    • The invention relates to a method for measuring changes in the gas composition during reaction processes which occur in a reaction mixture. According to the method, the reaction mixture is introduced into a reactor and is brought into contact therein with a gas during an examination period. The change in the concentration of at least one relevant gas constituent which occurs during the examination period is measured. The invention provides that the examination period is split into separate time intervals, whereby in each of the time intervals, the reactor is filled with the gas, and the reactor is sealed in a gas-tight manner, or the gas is circulated in the reactor, the gas is emptied from the reactor, and the concentration of the gas constituent is measured. These steps are carried out in order to determine the change in the concentration. The system makes it possible to measure minute specific changes in the concentration of the corresponding gas constituent and to carry out measurements over long periods of time with high precision.
    • 本发明涉及一种用于测量在在反应混合物中发生的反应过程中的气体组成的变化的方法。 在该方法中,将反应混合物引入到反应器中,并在研究期内用气体带入反应器中接触。 检测到至少一个相关的气体组分的浓度在研究期间变化期间发生。 在该方法中,调查期间被细分成单独的时间间隔,其中,在每个时间间隔填充与所述反应器的气体和气密密封的反应器中,必要的,一个循环反应器中的气体,从反应器的气体的排空和测量浓度 的气体成分的发生,以确定在浓度的变化。 该系统允许在相关的气体成分的浓度低的比的变化,以及以非常高的精确度的长期测量的测量。
