Statistics and Analytical Chemistry

Vocabulary flashcards related to the key concepts in the course of Statistics and Analytical Chemistry.

Analytical Chemistry

A scientific discipline that develops methods and strategies to obtain information on the composition and nature of matter.

Quantitative Analysis

Provides information about the amount of each substance in a sample.

Qualitative Analysis

Provides information about the elements and compounds in a sample.

Gravimetric Methods

Methods that measure the mass of the analyte or a compound chemically related to it.

Volumetric Methods

Methods that measure the volume of a solution containing sufficient reagent to react completely with the analyte.

High-Performance Liquid Chromatography (HPLC)

A technique in analytical chemistry used to separate, identify, and quantify components in a mixture.

Atomic Absorption Spectroscopy (AAS)

An analytical technique used for detecting metal elements in samples by measuring the absorption of light.

Gas Chromatography (GC)

A method for separating and analyzing compounds that can be vaporized without decomposition.

Good Laboratory Practice (GLP)

A system of quality assurance for research and testing involving chemical products.

Good Manufacturing Practice (GMP)

A system that ensures products are produced consistently and controlled according to quality standards.

Retention Time (tR)

The time it takes for a particular solute to pass through a chromatography column.

Distribution Constant (Kc)

The ratio of the concentration of a solute in the stationary phase to that in the mobile phase at equilibrium.

Selectivity Factor (α)

Describes the separation of analytes on the column and the difference in retention between components.

Peak Symmetry

Refers to the shape of chromatographic peaks; can indicate the efficiency of the separation.

Resolution Factor (Rs)

A measure of the efficiency of a chromatography column and the separation of two components.
