I
learned from the national industry standard information service
platform that three forensic science industry standards have been
officially implemented on 2022-05-01, involving the determination of
nitrite, hydrochloric acid, sulfuric acid and nitric acid by ion
chromatography. Some of the contents are excerpted as follows:
GA/T 1946-2021 Forensic Science - Examination of Hydrochloric Acid, Sulfuric Acid and Nitric Acid - Chemical and Ion Chromatography
Scope of application:
This document specifies chemical and ion chromatographic examination methods for hydrochloric acid, sulfuric acid, and nitric acid in the forensic sciences.
This document is suitable for the qualitative analysis of hydrochloric acid, sulfuric acid and nitric acid in the field of forensic science, and can also be used for reference in other fields.
principle:
Using
the principle of ion exchange, the chloride ion, sulfate ion and
nitrate ion in hydrochloric acid, sulfuric acid and nitric acid are
separated and qualitatively tested.
GA/T 1918-2021 Forensic Science-Nitrite Ion Testing Chemistry and Ion Chromatography
Scope of application:
This document specifies methods for the qualitative and quantitative analysis of nitrite ions in forensic science.
This document is suitable for the qualitative and quantitative analysis of nitrite ions in forensic in vitro samples and fresh samples such as vomitus, gastric lavage and gastric contents. Other test materials can be used for reference.
principle:
Taking the blank sample and the added sample as the control, according to the requirements of parallel operation, the test material was extracted and purified, and the chemical method and ion chromatography were used for characterization. Qualitative judgment basis; based on the ion chromatographic peak area, the external standard method was used for quantification.
GA/T 1916-2021 Forensic Science - Fluoroacetate ion detection in biological samples - Liquid chromatography-mass spectrometry
Scope of application:
This document is suitable for the qualitative and quantitative analysis
of fluoroacetate ions in forensic biological samples (blood, urine,
liver). Other test materials can be used for reference.
