Gel permeation chromatography (GPC) is a type of size exclusion chromatography (SEC), that separates analytes on the basis of size.

Gas chromatography is used for analysis of other effluents, such as organic compounds.

Preparative methods to purify large amounts of protein, require the extraction of the protein from the electrophoretic gel.

Gel permeation chromatography is used to determine the number average molecular weight, weight average molecular weight, and polydispersity.

The first purified preparation of yeast CCP dates to Takashi Yonetani and his preparation by ion exchange chromatography in the early 1960s.

Chemical compounds exist in nature as mixtures, so the combination of liquid chromatography and mass spectrometry (LC MS) is often used to separate the individual chemicals.

The State party observes that as far as the admissible part of the complaint with regard to the Paadarskaidi area is concerned, the National Forest and Park Service mainly carried out increment felling (preparative cutting), in the area, amounting to approximately 110 hectares in 1998.

4.3 The State party notes that as far as the Paadarskaidi area is concerned, the National Forest  Park Service carried out increment felling (preparative cutting) totalling some 200 300 hectares between 1998 and 2000. The distance between the Angeli area and the Paadarskaidi area is about 30 kilometres.
