HPLC Solvents: Definition, Types, Characteristics, Selection and 3+ FAQs
HPLC solvents are liquid compounds used as part of the mobile phase to carry analytes through the column. High-Performance Liquid Chromatography (HPLC) is one of the most widely used analytical techniques in pharmaceutical development. It is used for separating, identifying, and quantifying compounds in a mixture. Solvents play a crucial role in this process, as […]
Isocratic vs Gradient Elution In HPLC: How to Choose In 9 Minutes
Isocratic elution and Gradient elution are two fundamental modes of mobile phase composition control in HPLC. In HPLC, isocratic elution maintains a constant mobile phase composition throughout the separation, while gradient elution involves progressively changing the mobile phase composition during the run. Gradient elution is typically preferred for complex mixtures with components that have a […]
Role of pKa in Reverse Phase HPLC Method Development: Learn In 3 Minutes
pKa in Reverse Phase HPLC governs peak elution. It plays a unique and critical role in the separation of analytes as it directly influences selectivity
What Is Role of pH In HPLC Separation: Learn Easily In 7 Minutes
pH plays a crucial role in the retention and separation of ionizable compounds in HPLC. By adjusting the mobile phase’s pH, analysts can control the ionisation state of analytes—whether acidic or basic—which directly influences their interaction with the stationary phase and ultimately their elution time. This allows precise control over the separation of compounds with […]
Process Validation vs. Product Validation in Pharmaceuticals: Get Mastery In 3 minutes
Process validation and product validation are distinct yet complementary activities essential to ensuring quality in pharmaceutical manufacturing. Process validation confirms that the manufacturing process consistently yields products meeting predefined specifications, while product validation verifies that the final product meets its intended use and quality requirements. In pharmaceutical development, both the drug and its manufacturing process […]
