1.A false positive.The classic example of this is the contamination of almost any sample with sodium ions which gives an intense yellow line even when the sodium is only present as an impurity. 2. A false negative. Here again sodium ion is often
the culprit that masks other emissions unless the emissions are resolved
spectroscopically rather than simply visually. The eye is easily misled by
overlapping emissions.
