Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using.

CLASSICAL METHODS OF ANALYSIS OF MATCHED DATA As a technique for the control of confounding, stratification may be introduced either at the design stage of a study or during the analysis of results. An advantage of using it in design, keeping a constant ratio of controls to cases in each stratum, is that one avoids the ...

chemical analysis - chemical analysis - Classical methods: The majority of the classical analytical methods rely on chemical reactions to perform an analysis. In contrast, instrumental methods typically depend on the measurement of a physical property of the analyte. Classical qualitative analysis is performed by adding one or a series of chemical reagents to the analyte.

The advantages of instrumental methods over classical methods include: 1. The ability to perform trace analysis, as we have mentioned. 2. Generally, large numbers of samples may be analyzed very quickly. 3. Many instrumental methods can be automated. 4. Most instrumental methods are multi-channel techniques (we will discuss these shortly). 5.
