When the needle port is flushed, the flushing solvent exits directly out this port without entering the sample loop. The needle port and syringe are never exposed to high pressure. The loop is self-cleaning, be- ing continuously flushed by mobile phase during analysis. VERSATILE INJECTION ...
The changing of solvents and the flushing of the pump heads take place by way of separate inlets and outlets in the throughflow via an active multiple-position high-pressure valve which can also close the pump head and can open it via the passive non-return valve. The regulating unit and ...
