Frequently Asked Questions (FAQs)

What is the rule of three in HPLC?

The "rule of three" refers to the observation that retention time (k) changes approximately threefold for every 10% change in the organic modifier concentration (%B) in the mobile phase. For example, increasing acetonitrile from 40% to 50% may reduce retention by a factor of three. This principle aids rapid method development and optimization.

What is HPLC used for?

HPLC (High-Performance Liquid Chromatography) separates, identifies, and quantifies components in liquid mixtures. Common applications include:

• Pharmaceutical purity and potency testing
• Residual solvent analysis
• Food and beverage contaminant screening
• Environmental pollutant detection
• Pharmacokinetic and metabolite studies

It operates by pumping a sample mixture through a column packed with stationary phase under high pressure, separating compounds based on chemical affinity.

How to verify HPLC service provider reliability?

Validate reliability through:

1. Third-party audit reports of their quality management system (e.g., ISO 17025).
