Sampling and detection kit for chemical and biological materials

An analysis device for detecting one or more volatile organic compounds (VOCs), comprising:

• a housing, said housing including a camera and a processing unit, said processing unit operatively connected to said camera to control operation of the camera;
• and
• a sampling cartridge, said sampling cartridge comprising:
• a body;
• a mechanism for attaching the sampling cartridge to the housing;
• a sample collection pad inside said body for collecting a sample which generates VOCs;
• and
• a colorimetric sensor array (CSA) between the sample collection pad and the housing, wherein said CSA includes a plurality of dye dots and each of said dye dots includes a different colorimetric dye configured to react with different VOCs on the sample collection pad with a change in color;
• and
• wherein the camera collects images of the CSA for processing by the processing unit to analyze and identify the VOC based on the color changes of the dye dots, and wherein said processing unit is configured for comparing the images from the CSA to a library of images of CSAs reacting to known compounds, wherein the comparison is based on a baseline image being used for comparison with subsequent images taken automatically at programmed intervals.
