GOST R 55845-2013 PDF

Full title and description

ГОСТ Р 55845-2013 — «Реактивы и особо чистые вещества. Определение примесей химических элементов атомно-эмиссионной спектрометрией с индуктивно связанной плазмой». English title: Reagents and high purity substances. Determination of impurities of chemical elements by atomic-emission spectrometry with inductively coupled plasma. The standard specifies an ICP‑AES (ICP‑OES) analytical procedure for quantifying trace and minor elemental impurities in reagents and high‑purity substances used in analytical and production laboratories.

Abstract

This national standard defines the method, instrumentation, calibration, sample preparation, measurement conditions and quality assurance procedures for atomic‑emission spectrometry with an inductively coupled plasma (ICP‑AES/ICP‑OES) to determine mass fractions of a broad list of elemental impurities in chemical reagents and specially pure substances. It covers instrument performance requirements, preferred analytical wavelengths, procedures to prepare calibration solutions and internal standards, blank and control experiments, reporting formats and estimation of measurement uncertainty applicable to quality control and conformity assessment of high‑purity materials.

Scope

Applies to reagents and high‑purity substances and establishes the ICP‑AES method for determination of mass fractions of specific impurities including, but not limited to: Ag, Al, As, Au, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hg, In, Ir, K, La, Li, P, Mg, Mn, Mo, Na, Ni, Pb, Pd, Pt, Rh, S, Sb, Se, Si, Sn, Sr, Ta, Ti, Tl, V, Zn, Zr. The standard defines sample collection and preparation rules, instrumental and operational parameters, calibration and verification procedures, and requirements for result expression and uncertainty estimation.

Key topics and requirements

• Principle of method: excitation of analyte atoms in an argon ICP and measurement of emission line intensities related to element concentration via calibration functions.
• List of analytes: specified set of metals, metalloids and non‑metals commonly required for reagent/high‑purity verification.
• Instrumentation and performance: recommended wavelength range (approx. 160–850 nm), spectral resolution, detectors, argon flow control and recommended instrument types (axial and radial viewing options).
• Sample preparation: dissolution, acid cleaning and ultra‑clean reagents, use of purified acids and water, digestion and evaporation procedures where applicable, and use of high‑purity containers.
• Calibration and standards: preparation of intermediate and calibration solutions, multi‑element certified solutions, internal standards and calibration curve construction.
• Quality control: blanks, check standards, spiked recoveries, replicate measurements, instrument drift correction and performance verification.
• Metrological requirements: expression of results as mass fractions, limits of detection/quantification guidance, estimation of measurement uncertainty and conformity with laboratory competence requirements (reference to ISO/IEC 17025).
• Reporting: recommended report content, units, significant figures and statements of uncertainty.

Typical use and users

Used by analytical and quality control laboratories in chemical and pharmaceutical industries, manufacturers of reagents and high‑purity substances, research institutes, certification and metrology bodies, and laboratories performing incoming/outgoing product verification where trace impurity content must be controlled. Also used by laboratories seeking to demonstrate competence and traceability for ICP‑AES impurity testing.
