    摘要: The present invention provides a method and apparatus for analyzing compounds with amino group(s) contained in biological organisms. In this method, a compound with amino group(s) is derivatized and then the derivative of the compound with amino group(s) is eluted by liquid chromatography using a stepwise elution means on a concentration gradient. Subsequently, the derivative of the compound with amino group(s) eluted from the liquid chromatography is detected by mass spectrometry.

    摘要: A vessel 1 comprises a container 2 for storing a sample solution containing a volatile substance and a stopper 3. The stopper 3 is formed with a through-pore 3a at the center, through which a vaporized volatile substance is discharged with exhaust gas. The stopper 2 is formed with a gas inlet port 3b and a gas outlet port 3c at the upper and lower edges, respectively, and a groove 3d connecting the both ports 3b and 3c at the side surface. On reducing pressure in the container 2, an external gas is blown into the container 2 from the gas outlet port 3c through the groove 3d at high speed and spirally rotates by centrifugal force along the inner wall of the container 2. This kicks up the sample solution to stir it, increasing the surface area of the solution and thus promoting vaporizing of the volatile substance.
