Dionex 1100 pump motor

Hi all,

This forum seems to focus on Hplc, so forgive me and redirect me if I am in the wrong place.

1100 is giving an error message of "pump motor control lost". When the pump is dismantled and inspected visually, a carbon residue is apparent. The pumps need replaced on an almost yearly basis.

Has anyone noticed this apparent flaw in pump design or is it possible we are doing something wrong. Our current resolution is to turn the IC off for any long periods of downtime to preserve pump life.

More info can be divulged if anyone has any thoughts or ideas.

Thank you,
Riverbrat

We built our IPD meta-analysis within a systematic review and sought to examine all the relevant evidence. Examination of comparative effectiveness is limited to randomized, controlled trial. In addition, in order to investigate the safety rhBMP-2, we asked all the observation and its use in spine surgery that reported side effects. Results of investigations reporting bias are presented in our full report, and have been submitted for publication elsewhere.
