The pressure jumps as soon as the 6-port rheodyne valve in the autosampler switches into 'Load'. It isn't blocked (injection will still proceed without hitting max pressure at a lower flow rate), and back flushing through the valve doesn't lower the pressure any. I have also checked everything that comes after this valve, and there doesn't appear to be a problem with any of the fittings after the line leading into the column.
Any thoughts would be greatly appreciated.
Thanks.
