What branch of chemistry carries out tests to identify an unknown substance?
Analytical chemistry is concerned with investigation of the quantitative and/or qualitative characteristics of a given sample. For instance, an analytical chemist may qualitatively determine what the various polycyclic aromatic hydrocarbons in a tar sample are, and may also quantitatively analyze the concentrations of each species in the sample.
How do you know if a sample is more contaminated than other?
Methods of analytical chemistry are applicable.

Why the sample storage is one of the important steps in an analytical procedure?
Simply because it may be some time before the sample arrives back at the lab. Furthermore, if you collect it in a container that is not adequate, you may introduce contamination on sampling. Decomposition may be an issue also, if stored incorrectly.

Distinguish between a gross sample and a laboratory sample?
In geology say, a gross sample would be a representative sample of the whole rock. A lab sample would be a fraction of that, refined such that measurements are able to be made on a single mineral. for example, a piece of basalt would be a convenient field (gross) sample, from which say, mica is extracted after grinding and separation, to enable the 'date' of the basalt to be determined. Similar concepts would apply in other fields, such as biology, botany, water sampling and so on.
