  • sir thanks for valuable reply.
    This is not method related issue. Here i found that there is system limitation that when you will inject column condition or inject immediate standard on our Acquity H class and ARC system, the system was going in to idea condition at 30 min and the valve potion was changes. at same time flow was passing from  pump to column path not from flow through needle.
    So help me regarding this issue and make myself  whether i am right or wrong??
