HPLC stands for High Performance Liquid Chromatography, a technique used to separate, identify, and quantify components in a mixture.

• HPLC involves a stationary phase, a mobile phase, and a detector.

• The sample is injected into the system and carried by the mobile phase through the stationary phase.

• Different components in the sample interact differently with the stationary phase, leading to separation.

• The detector measur...read more

Dissolution stages refer to the different phases in which a solid substance dissolves in a liquid medium.

• Dissolution begins with the solid substance breaking down into smaller particles

• The smaller particles then disperse in the liquid medium

• Finally, the particles fully dissolve and become uniformly distributed in the liquid

UV and visible range refer to the wavelengths of electromagnetic radiation that are visible to the human eye.

• UV range typically refers to wavelengths between 10-400 nm, while visible range refers to wavelengths between 400-700 nm.

• UV radiation is divided into UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm).

• Visible light is the portion of the electromagnetic spectrum that is visible to the human eye and includes...read more

Normality, Molarity, and Molality are different units of concentration used in chemistry.

• Normality is the number of equivalents of a substance dissolved in a liter of solution.

• Molarity is the number of moles of solute per liter of solution.

• Molality is the number of moles of solute per kilogram of solvent.

• Normality is used in acid-base reactions, while Molarity and Molality are more commonly used in general chemistry.

• Ex...read more

OOS stands for Out of Specification and OOT stands for Out of Trend.

• OOS refers to a result that falls outside the acceptance criteria specified in the test procedure.

• OOT refers to a result that shows a trend outside the expected range over time.

• Both OOS and OOT results may indicate potential issues with the quality or consistency of the product being tested.
