### Troubleshooting Tips for Optimal Use

1. Peak Shape Issues

Poor peak shape can arise from several factors, including column overloading, mobile phase composition, or incorrect flow rates. To troubleshoot these issues, laboratory personnel should ensure that the sample size is appropriate for the column's specific capacity and evaluate the mobile phase's composition. For instance, using a too-high concentration of salts or buffers can lead to tailing peaks and poor results.

2. Retention Time Variability

Inconsistent retention times can undermine data reliability. Such variability can stem from changes in sample matrix, temperature fluctuations, or variations in mobile phase composition. Regular calibration of the chromatography system, ensuring consistent temperature conditions, and preparing mobile phases meticulously can help mitigate these issues.

3. Low Sensitivity in Detected Compounds

When low sensitivity is an issue, factors like insufficient sample concentration or inappropriate detector settings could be the culprits. To enhance sensitivity, users should adjust detector parameters and increase the injection volume, keeping in mind the column's specifications to avoid overloading. Furthermore, optimizing the chromatographic method can significantly impact overall sensitivity.
