Say below and describe in detail according to ion gun capillary transferring regulating device of the present utility model with reference to accompanying drawing, wherein, Fig. 1 is the structural representation of the ion gun capillary transferring regulating device of the utility model specific embodiment.
As shown in Figure 1, the ion gun capillary transferring regulating device of the utility model specific embodiment comprises: atomization gas sleeve pipe 2, and atomization gas sleeve pipe 2 is hollow sleeve; Fixed sleeving 6, fixed sleeving 6 is hollow sleeve, and outer wall has screw thread, and atomization gas sleeve pipe 2 rear end is connected with fixed sleeving 6 front end, forms communication passage; Adjustable end cap 5, adjustable end cap 5 is arranged on fixed sleeving 6 rear end by screw thread; Kapillary installs adjusting sleeve pipe 4, and kapillary is installed adjusting sleeve pipe 4 and to be arranged in fixed sleeving 6 and to be connected with adjustable end cap 5; Kapillary 1, kapillary 1 and kapillary are installed adjusting sleeve pipe 4 and are fixedly connected, inner and stretch into atomization gas sleeve pipe 2 inside through fixed sleeving 6.
According to embodiments more of the present utility model, the utility model also comprises elastomeric element 3, and it is inner that elastomeric element 3 is positioned at fixed sleeving 6, and anterior and atomization gas sleeve pipe 2 is connected, and rear portion and kapillary are installed adjusting sleeve pipe 4 and be connected.
According to embodiments more of the present utility model, elastomeric element 3 is spring or polyurethane elastomer, and spring and polyurethane elastomer can play the effect that adjusting sleeve pipe installed by shoddy tubule.
According to embodiments more of the present utility model, the front end formation internal diameter of described atomization gas sleeve pipe is diminishing coniform.
According to embodiments more of the present utility model, adopt O-ring seal to be tightly connected between fixed sleeving 6 and atomization gas sleeve pipe 2, reduce production cost, facilitate daily servicing.
Principle of work of the present utility model is: kapillary 1 is fixedly mounted on kapillary and installs on adjusting sleeve pipe 4.Kapillary accesses syringe pump or other sample separation instruments (as liquid chromatography, Capillary Electrophoresis etc.) at the side inlet end near adjustable end cap 5, is the tested sample endpiece of preliminary cation near atomization gas sleeve pipe side.Atomization gas accesses in atomization gas sleeve pipe 2 from outside, and atomization gas, when atomization gas inside pipe casing, because the constant cross-section in atomization gas sleeve pipe is constant, can obtain comparatively stable gas flowing (comprising direction and speed two aspects); At atomization gas sleeve pipe front end place, rank street area reduces in shorter distance, and the flow velocity of gas and direction can change rapidly, and now gas can show the flow state being different from the former; In the exit of atomization gas sleeve pipe, do not have the restriction of atomization gas sleeve pipe, the pressure of gas can obtain unexpected release, and the linear velocity of gas can sharply increase, and forms the state of outwards spraying, and linear velocity is in the direction of the airflow in downward trend.Thus, when kapillary 1 is in different positions relative to atomization gas sleeve pipe, the flow velocity of atomization gas and direction are obviously that different, tentatively charged sample drops can obtain different atomization drying speed and effect.
