Analytical chromatography refers to the processes of separating a sample into its components and identifying these components, and is usually a small scale process. Preparative chromatography, on the other hand deals with isolating the separated components of a sample, and can be done on both small-scale or larger industrial scale operations. Preparative chromatography is a form of purification that utilizes chromatography.
there is no difference between high pressure and performance chromatography
GCMS involves running the sample through a mass spectrometer following the data received from chromatography. MS fragments the analytes to show patterns specific to the analyte (and the ionization technique and sector powers) therefore allowing the analyte to be identified. GC is used to separate all volatile substituents of a sample so they can be identified one by one.
Purum, Puriss, and Technical are the 3 purity grades in the new common Fluka and Riedel-de Haën classification system. The Puriss grade is >= 98.5% purity, Purum is >= 95.0% purity, and the Technical grade fluctuates, mostly >= 90% purity.

The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
Flash chromatography uses pressure (under 10 psi) to pump solvent down a column at a rate faster than gravity would provide. Vacuum chromatography uses a vacuum at the bottom of the column to pull solvent through. Both can be performed with standard glass columns, but usually vacuum chromatography is done with a silica filled vacuum funnel instead as a rough purification technique.

Analytical centrifugation is concerned mainly with the study of purified macromolecules(molar mass, shape etc) or isolated supra-molecular assemblies. This also allows to monitor the sample being spun through an optical detection system using ultraviolet light absorption and/or interference optical refractive index sensitive system.While preparative centrifugation methodology is devoted to the actual methodology of separation of cells, sub-cellular structures, membrane vesicles and other particles of biochemical interest

analytical thinking is of a set rules and process of thinking. Creative thinking is outside the box and no set pattern.

What are the differences between analytic and synthetic cubism?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
Analytical exposition focuses on presenting balanced arguments on a particular issue, while hortatory exposition aims to persuade and encourage the audience to take a specific action or have a certain attitude. Analytical expositions rely on facts and logical reasoning, while hortatory expositions are more emotionally charged and aim to motivate the audience to act or think in a certain way.
