Abstract A new type of automatic sampling system for small biochemical analyzer was developed to fulfill the small but high-accurate requirements of automatic biochemical analyzing system. Small linear actuator was utilized to sample automatically. Then the system's structure was presented according to the equipment's performance requirements. Based on test data analysis system, error compensation curve was obtained and corrected. The final test results show that the system achieves the expected performance index and meets practical demands.
