<p>PROBLEM TO BE SOLVED: To provide an element analyzer enhanced in the reproducibility of measuring accuracy by eliminating the scattering phenomenon of a liquid sample at the time of movement of a slider in a slide type sample injection part. SOLUTION: In a slide type TC sample injection part 51 equipped with a slider 51a, which slides between a TC combustion pipe 6 in which a sample 3 is injected and a drain pipe 5d for discharging the sample 3 for the purpose of washing, and an injection main body block 5b to which the TC combustion pipe 6 and the drain pipe 5d are fixed, a groove part 51b is provided on the bottom surface of the slider 51a so as to be positioned inside an O-ring 5f but outside a cavity 5g. By this constitution, during the movement of the sample injection pipe 5e positioned at the center of the cavity 5g from the drain pipe 5d to the TC combustion pipe 6, the gas in the TC combustion pipe 6 is discharged by the groove part 51b before the cavity 5g goes over the O-ring 5f to drop the pressure in the gas in the TC combustion pipe 6 and the scattering of the waterdrop of the sample bonded to the leading end of the sample injection pipe 5e is prevented.</p> |
