• Injection Valve Cleaning

This reduces the delay volume of the system by about 70 µl and allows
the gradient changes to reach the column sooner.
• Enable overlapped injection also switches the injection valve from mainpass
to bypass after the injection has taken place either after the sample has
flushed out of the injector or at some specified later time in the run. The
injector will then aspirate the next sample in readiness for the next
injection thus reducing the overall cycle time and increasing the sample
throughput.
• Injector Cleaning allows the injection system to be flushed with solvent.
• Injection Valve Cleaning allows the valve to be switched at setpoints during
the run to minimize carryover when problem compounds are injected.
