Grain and oil testing of cereals and their products sodium, magnesium, potassium, calcium, Chromium, manganese, iron, copper, zinc, arsenic, selenium, cadmium and lead Inductively coupled plasma mass spectrometry1 ScopeThis standard specifies the inductively coupled plasma mass spectrometry determination of cereals and their products sodium (Na), magnesium (Mg), potassium (K), calcium (Ca), chromium Principles of Reagents and Materials for Cr, Mn, Fe, Cu, Zn, As, Se, Cd and Pb ,instrument Equipment and equipment, analysis steps, results calculation and precision requirements. This standard applies to the determination of Na, Mg, K, Ca, Cr, Mn, Fe, Cu, Zn, As, Se, Cd and Pb in cereals and their products.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 6682 analytical laboratory water specifications and test methods3 principleThe sample digestion solution is atomized and introduced into the plasma (ICP) by a carrier gas, passed through a high-temperature ion source by evaporation, dissociation, atomization, ionization, etc. Cheng, into positively charged ions, the ion reaches the mass spectrometer (MS) through the lens system, the mass spectrometer separates according to the mass-to-charge ratio, the mass spectrometry signal The intensity (CPS) is proportional to the number of ions entering the mass spectrometer, ie the ion count of the mass spectrum is positive with the concentration of the analyte in the sample solution Ratio, by measuring the number of ions in the mass spectrometry to determine the content of the sample elements compared with the standard series --- "internal standard method of quantification" to calculate the sample In the test element content.4 Reagents and materialsUnless otherwise specified, the reagents used are excellent pure, the experimental water should be consistent with GB/T 6682 provisions of a water. 4.1 Nitric acid. φ (HNO3) = 65%, if necessary, re-distillation or use of high-purity reagents. 4.2 Hydrogen peroxide. φ (H2O2) = 30%. 4.3 Nitric acid solution (2 98). Measure 20 mL of nitric acid (4.1), slowly add 980 mL of water and mix well. 4.4 Mass spectrometry tuning solution. Buy a certified national standard solution directly; mixed mass spectrum tuning solution of lithium (Li), yttrium (Y), thallium (Tl), etc. The concentration is 10 μg/mL. Before use with nitric acid solution (4.3) diluted to a concentration of 0.010μg/mL. 4.5 Internal standard solution. directly purchase the certified national standard solution; scandium (Sc), germanium (Ge), indium (In), bismuth (Bi) Degree is 10 μg/mL. Before use with nitric acid solution (4.3) diluted to a concentration of 1.0μg/mL. 4.6 inorganic elements mixed standard stock solution. direct purchase of certified national standard solution; the concentration of sodium, magnesium, chromium, manganese, iron, copper, zinc, arsenic, Cadmium 50μg/mL, potassium, calcium, selenium, lead 100μg/mL. 4.7 Inorganic elements mixed standard solution. According to the need to learn appropriate amount of inorganic elements mixed standard stock solution (4.6), with nitric acid solution (4.3) The standard solution of sodium, magnesium, chromium, manganese, iron, copper, zinc, arsenic and cadmium was diluted to 5.0 μg/mL by level.
