRST RUSSIAN-DEVELOPED PRODUCT OF ITS KIND

A Russian-made hydroxide-selective anion-exchange HPLC column designed for the qualitative and quantitative determination of trace concentrations of inorganic anions and low-molecular-weight organic acids in aqueous matrices.

COLUMN FEATURES

Production is located in St. Petersburg.

The matrix synthesis, particle functionalization, and packing of the sorbent into the column body are all developed in Russia. The microspheres are made of a highly cross-linked styrene-based polymer, providing mechanical resistance to pressures of up to 400 atm, compatibility with aqueous-organic media, and stability over a wide pH range.

The columns are compatible with both Russian-made chromatographs and instruments from international manufacturers, including Dionex. They perform effectively in both isocratic and gradient modes. Their high resolving power makes them suitable for a wide range of applied and research applications.

Enables the determination of low concentrations of target analytes in the presence of high concentrations of interfering anions.

Specialized applications include the selective determination of oxyhalides, particularly bromates, as well as haloacetates and other carboxylic acid derivatives.

Routine composition analysis of drinking water, groundwater, surface water, and treated wastewater for fluoride, chloride, nitrite, nitrate, sulfate, and other ions using either hydroxide or carbonate eluents.

Supports large injection loops without loss of accuracy when analyzing weakly detectable ions such as fluoride and carboxylates.

Compatible with hydroxide eluents, with detection limits down to hundreds of nanograms per liter.

Compatible with both Russian-made and imported instruments, including Dionex and others.
