Abstract 
 

 
The results of various methods in analytical chemistry are subject to different 

factors of countable number. Some of them may have insignificant, others significant 
impact on the results of analysis, which will orient the specialists to make true 
analysis to the extent of permissibility by holding their magnitudes at the optimal 
levels.
