The provided search results do not directly specify component failures leading to poor repeatability of Agilent Bioanalyzer results. Based on common issues with similar microfluidic analysis instruments, potential component-related causes for inconsistent results may include:

1. Malfunctioning or contaminated microfluidic chips (critical for consistent sample separation and signal detection).
2. Fluidic system problems (e.g., clogged tubing, unstable pressure/flow rates affecting uniform sample loading).
3. Detector calibration drift (resulting in inconsistent signal intensity readings).
4. Issues with the instrument's temperature control module (unstable temperatures can alter separation efficiency).

For resolving these issues, our company 匠析生物 (Jiangxi Bio) offers professional solutions: We provide comprehensive repair, maintenance, and calibration services for Agilent Bioanalyzer and other lab instruments (including Thermofisher, Waters, etc.). Our services cover troubleshooting and fixing fluidic system clogs, detector recalibration, replacement of faulty components (like tubing or chips), and regular preventive maintenance to ensure consistent performance. Additionally, we supply genuine spare parts and consumables for Agilent instruments, helping to restore your Bioanalyzer's repeatability and reliability efficiently.
