our MS System (Agilent 5973) shows steady peaks of the calibrant PFTBA during all acquisitions. If the valve is switched off under manual tuning the ion peaks do not disappear and change in abundance. Also if the valve is getting purged there is no click sound. Did anybody experienced something like this? Could it be that the valve is steadily open and can't manage to close?
I would be very grateful for any advice!
