An exhaust gas analyzing system comprising: an introduction port for introducing exhaust gas; a main flow path with one end connected to the introduction port; a sampling pump (P1, P2) provided in the main flow path in order to sample exhaust gas sent from the introduction port; an analysis parts provided on the upstream side or downstream side of the sampling pump (P1, P2) in the main flow path in order to analyze exhaust gas; a main flow meters (FM1 - FM6) provided on the upstream side or downstream side of the analysis parts in the main flow path in order to confirm whether exhaust gas flows through the analysis parts with a flow rate required for analysis; and a pump abnormality determination part (8a, 8b) for determining abnormality of the sampling pump (P1, P2) by detecting whether or not a pump flow rate of the sampling pump (P1, P2) obtained by using output values of the main flow meters (FM1 - FM6) meets predetermined conditions of abnormal functioning, characterized in that the exhaust gas analyzing system further comprises an upstream-side opening/closing valve provided on the upstream side of the sampling pump (P1, P2) in the main flow path; a downstream-side opening/closing valve provided on the downstream side of the sampling pump (P1, P2) in the main flow path; an exhaust flow path (9, 10) connected between the sampling pump (P1, P2) and the downstream-side opening/closing valve in the main flow path; an exhaust flow meter (FM5, FM6) provided in the exhaust flow path (9, 10) in order to measure an exhaust flow rate in the exhaust flow path (9, 10); and a leakage abnormality determination part for checking leakage with the use of the exhaust flow rate while closing the upstream-side opening/closing valve and the downstream-side opening/closing valve and activating the sampling pump (P1, P2). an introduction port for introducing exhaust gas; a main flow path with one end connected to the introduction port; a sampling pump (P1, P2) provided in the main flow path in order to sample exhaust gas sent from the introduction port; an analysis parts provided on the upstream side or downstream side of the sampling pump (P1, P2) in the main flow path in order to analyze exhaust gas; a main flow meters (FM1 - FM6) provided on the upstream side or downstream side of the analysis parts in the main flow path in order to confirm whether exhaust gas flows through the analysis parts with a flow rate required for analysis; and a pump abnormality determination part (8a, 8b) for determining abnormality of the sampling pump (P1, P2) by detecting whether or not a pump flow rate of the sampling pump (P1, P2) obtained by using output values of the main flow meters (FM1 - FM6) meets predetermined conditions of abnormal functioning, characterized in that the exhaust gas analyzing system further comprises an upstream-side opening/closing valve provided on the upstream side of the sampling pump (P1, P2) in the main flow path; a downstream-side opening/closing valve provided on the downstream side of the sampling pump (P1, P2) in the main flow path; an exhaust flow path (9, 10) connected between the sampling pump (P1, P2) and the downstream-side opening/closing valve in the main flow path; an exhaust flow meter (FM5, FM6) provided in the exhaust flow path (9, 10) in order to measure an exhaust flow rate in the exhaust flow path (9, 10); and a leakage abnormality determination part for checking leakage with the use of the exhaust flow rate while closing the upstream-side opening/closing valve and the downstream-side opening/closing valve and activating the sampling pump (P1, P2).
