Instrument Technique for Chemical Analysis

Instrumental analysis is a branch of analytical chemistry that uses scientific tools to investigate analytes. Chemical analysis instrumental methods are classified into categories based on the property of the analyte to be measured. Many of the techniques are applicable to both qualitative and quantitative research. Instrumental methods are divided into three categories: spectral, electroanalytical, and separatory. The goals of instrumental chemical analysis are the same as those of qualitative and quantitative chemical analysis; the difference is that instrumental techniques, such as optical, electrochemistry, and chromatography, are utilized instead of qualitative and quantitative chemical analysis. This method can be used to perform a wide range of qualitative and quantitative analyses rapidly and accurately. Instrumental chemical analysis is based on the use of devices that are powered by electricity, and as a result, it is a relatively "new" part of Analytical Chemistry.
