Chapter 10.1, Problem 1P

Interpretation Introduction

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 organic chemistry, used to quantity known materials, to identify unknown compounds within a sample and to elucidate the structure and chemical properties of different molecules.

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.

        $\begin{array}{l}\text{M}\stackrel{\begin{array}{l}electron\\ beam\end{array}}{\to }{\text{M}}^{\begin{array}{l}+\\ .\end{array}}+e^{-}\\ \text{[Molecule]}\text{molecular ion}electron\\ [\text{Radical}\text{cation}]\end{array}$

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.
