Abstract: Disclosed, is a dosing apparatus [1] which is configured to provide a predetermined amount of material from one vessel to another vessel. The dosing apparatus [1] may comprise a dosing head having a dosing tube [9] and a dosing rod [12] which is movable within said dosing tube [9]. The dosing rod [12] may comprise a dosing chamber [10] which may be filled with a predetermined amount of material. Also described, is a method of dosing which utilizes the dosing apparatus [1] disclosed. In some embodiments, the method may comprise providing a dosing apparatus [1], extending the dosing rod [12] with respect to the dosing tube [9], loading the dosing chamber [10] with a predetermined amount of material, and, retracting the dosing rod [12] with respect to the dosing tube [9] to close the dosing chamber [10]. One or more air and/or liquid cleaning steps may be employed, wherein a cleaning unit [17, 117] may be utilized to clean the dosing rod [12] and/or a funnel [4].

Abstract: Disclosed, is a sample preparation apparatus which is configured to prepare a material sample suitable for X-ray diffraction. The apparatus comprises a dished sample holder bottom configured to fit within an annular sample holder. The dished sample holder bottom has a concave dished surface which is adapted to distribute sample material under pressing forces. A method of preparing a material sample suitable for X-ray diffraction is also disclosed. The method comprises dosing a dished sample holder bottom which is configured to fit within an annular sample holder with sample material, wherein the dished sample holder bottom preferably has a concave dished surface which is adapted to distribute sample material under pressing forces.

Abstract: Disclosed, is a sample preparation apparatus (6B) which is configured to prepare a material sample (900′) suitable for X-ray diffraction. The apparatus (6B) comprises a dished sample holder bottom (500) configured to fit within an annular sample holder (400). The dished sample holder bottom (500) has a concave dished surface (501) which is adapted to distribute sample material (900) under pressing forces. A method of preparing a material sample (900′) suitable for X-ray diffraction is also disclosed. The method comprises dosing a dished sample holder bottom (500) which is configured to fit within an annular sample holder (400) with sample material (900), wherein the dished sample holder bottom (500) preferably has a concave dished surface (501) which is adapted to distribute sample material (900) under pressing forces. A new leveling device design tool (FIG. 12) is also disclosed. The leveling tool minimizes surface contact effects by penetrating the core of the sample and providing random sample grain orientation while evenly distributing material throughout the sample holder bottom. The sample material (900) is lightly pressed, and sample material (900) is distributed within the dished sample holder bottom (500) by virtue of the concave dished surface (501).
