ABSTRACT:
The present invention involves a unitized dry reagent test device and method for removing the interference caused by suspended particulate materials in the calorimetric determination of analytes in samples containing such materials. More specifically, the testing methodologies of the present invention comprise the use of a multilayer reagent impregnated matrix having known particulate removal characteristics attached to a test fluid impervious support means which has known light transmission characteristics. On-site or field testing of soil samples is an advantageous and representative application of the devices and methods of the present invention.
