化学检验工技师考试九（Chemical examination Technician Examination nine） The ninth chapter lays down the standard This chapter mainly introduces the development trend of chemical examination at home and abroad, the basic knowledge of national standard and subject matter, and requires students to master the ability of enterprise standard and improve the comprehensive quality of students. Section 1 development trend of chemical inspection technology at home and abroad A combination or combination of analytical methods The separation and analysis methods of combination and combination, form a cascade, multidimensional technology is the rapid increase of flux and effective method to enhance the analysis function, are used in proteomics, and therefore become the focus of research direction. Two 、 highly sensitive detection and single molecule single cell analysis As the dimensionality increases, the separation of samples becomes finer and finer, and many difficult to separate components can thus be separated, which poses a new challenge to the detection. Three, miniaturization, integration and chip technology In order to increase the throughput and reduce the cost of analysis and sample consumption, the development of miniaturization, miniaturization, integration and analysis of new technologies has become an important trend. Four, functionalization For the analysis of complex systems, we can use exhaustive or partial exhaustive analysis methods, and also adopt sensor technology, probe method, affinity immunization and other highly selective methods. Five, a large number of preparation Analytical chemistry is not confined to analytical functions. Second national standards, line formulation 1. standardization Standardization means that in the social practices such as economy, technology, science and management, the consistency of repeated things and concepts is reached through the formulation, publication and implementation of standards, so as to obtain the best order and social bene
