Switching from SEC column to RP column gives pressure error
Lately we've been doing both SEC and RP work. Since we have a 4 column Column Manager it is quite feasible to do both in a short period of time. In fact we are hoping to make use of SEC and RP in a 2D system we hope to purchase. The maximum pressure conditions for the SEC columns are usually 5000 to 6000 psi but, of course, the RP columns have a much higher max pressure. When we go from RP to SEC this does not present a problem but going from SEC to RP gives a pressure error and the system stops. Is there a way to overcome this? Our local system engineer told us to just start a new sample method with the RP column which does work but it means that we can't prime before starting the sample method. It seems to me that if we have selected the RP column in the Acquity console the system should realize that it can take a higher pressure.
