Error -2,147,213,486

I am in the process of running multiple high sensitivity DNA chips back to back on our 2100 Bioanalyzer and after running two chips I began receiving the following error message on almost all of the samples in each chip. I ran the suggested daily cleaning protocol from the manual and still received the same error message on more than half of the samples on the next chip. The samples are recently made (<1 week old) whole-genome shotgun sequencing libraries that we are trying to check before sending for sequencing. The reagents we are using are from a brand new reagent kit and all of our pipets were calibrated less than 2 weeks ago. Our bioanalyzer was last serviced in 2012 but has been working fine until this. Any help is appreciated.

Error Message

-2,147,213,486

The lower marker could not be found automatically as there are no valid peaks in the detection area between 38s and 48.5s. If possible, you should try to lower the integrator height threshold or add a peak using manual integration to solve this problem.

-2,147,213,486

The upper marker could not be found automatically as there are no valid peaks in the detection area between 98s and 129s. If possible, you should try to lower the integrator height threshold or add a peak using manual integration to solve this problem.

  • Hello,

    Thank you for your post. These errors are due to the software not being able to call the Lower Marker (LM) and Upper Marker (UM) peaks correctly. There could be a number of root causes and without seeing your data, I do not want to speculate on what the root cause may be. Please share the raw data files in the .xad format with your local support team. Please visit Contact Us | Agilent to find the contact information of your local support team.  

    Best Regards,
