I am having difficulty with the Injector Tower on my Agilent 7890B not completing its cycle after an injection in on-column mode. The syringe sticks down in the inlet (megabore, 0.53mm column) and gives a fault. Any ideas or suggestions? Thanks.
I think I solved the problem! I changed the syringe needle guide when I didn't have to. I just remembered that the standard tapered needle 5 uL syringes can be used with megabore columns.
