Abstract:
A device for the temperature-compensated determination of chemical parameters, comprising:an optical temperature sensor which contains a temperature indicator that has a temperature-dependent afterglow time and/or intensity of the luminescence and does not react with the surrounding medium, wherein said temperature indicator is present in a matrix which does not permit said temperature indicator to contact said surrounding medium;a chemical sensor which contains a chemical indicator that is sensitive to a chemical parameter;means for stimulating the temperature indicator and the chemical indicator to luminesce;means for measuring the luminescence of the temperature indicator and the chemical indicator; andmeans for establishing an optical connection between each of said respective indicators, said stimulation means and said measuring means;wherein said temperature indicator is different from said chemical indicator and both the temperature indicator and the chemical indicator are arranged within a optical sensor, wherein said chemical indicator is present in a matrix which permits said chemical indicator to contact said surrounding medium.
