Abstract
A sampling apparatus includes a pressure-reducing safety unit, which includes a device accommodation chamber that accommodates safety devices and a cylinder connection chamber, and a cylinder unit. The cylinder unit removably accommodates a cylinder, excluding an exposed portion where a front end portion of the cylinder, a mouthpiece, and a cylinder on-off valve are exposed, in an openable/closable casing. The exposed portion of the cylinder is formed so as to be insertable from the open surface portion of the cylinder connection chamber into the cylinder connection chamber, the mouthpiece of the cylinder and a hydrogen outlet of a supply pipe of the device accommodation chamber are connected by using a flexible hose, and thereby a sample of hydrogen gas is taken into the cylinder.
