A-level化学科目在A-level考试中是非常受欢迎的一门学科,但是很多第一次参加A-level考试的小伙伴,对于A-level化学课程了解的还不是很多,本文小编就为大家介绍一下化学考试中质谱仪及质谱的考点!
ALevel化学知识点详解
涉及到知识点:
Mass spectrometer(质谱仪)
Edexcel考试局大纲要求:
be able to predict mass spectra, including relative peak heights, for diatomic
molecules, including chlorine, given the isotopic abundances
CAIE考试局大纲要求(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考试局大纲要求:
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.
讲解内容:
Mass spectrometer的工作原理
包括Ionisation、acceleration、deflection等等
质谱(Mass spectrum)的相关计算
如何认知质谱(Mass spectrum)以及利用质朴计算相对原子质量Ar
适用于考试局:
AQA、Edexcel、CAIE等
