Agilent 1290 quaternary pump
Does anybody have experience of the reliability of the Agilent 1290 infinity Quaternary pumps (non-seal wash option). I am having regular pump failures (on multiple instruments) suggesting the seals will need replacing every couple of months. The systems are running reverse phase H2O/ACN with either 0.1%formic acid or TFA. ~20 samples/day running at pressures <600bar. My Waters Acquity systems never gave these problems (though they did have seal wash). Any suggestions of help would be appreciated.
