Preparative techniques are scientific techniques. There are three main categories of preparative techniques. These include synthesis techniques, growth techniques, as well as purification techniques.
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
Bandwagon technique.
In the world of chess, Zaitsev is generally considered to have superior technique compared to Hofmann.
Tenebrism is a technique involving the intense use of chiaroscuro, where strong contrast between light and dark creates dramatic and dynamic effects in a painting. This technique was notably employed by artists like Caravaggio in the 17th century.
The technique commonly used to find the relative atomic mass (Ar) of an element is mass spectrometry. This technique involves ionizing the sample, separating the ions based on their mass-to-charge ratio, and then detecting and quantifying the abundance of different isotopes to calculate the average atomic mass.
This technique may be used to investigate the purity of,or to detect,particular antigens in sera ,culture filtrates,tissue or cell extracts,or fractions from any preparative procedure.-shweta
techniques to be used when preparing samples for in the lab
It can be done by several ways, like extraction decoction , preparative chromatographic separation, etc
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.
A benign pap smear with severe inflammation is usually caused by an infection or atrophic vaginitis. Reparative changes are changes that are caused by the inflammation present.

it is a crafting technique

There is no such thing as the Lincoln technique
Drumming is a technique. A drummer is a person, employing technique. (At least we hope so.)
Loaded Words is the technique that is used.
noun1) an object made by a human being, typically one of cultural or historical interest: gold and silver artifacts2) something observed in a scientific investigation or experiment that is not naturally present but occurs as a result of the preparative or investigative procedure:ex: the curvature of the surface is an artifact of the wide-angle view
