1. A portable chemical analytical apparatus to analyze a test swipe, comprising:
- a heater to warm the test swipe to various predetermined temperatures at various hold times;
a clamp to secure the test swipe to the heater;
one or more pumps to dispense one or more chemicals onto the test swipe from a disposable cartridge;
a fan to remove chemical vapors rising a predetermined distance from the test swipe but leaving vapors immediately in contact with the swipe; and
a camera to capture an image of the test swipe for analysis and for real-time viewing by the operator to provide secondary level of assessment.

24. A method to analyze a swiped sample to identify a chemical composition, comprising:
-
automatically pumping a series of chemical solution agents into the swiped sample without dripping; heating the swiped sample to one or more predetermined temperatures and hold times to optimize and accelerate the chemical reactions; capturing one or more images of the chemical reaction; sending the images to the a display screen for operator observation; and analyzing the images to identify the chemical composition based on a chemical reaction and sequence of occurrence and database.
