ASTM D5788-95(2024) 将有机物加入水样中的标准指南

1.1  This guide covers the general technique of “spiking” aqueous samples with organic analytes or components. It is intended to be applicable to a broad range of organic materials in aqueous media. Although the specific details and handling procedures required for all types of compounds are not described, this general approach is given to serve as a guideline to the analyst in accurately preparing spiked samples for subsequent analysis or comparison. Guidance is also provided to aid the analyst in calculating recoveries and interpreting results. It is the responsibility of the analyst to determine whether the methods and materials cited here are compatible with the analytes of interest. 1.2  The procedures in this guide are focused on “matrix spike” preparation, analysis, results, and interpretation. The applicability of these procedures to the preparation of calibration standards, calibration check standards, laboratory control standards, reference materials, and other quality control materials by spiking is incidental. A sample (the matrix) is fortified (spiked) with the analyte of interest for a variety of analytical and quality control purposes. While the spiking of multiple sample test portions is discussed, the method of standard additions is not covered. 1.3  This guide is intended for use in conjunction with the individual analytical test method that provides procedures for analysis of the analyte or component of interest. The test method is used to determine an analyte or component's background level and, again after spiking, its now elevated level. Each test method typically provides procedures not only for samples, but also for calibration standards or analytical control solutions, or both. These procedures include preparation, handling, storage, preservation, and analysis techniques. These procedures are applicable by extension, using the analyst's judgement on a case-by-case basis, to spiking solutions, and are not reiterated in this guide. See also Practice E200 for preparation and storage information. 1.4  These procedures apply only to analytes that are soluble in water at the concentration of the spike plus any background material, or to analytes soluble in a solvent that is itself water-soluble. The system used in the later case must result in a homogeneous solution of analyte and sample. Meaningful recovery data cannot be obtained if an aqueous solution or homogeneous suspension of the analyte of interest in the sample cannot be attained. 1.5  Matrix spiking may be performed in the field or in the laboratory, depending on which part of the analytical process is to be tested. Field spiking tests the recovery of the overall process, including preservation and shipping of the sample. Laboratory spiking tests the laboratory process only. Spiking of sample extracts, concentrates, or dilutions will test only that portion of the process subsequent to the addition of the spike. 1.6  The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8  This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

GSO ISO/TR 19693:2024 表面化学分析 生物传感应用功能玻璃基板的表征

ISO/TR 19693:2018 gives examples of how methods of surface chemical analysis in the scope of ISO TC 201 are useful to characterize the nature of substrates used to produce biosensing devices. Successful characterization will give the opportunity for a better understanding of aspects of surface chemistries and reactions at each step of production influencing the overall performance of the final device, for example a microarray. The steps of preparation are the activation of the substrate by immobilization of linker molecules and the functionalization of the activated substrate with biomolecules required for specific biosensing, the so-called probes. Herein, a focus is set on silane-based functionalization of glass slides, a critical production step for subsequent immobilization of probe molecules. Those probes are used for sensing of biological recognition events. The silanization process has been selected because it is one of the most popular in biosensor production today. ISO/TR 19693:2018 gives an overview of methods, strategies and guidance to identify possible sources of problems related to substrates, device production steps (cleaning, activation and chemical modification) and shelf-life (storage conditions and ageing). It is particularly relevant for surface chemical analysts characterizing glass-based biosensors, as well as developers or quality managers in the biosensing device production community. Based on quantitative and qualitative surface chemical analysis, strategies for identifying the cause of poor performance during device manufacturing can be developed and implemented. This document shows how far the light may shine today and possible starting points for more specific activities of ISO/TC 201 in the future, which end in standardized procedures for measurements. No specific protocols on processing are discussed in this document. To learn more about protocols the reader is referred to specialized literature, see for example References [1] to [9].

ASTM E3063-24 中子活化分析法测定锑含量的标准试验方法

1.1 This test method covers the measurement of antimony concentration in plastics or other hydrocarbon or organic matrix by using neutron activation analysis (NAA). The sample is activated by irradiation with neutrons from a research reactor and the subsequently emitted gamma-rays are detected with a germanium semiconductor detector. The same system may be used to determine antimony concentrations ranging from 1 ng/g to 10 000 µg/g with the lower end of the range limited by numerous interferences and the upper limit established by the demonstrated practical application of NAA. 1.2 This test method may be used on either solid or liquid samples, provided that they can be made to conform in size and shape during irradiation and counting to a standard sample of known antimony content using very simple sample preparation. Several variants of this method have been described in the technical literature. A monograph is available which provides a comprehensive description of the principles of neutron activation analysis using reactor neutrons (1).2 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautions are given in Section 9. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
