title: A rapid microtechnique for the detection of trace metals from gunshot residues.
abstract: The most important facts and advantages of this method are as follows. 1. A simple separation and identification scheme for metals considered characteristic of gunshot residues was developed. 2. The apparatus used is inexpensive, simple, extremely versatile, and has moderate sensitivity. 3. Blanks of background ions present do not interfere with the test, but warrant consideration. 4. Few reagents are needed, and the results are preservable.
