Automatic sample injector with mobile needle to feed chromatographic capillary columns has been developed. Applied technical solutions make the sample deposition with micro syringes at the end the injector＇s needle easier and the inlet to the capillary column is protected from dropping of sample from the injector＇s needle. In the injector two independent gas lines has been applied - one to feed the capillary column and another for the sample evaporation from the injector needle. A PC class computer controls the injector operation.
