1 Scope

This document specifies a method for the determination of traces of perchlorate in mineral fertilizers by

ion chromatography and conductivity detection (IC-CD).
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

to fertilizers

3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 12944-1 and EN 12944-2

apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

4 Principle

The perchlorate content of the fertilizer sample is determined by ion chromatography with conductivity

detection after extraction in water. The ion chromatograph comprises a sample injection part, a

separation part and detection part. For lower noise and background level of detection, a suppressed

conductivity detector may be used. Anion exchange resin is used as stationary phase and aqueous

solutions of monobasic and dibasic salts are used as mobile phase.
5 Reagents

All reagents shall be of recognized analytical grade and shall have negligible concentration of the

element to be determined if compared to the lowest concentration of that element in the sample

solution.
5.1 Water, grade 1 according to EN ISO 3696.

5.2 Perchlorate standard solutions, with a mass concentration of ρ( ClO ) = 0,05 mg/l, 0,1 mg/l,

0,3 mg/l, 0,5 mg/l, 0,7 mg/l and 1 mg/l, prepared from a stock solution with verified concentration of

perchlorate, e.g. with ρ( ClO ) = 1 000 mg/l.
The 0,5 mg/l calibration standard is used for a regular calibration testing.

5.3 Quality control sample, with a mass concentration of ρ( ClO ) = 0,5 mg/l prepared from a

solution (e.g. ρ
