Data Name: Troubleshooting of Liquid Chromatography andMaintenance of automatic sampler

Most liquid chromatography systems use automatic injectors to introduce samples, and the correct use of automatic injectors is a basic condition for ensuring the separation accuracy of liquid chromatography systems. Injecting an appropriate volume of standard sample into an automatic sampler can provide a standard deviation of less than for the measurement of peak height and peak area. This article introduces the working principle of the automatic sampler and discusses the common problems encountered in use and their solutions.
