PURPOSE: To enable analysis with high accuracy by installing an electrode plate having a sample passage hole in the position spaced from the top end of a capillary for introducing a liquid chemical material and impressing a voltage between the capillary which is an introducing means and the electrode plate.
CONSTITUTION: A capillary 1 in which the sample discharged from a high-speed liquid chromatography passes and an electrode 2 having a sample passage hole are provided and about 1,500W3,000V voltage is impressed between the tube 1 and the electrode 2. An inflow port 3 for hydrogen for the 1st flame, the 1st flame 5, the 2nd flame 6 and an inflow port 7 for hydrogen for the 2nd flame 6 are provided. The 2nd flame 6 is formed in mixing with the resulted product of combustion of the 1st flame 5. Flame light is detected via a filter 8 by a photocell 9. A hole 10 for passing cooling water or other liquid is provided. The device which is practically usable as a stable liquid chromatography having high accuracy is thus provided.
