sample syringe overpressure 1161psi

Dear All,

Our Waters e2695-2998 system has been turned off on Monday night, and when I turn on the separation module on Wednesday morning, there is an error message saying that: 'sample syringe overpressure 1161psi' on the screen.

This is the first time I saw this error message. I carried on dry/wet prime, prime needle wash, prime seal wash as usual, but so far I haven't tried any injection yet.

Can anyone explain why this happen? I always make sure I filter the sample before injection...

your help will be much appreciated!

Anyone work on the injector recently?

What's in your needle wash solution?

What's in your mobile phase(s)?
Thanks,
DR
