Mixer system for a liquid chromatography system
A mixer system for a liquid chromatography system has a mixer block, a plurality of fluid inlets which are connected to a mixing chamber by a respective channel, and a fluid outlet for mixed fluid. Each channel has a valve assigned thereto which is adapted to control the fluid flow. An adapter which is attached to the mixer block and through which one of the channels passes is provided for each valve. The valve is attached to the appropriate adapter, and the valves are arranged in an annular shape around the mixer block.
1. A mixer system for a liquid chromatography system, comprising:
a mixer block,
a plurality of fluid inlets which are connected to a mixing chamber by a respective channel, and
a fluid outlet for mixed fluid,
wherein each channel has a valve assigned thereto which is adapted to control the fluid flow,
wherein an adapter which is attached to the mixer block and through which one of the channels passes is provided for each valve, the valve being attached to the appropriate adapter, and the valves being arranged in an annular shape around the mixer block,
wherein each adapter includes a side wall on which the valve is arranged,
wherein a valve inlet section and a valve outlet section for the valve are formed in the adapter, and
wherein the valve inlet section and the valve outlet section open onto the same side wall of the adapter on which the valve is arranged.
2. The mixer system of claim 1 , wherein the fluid inlets are arranged on the mixer block.
3. The mixer system of claim 1 , wherein a fluid inlet is arranged on each adapter.
4. The mixer system of claim 1 , wherein the mixer block has a plurality of side faces and in that each adapter is attached to one of the side faces.
5. The mixer system of claim 4 , wherein the adapter extends obliquely to the corresponding side face.
6. The mixer system of claim 4 , wherein the adapter extends parallel to one of the side faces.
7. The mixer system of claim 1 , wherein the valve is oriented perpendicularly to the plane in which the adapter extends.
8. The mixer system of claim 1 , wherein each valve extends parallel to an adjacent adapter of an adjacent valve.
9. The mixer system of claim 1 , wherein the valve has the shape of a flat cuboid and the plane which the cuboid extends is oriented obliquely to the plane in which the adjacent adapter extends.
10. The mixer system of claim 1 , wherein each adapter is detachably fastened to the mixer block.
11. The mixer system of claim 1 , wherein each valve is detachably fastened to the corresponding adapter.
12. The mixer system of claim 1 , wherein at least one of the mixer block and the adapters are injection molded.
13. A mixer system for a liquid chromatography system, comprising:
a mixer block,
a plurality of fluid inlets which are connected to a mixing chamber by a respective channel, and
a fluid outlet for mixed fluid,
wherein each channel has a valve assigned thereto which is adapted to control the fluid flow,
wherein an adapter which is attached to the mixer block and through which one of the channels passes is provided for each valve, the valve being attached to the appropriate adapter, and the valves being arranged in an annular shape around the mixer block,
wherein the valves are not directly attached to the mixer block, but each valve is directly attached to an adapter which in turn is attached to the mixer block, and
wherein the valves have the shape of a flat cuboid.
