for referenced documents without a date, the latest version (including all amendments) applies to This document: GB/T 4842 Argon GB/T 6379:1 Accuracy (trueness and precision) of measurement methods and results Part 1: General principles and definitions GB/T 6682 Specifications and test methods for water used in analytical laboratories GB/T 13966 Terminology of analytical instruments GB/T 16631 General rules for high performance liquid chromatography GB/T 27411 Uncertainty assessment methods and expressions commonly used in testing laboratories GB/T 27417 Guidelines for Confirmation and Validation of Chemical Analysis Methods for Conformity Assessment JJG1151 Liquid Chromatography-Atomic Fluorescence Spectrometer JY/T 0566 General rules for atomic fluorescence spectrometry analysis3 Terms and definitionsGB/T 6379:1, GB/T 13966, GB/T 16631, GB/T 27411, GB/T 27417 and JY/T 0566 and the following The following terms and definitions apply to this document: 3:1 Chemical forms A specific form of a chemical element, defined by its isotopic composition, electronic or oxidation state, and/or complex or molecular structure: 3:2 Speciation analysis Analytical work that identifies and/or quantitatively measures one or more chemical forms of a specific element in a sample:4 Principle of analytical methodThe components containing specific elements in the sample are separated after entering the chromatographic column with the mobile phase, and the specific elements are then generated into gaseous state in a certain way: The material is reduced to ground state atoms in the atomizer; the ground state atoms of the specific elements in each component are excited by the specific wavelength radiation of the light source After that, the emitted fluorescence time-resolved signal (i:e:, chromatogram) is used for qualitative and quantitative analysis of the morphology of the component to be tested: The retention time of each chromatographic peak of the test component of the quality substance/standard sample is compared for qualitative analysis: ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 43968-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 43968-2024_English as soon as possible, and keep you informed of the progress.
