TRACE DETECTOR AND ANALYTICAL METHOD FOR TRACE DETECTOR

摘要

A trace detection device comprises an analysis chamber that delimits an analysis area (21), wherein the analysis chamber has a case that has an inlet (22) for feeding a substance to be detected into the analysis chamber and an outlet (23) for discharging a sample-carrying gas from the analysis chamber. A control unit controls the trace detection device in such a manner as to keep a fluid communicating between the inlet and the analysis chamber and also between the outlet and the analysis chamber, allowing for continuous feeding and sampling during the pre-concentration state. An analysis method for the trace detecting device is also disclosed.
