Ion Chromatograph Stayer

The basic ion chromatographic system Stayer is designed for the analysis of inorganic and organic ions in waters of various origins and in aqueous extracts, according to standardized and certified methods.

Used to determine inorganic F-, Cl-, NO3-, NO2-, Br-, SO42-, PO43-, Li+, Na+, NH4+, K+, Mg2+, Ca2+, Sr+ and other ions, as well as organic ions in aqueous solutions, natural, waste, drinking and bottled waters.

The Styer chromatograph includes a pump with a built-in degasser, a conductometric detector; thermostat and background conductivity suppression system available on request.

Key Features:

  • high sensitivity, reproducibility and analysis speed – from 15 to 20 minutes for basic anions;
  • the ability to work in one- and two-column versions;
  • polymer fluid path;
  • installation of any types of columns;
  • microprocessor control of system modules operation;
  • background conductivity suppression system;
  • high reliability and easy maintenance.

*- it is recommended to dilute samples with the concentration of these ions over 100 mg/l before analysis.

Accurate cell temperature control, combined with precision detector electronics and the use of high-performance columns, provide the necessary accuracy and reproducibility for the analysis of group 1 and 2 mineral cations, including the ammonium cation, at levels up to 200 ppb (µg/L) with direct sample injection in a single column mode.

The power supply of the ion chromatograph Stayer is carried out by single-phase alternating current with a voltage of 220V ±10% and a frequency of 50±1 Hz, power consumption is 150VA.

Currently, more than twenty methods have been developed for liquid chromatographs by Styer, including for ion chromatography:

  • a method for measuring the mass concentration of ammonium, potassium, sodium, magnesium, calcium and strontium cations in samples of drinking, mineral, table, medicinal table, natural and waste water by ion chromatography;
  • a method for measuring the mass concentration of fluoride, chloride, nitrate, phosphate and sulfate ions in samples of drinking, mineral, table, medicinal table, natural and waste water by ion chromatography;
  • method for measuring the mass concentration of chlorite and chlorate ions in drinking water by ion chromatography.

Additionally can be supplied:

1) chromatographic columns;

2) sample preparation equipment;

3) deionizer D-301.
