# Guides for genetic analyzer users

Practical references for the people who run capillary electrophoresis instruments every day. Free to print and share in your lab.

## All guides

-

### [Compatibility chart](https://elis.al/guides/compatibility-chart/)

Arrays, polymers and buffers for each Applied Biosystems genetic analyzer, with OEM part numbers.

-

### [3500 troubleshooting guide](https://elis.al/guides/3500-troubleshooting/)

Likely causes and fixes for spikes, weak signal, broad peaks, pull-up, current errors and failed calibrations.

-

### [Maintenance checklist](https://elis.al/guides/maintenance-checklist/)

A printable schedule of daily, 14-day, monthly and yearly tasks for the 3500 and 3500xL.

## How to use these guides

Start with the compatibility chart when you order: it lists the capillary array, polymer and buffers for each instrument together with the OEM part numbers. When data or the instrument misbehaves, the troubleshooting guide sorts the most common problems by symptom and tells you what to check first. The maintenance checklist turns routine care into a printable schedule, so polymer, buffers, pump flushing and calibrations happen on time.
