There i go, I am seting an equipment and I am using a shimadzu LC 20AD, but not for HPLC, I am using it to enter my reactive into the reactor. I mix it with the carrier gas through a "T" and after that they goes together. I am having a problem, I am seeing my reactive when the pump is not pumping, so I think it is working like a "vacuum tube" (I hope these are the correct words) and the gas is sucking in the liquid. I know that I could put a valve before the "T" to stop it but I have the doubt if the pump would not seal properly and I have to do some maitenance and change some broken joint.
Does anyone have some idea?
Thanks in advance for your response.
