Title:
ヒートシンクを有する直接分析サンプラー
Document Type and Number:
Japanese Patent JP6723978
Kind Code:
B2
Abstract:
Sample chamber (3) comprising a cover plate (32) and a housing (30) forming a heat sink, said housing (30) including an immersion end (16) having a first opening (20) for a molten-metal inflow conduit (7) and an opposing end (18), and a first face (40) extending between said immersion end (16) and said opposing end (18), said first face (40) having a depression extending from proximate the immersion end (16) towards the opposing end (18), said depression being in direct flow-communication with the first opening (20) to receive the molten metal from the inflow conduit (7).
The cover plate (32) and the housing (30) are assembled together along a first plane (AF) to form a sample cavity including the depression such that an analysis surface of the solidified-metal sample (S) formed within the sample cavity lies in the first plane (AF). The sample cavity and the first opening (20) are aligned along a common longitudinal-axis (X) and the first opening (20) is spaced apart from the first plane (AF).
The ratio between the thermal diffusivity of the solidified-metal (S) and the thermal diffusivity of the material forming the housing (30) is between 0.1 and 0.5, the housing (30) is configured to be inseparable from the solidified-metal sample (S) and at least a portion of the housing (30) is directly adjacent to the solidified-metal sample (S) and lies in the first plane (AF).
