SUBSAMPLING DEVICE AND METHOD
A subsampling device (100) includes a flange member (110) in which a through hole (114) to be in communication with a housing space (11) of a sample storing container (10) is formed, and which is formed with at least one first piping path (112) to be in communication with the through hole (114), and which is coupled to a rear end face of the sample storing container (10), a coupling member (120) in which a cavity to be in communication with the through hole (114) of the flange (110) is formed, and which has a first end coupled to the through hole (114) of the flange member (110), a cylindrical casing which has a front end connected to a second end of the coupling member (120), includes a ball valve (134) disposed at a nearby location to the front end, and formed with at least one second piping path (132) formed at a nearby location to a rear end of the cylindrical casing and in communication with an internal space (135) thereof, a sampling pipe (140) which is provided with a bulk head (142) that divides the internal space (135) into a front space (136) and a rear space (138), includes a collecting blade formed at a front end, and slides in the internal space (135) of the cylindrical casing (130), and a sample container which can be replaced with the flange member (110), and which is connected to the first end of the coupling member (120). The sliding sampling pipe (140) causes the collecting blade to contact a sample (20) in the sample storing container (10) to perform subsampling on the sample (20) so as to be held at the front end of the sampling pipe, and the sample (20) having undergone the subsampling is stored in the attached sample container replaced with the flange member (110).
