Title: Hydrogen flame ionization detector
Inventor: UEDA MASAHITO
IPC: G01N27/62
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To make adjustment so that a sample area value is increased as much as possible by equipping a position adjustment mechanism for adjusting the position relationship between a nozzle and a collector in a flame ionization detector body. SOLUTION: First, a collector housing 21 is rotated, and a screw is clamped so that a collector 8 touches a nozzle cap 5. Then, the collector housing 21 is rotated slightly in an opposite direction so that the distance between the collector 8 and the nozzle cap 5 becomes a specific value. Since the pitch of a screw 21a is constant, the distance between the collector 8 and the nozzle cap 5 can be determined by measuring the amount of rotation of the collector housing 21. The amount of rotation can be easily measured by observing a marker 23. Further, since the distance between the collector and the nozzle cap can be continuously changed by the screw 21a, an area value can be maximized by monitoring a detection signal and at the same time adjusting distance.
