PURPOSE:To obtain the liquid autosampler which can be simply moved by a small force and wherein manual injection is facilitated by sliding the part between two points on a circumference, with one point, which is fixed to the main body of the gaschromatograph, as an axis of rotation. CONSTITUTION:One ball caster 6 is attached to the liquid autosampler 4. The liquid autosampler 4 and a mounting table 3 can be rotated on a rotary shaft 5, a positioning plate 7 is fixed to the mounting table 3. The unitary body comprising these devices is aligned with a sample injecting hole 2 and fixed to the main body 1 of the gaschromatograph. In this constitution, when the liquid autosampler 4 is reciprocated between the two round holes in the positioning plate 7 which is mounted on the mounting table 3, with the rotary shaft 5 as a supporting point; the ball caster 6 is coupled into said round hole, positioning is performed, the liquid autosampler can be readily moved by the small force, and switching of the manual injection and the automatic injection can be readily performed. |
