Write down the instrumental and chemical methods of analysis?
Instrumental approaches refers to the use of instruments to carry out different processes of analytical chemistry.
- The interaction between electromagnetic waves and atoms or molecules in a sample can be measured using spectroscopy.
- The method of mass spectroscopy is used to determine the ratio of a molecule mass to its charge by applying electric and magnetic fields.
- In electrochemical analysis the analyte is put in an Electrochemical cell, and the voltage or current flowing through it is determined using this method.
- Calorimetric studies are done to find the interaction between an analyte and energy in the form of heat.
Gravimetric analysis is a method of quantitative chemical analysis in which the constituent sought is converted into a substance (of known composition) that can be separated from the sample and weighed
Volumetric analysis can be defined as any method of quantitative chemical analysis in which the amount of a substance is determined by measuring the volume that it occupies or, in broader usage, the volume of a second substance that combines with the first in known proportions.
