Описание (английский):

This document specifies the test method for the determination of hexachlorobenzene (HCB) in pyrotechnic compositions by gas chromatography. The limit of detection depends on the substance to be determined, the equipment used, the quality of chemicals used for the extraction of the sample, and the clean-up of the extract. Under the conditions specified in this document, a limit of detection of 1 mg/kg (expressed as dry matter) can be achieved.

Abstract

Overview

ISO 22863-2:2020 defines a laboratory test method for the determination of hexachlorobenzene (HCB) in pyrotechnic compositions using gas chromatography. The procedure covers sample preparation, extraction, purification and GC analysis with a flame ionization detector (FID). Under the specified conditions a limit of detection (LOD) of 1 mg/kg (dry matter) can be achieved.

This part references ISO 22863-1:2020 for general sample preparation requirements and complements it with HCB‑specific procedures and acceptance criteria.

Key Topics

Analyte: Hexachlorobenzene (HCB), CAS 118-74-1 (purity 99.5% when used as standard).
Sample size and prep: Typical sample mass is 1 g; extraction is a solid–liquid procedure using chromatographic-grade solvents (n-hexane or preferably ethanol or heptane).
Extraction steps: Mix sample with solvent, vortex 2 min, centrifuge at 3 000 r/min, repeat extraction twice, combine extracts and evaporate to
