Chemistry - Which method?

Which method?

The method selected for a particular analysis may be influenced by a
variety of factors including required accuracy, available equipment and
stability of the sample being analysed.

Examples of the appropriate techniques for specific analyses include:

* heavy metals in water - AAS

* salt in potato chips - gravimetric analysis

* sugars and vitamin levels in foodstuffs - HPLC

* presence of calcium in an unknown salt - flame emission

* alcohol in wine - volumetric analysis or GC

* phosphorus in detergent - colorimetry
