GB 31604.49-2016 National Food Safety Standard -Food Contact Materials and Articles – Determination of Arsenic, Cadmium, Chromium and Lead; Migration of Arsenic, Cadmium, Chromium, Nickel, Lead, Antimony and Zinc (English Version)
National Food Safety Standard -Food Contact Materials and Articles – Determination of Arsenic, Cadmium, Chromium and Lead; Migration of Arsenic, Cadmium, Chromium, Nickel, Lead, Antimony and Zinc
1 Scope
This standard specifies the inductively coupled plasma mass spectrometry and inductively coupled plasma emission spectrometry for the determination of arsenic, cadmium, chromium, nickel, lead, antimony and zinc migration after the food contact materials and articles are soaked in food simulants and specifies the inductively coupled plasma mass spectrometry for the determination of arsenic, cadmium, chromium and lead elements in paper products and corks.
This standard is applicable to the determination of arsenic, cadmium, chromium, nickel, lead, antimony and zinc migration in various food contact materials and articles and the determination of arsenic, cadmium, chromium and lead in paper products and corks.
Part I Determination of Arsenic, Cadmium, Chromium and Lead
Inductively Coupled Plasma Mass Spectrometry
2 Principle
After chipping, digest the paper products and corks with nitric acid, dilute the obtained solution with water and scale the volume, determine with the inductively coupled plasma mass spectrometer and compare with standard series for quantification.
3 Reagents and Materials
Unless otherwise specified, guaranteed reagents and Class-I water (defined in GB/T 6682) are adopted for the purposes of this method.
3.1 Reagents
3.1.1 Nitric acid (HNO3).
3.1.2 Argon (Ar): with purity ≥99.99%, or liquid argon.
3.1.3 Helium (He), with purity ≥99.995%.
3.2 Preparation of reagents
Nitric acid solution (5+95): measure 50mL nitric acid, slowly add into 950mL water and mix uniformly.
3.3 Standard product
3.3.1 Element standard stock solution (1000mg/L or 100mg/L): simple-element or multiple-element standard stock solutions approved and awarded with reference material certificate by the State are adopted for arsenic, cadmium, chromium and lead.
3.3.2 Internal standard element stock solution (1000mg/L or 100mg/L): simple-element or multiple-element standard stock solutions approved and awarded with reference material certificate by the State are adopted for scandium, germanium, indium, rhodium, rhenium, bismuth, etc.
