What is the difference between modern instrumental analysis and chemical analysis methods?
Modern instrumental analysis, if only the instruments used to implement traditional chemical methods, they have the same principle, the determination of the object is no different;
The function of the instrument to replace some artificial action, five concept identification and human, to speed up the progress of the analysis, to reduce the number of human errors; but if the principle is the use of new technology to achieve detection, then the determination object may be different, the determination of some heavy metals such as traditional chemical methods, may require chemical titration reaction each other through a variety of substances to judge analysis, a large number of samples needed before processing can be realized, but modern spectral instruments can realize nondestructive testing, do not need to complete the reaction through the middle to qualitative or quantitative, also do not need to sample pretreatment.
