I am using Agilent 1200 series GPC/SEC. Instrument shutdown after injecting the sample. Error message. Pressure above the set limit (200 bar). While the system is working totally fine before injecting the sample and there is literally no blockages in the system as the pressure is just 15 bar at 1 mL/min flow rate. I already have changes needle and seat capillary. Would be grateful if someone can guide me.
Many thanks
