Sample Management

Sample Rheodyne Injectors

How the injector is coordinated with other HPLC modules??
❑ The mobile phase is delivered to the sample

injector through which a sample solution is

introduced into the column.
❑ The injector functions as a stream diverter, Load

allowing the loading of a sample into the

injector loop without loss of system

pressure.
❑ Once the sample is loaded, the mobile

phase flow is diverted back through the 113
loop to the column.
