Gas phase ion-molecule reactions are one of the important synthetic pathways for Tholin formation in Titan's Atmosphere. We have developed a new instrument to observe the low temperature ion molecule reaction. We construct the low-temperature drift cell to investigate the associative charge transfer (ACT) reactions. In order to confirm the property of the low-temperature drift tube, associative reaction N_2^++ N_2+He-> N_4^++ He was measured. It is conclusively pointed out that the rate coefficient was guaranteed in a low temperature range.
