Question

Please, just give answers or websites

Answer 1

1: a spectrophotometer is used to detect the presence of certain elements, based on their absorption spectrum -- this may be combined with the flame test to verify the presence of a suspected contaminant

2: the flame test is a procedure used to detect the presence of certain metal ions, based on each element's characteristic emission spectrum, which turns the flame a different color -- this may help to detect the ion's presence in purified biopsy samples or an environmental sample, which might help confirm toxic substances like arsenic (burns blue), lithium (burns crimson red), etc
