ABSTRACT:
A method and apparatus for adsorption and detection of adsorbents or analytes. The method and apparatus can be employed in the field for rapid adsorption of analytes and is particularly useful for detection of mycotoxins. A sample to be analyzed is prepared in solution and placed in a test tube. A tube-like adsorption column having a seal and a valve member is forcefully fed into the test tube to force solutions through the valve member into the column and through a filter and adsorbent to trap interference. The semi-purified solution may then be analyzed for the presence of analytes. The column with the purified solution may be further employed with a second smaller adsorption column similarly equipped with a seal and valve member fitting within the first column. In similar fashion the second column may be forced into the first column to expel the solution therein into the second column and through one or more selective adsorbents for different analytes such as one or more mycotixins. Detection of the adsorbed analyte may be made by shining a fluorescent or "black" light on the adsorbent which fluoresces to indicate presence of the analyte.
