【简介】
HPLC is a popular method of analysis because it is easy to learn and use and is not limited by the volatility or stability of the sample compound. The history section illustrates the HPLC's evolution from the 1970's to the 1990's. Modern HPLC has many applications including separation, identification, purification, and quantification of various compounds. It is important for those using HPLC to understand the theory of operation in order to receive the optimum analysis of their compounds. For those interested in purchasing or using an HPLC we have included a list of manufacturers, a troubleshooting guide, technical assistance, and a bibliography to help reduce your personal research and referencing time. Once you have completed the theory of operation, you will be qualified to take a quick quiz to test your understanding of HPLC systems.
