Question

question # 8
multiple choice
quantitative analysis is carried out by a process called _.
o magnetic spectrometry
o mass spectrometry
o component spectrometry
o light spectrometry

Explanation:

Mass spectrometry is a technique used for quantitative analysis. It ionizes chemical species and sorts the ions based on their mass - to - charge ratio. Magnetic spectrometry is more about using magnetic fields for particle separation in a different context. Component spectrometry is not a standard term for this type of quantitative analysis. Light spectrometry (like UV - Vis, IR etc.) is more about qualitative and some semi - quantitative analysis based on light absorption/emission, but mass spectrometry is specifically well - known for quantitative analysis in many chemical and biological applications.

Answer:

mass spectrometry
