Abstract
An injector has a sample chamber for retaining a small amount of sample, wherein a position of the sample chamber is controlled by transmitting light through the sample chamber and detecting the transmitted light so as to recognize the position of the sample chamber, and it is possible to reduce detection error compared to the conventional injectors that indirectly control the position of the sample chamber by transmitting light through the light passage which is adjacent to the sample chamber. A method for injecting a sample comprising the steps of: providing an injector which has a sample chamber for retaining a sample with an open month; transmitting light through the sample chamber; detecting the transmitted light so as to recognize a position of the sample chamber; and controlling the position of the sample chamber by using the detection result to connect the open month of the sample chamber to an open month of a sample receiving member in order to inject the sample into the sample receiving member.
