The embodiment of the invention relates to testing or analyzing materials by means of determining chemical or physical properties of the materials, in particular to a system and a method for measuring the purity of CO 2. The system comprises a sample introduction pipeline for receiving CO < 2 > to be measured and at least one impurity component measuring assembly. Each impurity component measuring assembly comprises a switching piece and two impurity component measuring pieces used for measuring the impurity content. The measuring ranges of the two impurity component measuring pieces in the same group are different, and the switching piece is set to determine whether to switch to another impurity component measuring piece in the same group to be communicated with the fluid of the sample injection pipeline according to the measuring range of the impurity component measuring piece which is currently communicated with the fluid of the sample injection pipeline and the measured impurity content. According to the
