Concept explainers
Interpretation:
The positively charged fragments (or) ions that can be accelerated through the analyzer tube have to be identified from the given options.
Concept introduction:
Fundamental of Mass spectrometer: It is one of powerful tool in
Basic principle: It generates multiple ions from the sample under investigation, it than separates them according to their specific mass to charge ration (m/z) and records the relative abundance (RA) of each ion types.
Importance components of mass spectrometer:
Ion Source: The producing gaseous ions the substance being studied.
Analyzer: The resolving the ions into their characteristic mass components according to their mass charge ratio.
Detector system: This part detecting the ions and recording the relative abundance of each resolved ionic species.
