What are the advantages of using instrumental methods over traditional chemical tests for identifying substances?

A high-scoring answer should explain compare instrumental methods with chemical tests in terms of speed, sensitivity and sample size. Use method first, observation second, conclusion last: name the relevant test or measurement, state the observation, and then connect the result to Instrumental methods.

This is correct because test observation is the evidence expected for chemical analysis, and supported conclusion is the result that supports the conclusion. A complete answer should use the approved objective wording, include the relevant evidence, and avoid unsupported identification claims.
