84.Methods of analysis - detailed description of all operations required for the 
analysis of the object to the content of all or only of the component. 
84. Accuracy, reliability and accuracy of the analysis results - (systematic error 
analysis of the results tends to zero) and reproducibility, which shows the degree of

closeness to each other the results of individual measurements in the analysis of the 
sample material; 
85. Sensitivity - the applicability of the methodology to determine the lowest 
concentration component.
86. Selectivity (selectivity) methodology - a characteristic analysis method that 
determines the effect of interfering extraneous components of the sample; 
87. Express - characterizes the time of the analysis and results. 
88. Sample preparation - a set of actions on the object of analysis (grinding, 
homogenization, extraction, hydrolysis, precipitation, etc.) To convert the sample 
into a suitable subsequent analysis form (dry residue, solution and so forth.), The 
state of a substance (base, salt form, hydrolysis conjugates, etc.), as well as the 
concentration or dilution, removal of interfering components analysis. 
89. Chromatography - process based on multiple repetition of acts of sorption 
and desorption of substances while moving it in the mobile phase flow along the 
fixed sorbent. 
90. Paper chromatography - separation of substances is carried out on the 
special paper.
91. TLC - separation of substances is carried out in a thin layer of sorbent. 
92. Gas-liquid chromatography (GLC) - one of the most modern methods of 
multi-component analysis. (Stationary phase - the liquid applied to the solid 
support). The separation process is based on differences in volatility, solubility (or 
adsorption) shared components. 
93. High Performance Liquid Chromatography (HPLC) - high pressure liquid 
chromatography, high speed liquid chromatography, regardless of the separation 
mechanism in the HPLC mobile phase - liquid. 
94. Plates - for the sorbent substrate typically made of glass, aluminum foil or 
polyester film. 
95. Chromatography - method of separating mixtures of substances or particles 
based on differences in the speed of their movement in the system of immiscible and 
moving relative to each other phases. 
96. Column - includes chromatographic sorbent which performs the function 
separation into individual components of the mixture. 
97. Eluent - mobile phase (solvent or solvent mixture): gas, liquid, or (rarely) a 
supercritical fluid. 
98. The stationary phase - solid phase or fluid, connected to an inert carrier in 
adsorption chromatography - sorbent. 
99. Chromatogram - registering result depending on the concentration of the 
components of the output of the time column. 
100. Detector - a device for recording the concentration of components of the 
mixture at the outlet of the column. 
101. Chromatograph - the device for chromatography. 
102. Spots Rf -value value recovery is not dependent on the size of the plate, 
and time division (at a sufficiently small sample weight) of the component 
concentration in the sample and the presence of other components, that is a

comprising: providing, research and application of emission spectra, absorption and 
reflection in the ultraviolet region, ie. e. in the wavelength range of 10-400 nm.
