Possibilities and new methodical decisions of determination of the analysis of total phosphorus and nitrogen in the plant raw material by means of capillary electrophoresis and atomic emission are considered. The existing methodical approaches to the preparation of plant samples to analysis are discussed
The maintenance of colloid substances, pepetide, polysugar, fibers and other characteristic substances of biological objects usually complicates the analytical definition micro- and macroelements, phosphorus, nitrogen. It is established that there are obvious problems during of curse of long preparation of biological tests for the analysis at the expense of summation of errors at a stage of samples preparation. The operating methods for samples preparation of biological raw materials for analytical research are discussed. The new methodical decisions for preparation of plant samples for determination of alkaline kations, earth alkaline metals and some heavy metals are offered. The possibilities and the conditions of application of various modes of microwave processing for extraction of mobile and general forms of kations and anions are considered. The various conditions of carrying out of oxidizing preparation of staples of vegetative raw materials for the subsequent definition of the general phosphorus and nitrogen are approved. The ways of biological samples preparation for definition of volatile components by a method of a gas chromatography and mass spectrometry are shown. The optimal conditions for samples preparation for definition of components with high temperatures of boiling are revealed. The main attention is paid to increase of accuracy and objectivity of measurements at the expense of improvement of methods of preparation of sample of a biological origin and observance of conditions of ecological safety at carrying out of analytical works.
The possibilities and new methodic decisions of determination of general nitrogen in the plant material by means of capillary electrophoresis and classic chemical analysis are considered. The operating systematic approaches providing control samples preparing are discussed.
