It covers chemical kinetic methods using reaction rates, radiochemical methods using radioactive decay, and flow injection methods where samples react and move with carrier streams. Chemical methods are useful for slow reactions and enzyme analysis; radiochemical methods utilize isotopes, and flow injection is ideal for fast sample processing.

Despite the diversity of chemical kinetic methods, by 1960 they no longer were in common use. By the 1980s, improvements in instrumentation and data analysis methods compensated for these limitations, ensuring the further development of chemical kinetic methods of analysis.
