Hplc Program: ((exclusive))

mobile phase

High-Performance Liquid Chromatography (HPLC) is an analytical technique used to separate, identify, and quantify components in a chemical mixture. It relies on a liquid carrying a sample through a stationary phase (column) under high pressure to achieve high-resolution separation. Core Components of an HPLC System

1. 0 - 5 min, 95% A, 5% B
2. 5 - 20 min, Linear gradient to 40% A, 60% B
3. 20 - 25 min, 40% A, 60% B
4. 25 - 30 min, Linear gradient to 95% A, 5% B
5. 30 - 35 min, 95% A, 5% B

• Rationale: pH 3.0 ensures Ibuprofen (weak acid) is non-ionized but still retained.

The HPLC program must match the physical hardware. You cannot program a 0.5 mL/min flow rate for a standard 4.6 mm column if your pump only handles 1-10 mL/min. Key decisions: hplc program
