Abstract

An arrangement for mounting components in a heating chamber for heating a fluid of a fluid separation apparatus, wherein the arrangement comprises a mounting board having at least one mounting recess each configured for accommodating at least one component, and the at least one component each configured to be mountable in and/or on the at least one mounting recess.

First claim

The invention claimed is:

1. An arrangement for mounting components in a heating chamber for heating a fluid of a fluid separation apparatus, the arrangement comprising:
a mounting board comprising at least one mounting recess, the at least one mounting recess comprising slanted surfaces forming a V-shape; and
a pre-heater assembly configured for heating the fluid upstream and/or downstream of a separation unit of the fluid separation apparatus, the pre-heater assembly comprising slanted surfaces forming a V-shape, wherein the pre-heater assembly is configured to be mountable in the at least one mounting recess,
wherein the slanted surfaces of the pre-heater assembly are complementary to the slanted surfaces of the at least one mounting recess such that the pre-heater assembly and the at least one mounting recess have corresponding lateral surfaces substantially covering each other and faces of the lateral surfaces are pressed against each other.

2. The arrangement of claim 1 , wherein the pre-heater assembly comprises a capillary having a lumen configured for conducting the fluid and a thermal coupling body contacting at least part of the capillary and arrangable so that heat generated by a heat source is supplied to the capillary via at least part of the thermal coupling body.

3. The arrangement of claim 1 , further comprising a heat source configured for generating heat for heating the mounting board.

4. The arrangement of claim 3 , wherein the heat source is attached to the mounting board.

5. The arrangement of claim 3 , wherein the heat source is a Peltier heat source.

6. The arrangement of claim 4 , wherein the mounting board comprises a backside and a front side opposing the backside, the at least one mounting recess is arranged at the front side, and the heat source is attached to the backside.

7. The arrangement of claim 1 , comprising a feature selected from the group consisting of:
the mounting board is made of a material having a thermal conductivity of at least 150 W/(m K);
the mounting board is made of a material comprising aluminum or copper;
the mounting board is plate-shaped;
the at least one mounting recess is configured as at least one mounting groove within the mounting board; and
a combination of two or more of the foregoing.

8. The arrangement of claim 1 , wherein the at least one mounting recess comprises an interior recess section configured for accommodating the pre-heater assembly, and an exterior recess section arranged between the interior recess section and a surrounding outside of the mounting board and configured for accommodating an additional component.

9. The arrangement of claim 8 , wherein the exterior recess section comprises a feature selected from the group consisting of:
the exterior recess section comprises an undercut;
the exterior recess section comprises a triangular undercut; and
the exterior recess section comprises a T-shaped undercut.

10. The arrangement of claim 8 , wherein the exterior recess section comprises a dovetail-type undercut.

11. The arrangement of claim 8 , comprising a configuration selected from the group consisting of:
the interior recess section, the exterior recess section, the pre-heater assembly and the additional component are configured to match to one another so that the additional component is mountable within the exterior recess section while the pre-heater assembly is already mounted in the interior recess section;
the interior recess section, the exterior recess section, the pre-heater assembly and the additional component are configured to match to one another so that the additional component is mountable within the exterior recess section while the pre-heater assembly is already mounted in the interior recess section, wherein component is a fastening element for fastening the pre-heater assembly to the mounting recess; and
the interior recess section, the exterior recess section, the pre-heater assembly and the additional component are configured to match to one another so that the additional component is mountable within the exterior recess section while the pre-heater assembly is already mounted in the interior recess section, wherein the additional component is a separation unit holder for holding a separation unit for separating the fluid in the fluid separation apparatus.

12. The arrangement of claim 1 , further comprising a fastening element configured for fastening the pre-heater assembly in the at least one mounting recess.

13. The arrangement of claim 12 , wherein the fastening element is configured to be actuable by turning to thereby fasten the pre-heater assembly in the at least one mounting recess.

14. The arrangement of claim 13 , wherein the at least one mounting recess comprises an undercut section, and the fastening element is configured to fasten the pre-heater assembly in the at least one mounting recess by attaching the pre-heater assembly to the at least one mounting recess and subsequently actuating the fastening element to thereby fasten the fastening element in the undercut section.

15. The arrangement of claim 1 , comprising an additional component configured to be mountable in and/or on the at least one mounting recess, wherein the additional component comprises:
a separation unit holder configured for holding a separation unit for separating the fluid in the fluid separation apparatus.

16. The arrangement of claim 15 , wherein the at least one mounting recess comprises an interior recess section configured for accommodating the pre-heater assembly, and an exterior recess section arranged between the interior recess section and a surrounding outside of the mounting board and configured for accommodating the additional component.

17. A fluid separation apparatus for separating a fluidic sample into a plurality of fractions, the apparatus comprising:
a fluid drive unit configured for driving a fluid comprising a mobile phase and the fluidic sample in the mobile phase;
a separation unit configured for separating the fluidic sample into the plurality of fractions; and
the arrangement of claim 1 , wherein the pre-heater assembly is configured to be connected in fluid communication with the separation unit.

18. A method for mounting components in a heating chamber for heating a fluid of a fluid separation apparatus, the method comprising:
providing a mounting board comprising at least one mounting recess, the at least one mounting recess comprising slanted surfaces forming a V-shape; and
mounting a pre-heater assembly to the at least one mounting recess, the pre-heater assembly configured for heating the fluid upstream and/or downstream of a separation unit of the fluid separation apparatus, the pre-heater assembly comprising slanted surfaces forming a V-shape,
wherein the slanted surfaces of the pre-heater assembly are complementary to the slanted surfaces of the at least one mounting recess such that the pre-heater assembly and the at least one mounting recess have corresponding lateral surfaces substantially covering each other and faces of the lateral surfaces are pressed against each other.

19. The method of claim 18 , wherein:
the at least one mounting recess comprises an interior recess section, and an exterior recess section arranged between the interior recess section and a surrounding outside of the mounting board;
mounting the pre-heater assembly comprises mounting the pre-heater assembly in the interior recess section; and
the method further comprises mounting an additional component to the exterior reces
