Hope this helps a bit :)
Classical methods in instrumental analysis include gravimetric analysis, titration techniques, and colorimetric methods. These methods involve measuring the quantity or concentration of a substance based on its physical or chemical properties.
A wet chemical analysis procedure, such as a titration, may be chosen when the analyte can be easily characterized by a chemical reaction with a specific reagent. This method is often used when the analyte is present in high concentrations and when accuracy is more important than speed. Instrumental analysis procedures are usually favored when high sensitivity, precision, and speed are required, and when the analyte is present in trace amounts.
Advantages of flame emission include high sensitivity, wide dynamic range, and speed of analysis. However, disadvantages can include interferences from other elements, the need for sample preparation, and potential contamination of the flame.

To convert proximate analysis of coal to ultimate analysis, use the Dulong formula as follows: Carbon = 0.75*(fixed carbon + [volatile matter/100]); Hydrogen = 0.06volatile matter; Oxygen = [moisture/100] + 0.3sulfur - carbon - hydrogen; Nitrogen = volatile matter/100 * 0.01. This formula estimates the ultimate analysis (C, H, O, N) from the proximate analysis (moisture, volatile matter, fixed carbon, ash).
Disadvantages of titrimetryA. Capable of higher degree of precision and accuracy than instrumental methods of analysisB. Analysis can be automatedC. Cheap to perform and do not require specialized apparatusD. They are absolute methods and are not dependent on the calibration of the instrumentE. None

Disadvantages of video analysis include having to invest in PC hardware to do the analysis. The time that can be involved is another disadvantage.

There are several types of chemical analysis, including qualitative analysis, quantitative analysis, instrumental analysis, and spectroscopic analysis. These methods are used to determine the composition, structure, and properties of substances.
