Analysing substances - AQA Flame tests and chemical tests are used to detect and identify ions in samples. Instrumental methods of analysis are faster, and more accurate and sensitive than simple ...

It can be used for relatively simple analyses, where the type of compound to be analyzed (‘analyte’) is known, to do a quantitative analysis to determine the concentration of the analytes.

quantitative analysis measures how much. Chemical analysis evaluates composition and pH; physical analysis measures gloss, strength, color. Organic analysis detects carbon-based traces of plants ...
