Purification and analysis of the purity of NADH.
We developed an analytical reverse-phase high-performance liquid chromatographic procedure for rapid assessment of the purity of NADH. The method completely separates adenosine monophosphate and adenosine diphosphoribose from NADH. By use of this analytical technique we found that preparative chromatography on DEAE-cellulose gives NADH that is free from adenine nucleotides as well as other impu...
متن کاملClinical chemistry: a challenge for high-purity standards and reagents.
The dynamic interplay between preparation, handling, containment, and analysis of ultrapure chemical standards and reagents for the clinical chemistry laboratory is described. Inorganic as well as organic standards are reviewed. The contamination problems associated with water, acids, and solvents in trace-element analysis are defined and resolved. In addition, less well-known sources of error ...
متن کاملProtozoal Development and Natural Purification of Flowing Sewage
A large volume of literature has accumulated ?n the "self-purification" of sewage-contaminated streams and rivers, and the process of purification Under these conditions has been reported to be one to factors such as the turbulence and speed of flow of the polluted waters, the depth and type of the bed of the watercourse, the extent of dilutlQn, sedimentation, surface area, sunlight, temperatur...
متن کاملComparison of Material Flows in Sewage-free and Sewage-generating Flue-Gas Purification Systems of Municipal Waste Incineration Plants
During incineration of wastes in waste incineration plants, polluted flue gases are generated which have to be subjected to flue gas purification. Although the legal requirements are nearly unambiguous, the question of whether wet flue gas purification is to be performed in a sewage-free or sewage-generating manner is discussed controversially by experts in the Federal Republic of Germany. As a...
