A system consists of several modules, the standard modules are:
4. Thermostat column
The pressure can be up to about 200 bar for normal HPLC.
By means of high pressure and proper contact with the stationary phase, a relatively high speed of separation and very good resolution is achieved. The run time can vary from 5 to 60 minutes for the measurement of one sample by HPLC.
An used HPLC system, is a system, which gest a 2nd change in the world. One laboratory in the west part of the world has a HPLC, which isn't used anymore. This system is bought by Labrecycling and sold to an another user, which is very glad with the older system.
