Final answer:
Spectroscopic analysis has the advantage of being non-destructive and allows for further testing, but it may require specialized equipment and be costly.
Step-by-step explanation:
One advantage of using spectroscopic analysis to quantify the amount of a chemical substance in a certain product is that it is non-destructive. This means that the sample being analyzed remains intact after the analysis is completed, allowing for further testing or analysis if needed. For example, in atomic spectroscopy, the sample can be reused for subsequent analyses.
One disadvantage of using spectroscopic analysis is that it may require specialized equipment or techniques. Spectroscopic analysis often involves the use of complex instruments, such as spectrophotometers or mass spectrometers, which may require expertise to operate and maintain. Additionally, the cost of acquiring and maintaining such equipment can be high.
