Our 7600 couple with nanoLC Ultimate 3000 via contact closure. it has run without any loss connection during the batch. Just yesterday, the last injection keep equilibrating system until the LC finished the gradient run. We closed the software and power off LC and MS then started again but it did not help. The Dionex engineer also checked their LC and triggering cable found both are ok.

Anyboby has the similar issue as us and how do you solve it?

Best Regards,

Joy
