牵涉到习题：

Mass spectrometer(光谱学仪)

Edexcel笔试局概要明确要求：

be able to predict mass spectra, including relative peak heights, for diatomic

molecules, including chlorine, given the isotopic abundances

CAIE笔试局概要明确要求(9701)：

a) analyse mass spectra in terms of isotopic abundances

(knowledge of the working of the mass spectrometer is not required)

b) calculate the relative atomic mass of an element given the relative

abundances of its isotopes, or its mass spectrum

AQA笔试局概要明确要求：

The principles of a simple time of flight (TOF) mass spectrometer, limited to ionisation, acceleration to give all ions constant kinetic energy, ion drift, ion detection, data analysis.

The mass spectrometer gives accurate information about relative isotopic mass and also about the relative abundance of isotopes.

Mass spectrometry can be used to identify elements.

Mass spectrometry can be used to determine relative molecular mass.
