Abstract
An improved field-test method and apparatus for the detection of asbestos by detecting magnesium or iron is described wherein all of the reactions of the test are performed in one reaction tube or column. The method includes the steps of placing a sample in the tube, washing the sample in the tube, adding acid reagent to the sample, and adding a color reagent to the sample in the tube to indicate qualitatively if asbestos is present in the sample. The apparatus is in the form of a compact kit containing multiple columns with caps and other labware needed for the test.
