A differentially pumped rare gas absorption cell has been developed to suppress high order harmonic radiation on the atomic and molecule physics beamline at National Synchrotron Radiation Laboratory. The gas filter system contained a gas absorption cell and two differential pumping systems considering the present status of atomic and molecule physics beamline. The adjustment results indicated that the pressure of Ar in the gas cell should be lower than 1.333×103 Pa while preserving the beamline vacuum to <4.933×10-7 Pa. When the pressure of Ar in the gas absorption cell was set to 1.241×103 Pa
the filter factor of gas filter system was better than 99.975%. Generally speaking
the adjustment results of the gas filter system were in agreement with the design parameters and could meet the experimental requirement very well.
