    • An assay tray assembly and an assay tray primarily for chromatographic analysis has a plastics moulded test tray 1 mounted on a plastics moulded collection tray 72, The test tray has a spaced array of chambers 3 disposed as per a microtiter plate, Each chamber has a bottom outlet port 5 formed by a flange 8 which retains within the chamber a chromatographic medium to which test liquid deposited in the chamber is to be subjected for the percolate or eluate liquid to emerge from the respective outlet ports, The collection tray 72 has a spaced array of wells 16 disposed as per a microtiter plate to correspond with the chambers 3 and the tray 14 is mounted on the tray 72 for each chamber to communicate with a corresponding well 16. Each chamber 3 has a tubular spigot part 12 which extends into the respective well 16 to alleviate cross contamination of the liquid derived from the outlet ports 5.The depth of entry of the tubular spigots 12 into their respective wells 16 is restricted by abutment between the bottom of the test tray with the top of the collection tray, The volume of each well 16 beneath the tubular spigot it receives is adequate to accommodate all of the eluate or percolate derived from the chamber 3 with which it communicates to alleviate liquid on the spigot parts from dripping into wells with which those tubular spigots are not associated (and thereby cause cross contamination) when the trays are separated for analysis of the percolate or eluate.
    • 主要用于色谱分析的分析托盘组件和测定托盘具有安装在塑料模制收集托盘72上的塑料模制测试托盘1.测试托盘具有根据微量滴定板布置的间隔开的腔室阵列3,每个腔室具有底部 出口端口5由凸缘8形成,该凸缘8在腔室内保留色谱介质,沉积在室中的测试液体将经过渗透液或洗脱液从相应的出口出口。收集托盘72具有间隔开的阵列 根据微量滴定板布置以与腔室3和托盘14对应的孔16安装在托盘72上,用于每个室以与相应的孔16连通。每个腔室3具有管状插口部分12,其延伸到相应的孔 井16以减轻来自出口5的液体的交叉污染。管状插口12进入其各自的孔16的深度受到邻接 测试托盘的底部与收集托盘的顶部之间的每个孔16的容积在其所接收的管状插口下面的容积足以容纳所有来自腔室3的洗脱液或渗透液,其与其连通以减轻液体 在这些插管部分上滴入到那些管状插口不与之相关联的孔中(并且由此引起交叉污染),当塔板被分离以分析渗滤液或洗脱液时。
