1. A method of testing for the presence of asbestos, comprising:
taking a sample;
mixing the sample with a test composition to form a mixture, the test composition including
a fluoro compound comprising at least one of hexafluoro titanium di-ammonium, potassium hexafluoro zirconate, ammonium hexafluoro phosphate, ammonium hexafluoro stannate, ammonium hexafluoro germanate, ammonium tetrafluoro borate or ammonium heptafluoro tantalite, and
a fluorine scavenger compound;
obtaining an FTIR spectrum of the mixture; and
examining the FTIR spectrum for a peak at 873.6 inverse centimeters (cm−1).
