Biodiesel Iodine Number Measurements via Capillary Zone Electrophoresis

A new method reduces iodine number determination for biodiesel to under 15 minutes total analysis time. The procedure uses capillary zone electrophoresis to quantify iodide ions after reaction with Wijs solution, requiring only microliter amounts of sample and reagents. Accuracy was verified against the standard method EN 14111.

Use Cases

• Calibrating rapid iodine number determination models based on the described CZE method.
• Comparing the precision of single-point versus multi-point calibration techniques for biodiesel analysis.
• Benchmarking new analytical methods against reported limits of quantification and determination values.

Strengths

• Total analysis time is reported as less than 15 minutes.
• Limits of quantification and determination are specified as better than 0.6 and 0.18 g per 100 g of biodiesel.
• Instrumental, intraday, and interday precisions are reported as better than 1.13%, 1.04%, and 6.02% RSD.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect methodological bias inherent to paperswithcode.
