1. Critical; requiring analysis.
2. Analytic.

Množina: analytical chemistries

Branch of chemistry that deals with the determination of the chemical composition of substances.
Qualitative analysis determines the elements or compounds in a given sample, without necessarily finding their concentrations, using methods such as chromatography and spectroscopy.
Quantitative analysis determines exact composition in terms of concentration, using such techniques as titration (volumetric analysis) and weighing (gravimetric analysis).

Množina: Analytical Engines

A mechanical calculating machine designed by British mathematician Charles Babbage in 1833 but never completed. It was the first general-purpose digital computer. See also Difference Engine.
Programmable computing device designed by British mathematician Charles Babbage 1833. It was based on the difference engine but was intended to automate the whole process of calculation. It introduced many of the concepts of the digital computer but, because of limitations in manufacturing processes, was never built.
Among the concepts introduced were input and output, an arithmetic unit, memory, sequential operation, and the ability to make decisions based on data. It would have required at least 50,000 moving parts. The design was largely forgotten until some of Babbage's writings were rediscovered 1937.
