SAMPLE SIZE CHROMATOGRAPHY DEVICE

A chromatography device disclosed by the present invention has a housing formed from an upper housing ultrasonically welded to a lower housing, a compression extension and a boss located inside of the housing, wherein the media is disposed between the compression extension and the boss, such that a perimeter of the media is compressed between the compression extension and the boss, thereby forming a liquid impermeable seal along the perimeter after the upper housing is ultrasonically welded to the lower housing. 本发明公开了一种色谱装置，该色谱装置具有通过将上部壳体超声焊接到下部壳体而形成的壳体。压缩延伸部和凸台位于该壳体的内部，其中介质被设置在压缩延伸部和凸台之间，使得该介质的周边被压缩在压缩延伸部和凸台之间，从而在上部壳体被超声焊接到下部壳体之后沿着周边形成液体不可透过的密封部。
