How to Achieve Higher Injection Volumes
One way to achieve larger injections is to use a trapping column selected by a
switching valve to capture and concentrate the injection before switching it,
i.e. injecting it, onto an analytical column, see Figure 21 on page 52. The valve
can be conveniently located in the Thermostatted Column Compartment.
