Document Summary

A technique known as gas-chromatography used with mass spectrometry was used to detect drugs in the body system: chromatography: used to separate compounds, mass spec. is then used to analyze the compound. Isotope ratio mass spectrometry (irms): used to tell the origin of molecules of the doping agent. Slightly lower ratios of c13/c12 will indicate that an athlete is using synthetic testosterone. Kinetic molecular model: states that the higher the temp. the faster the particles move. Substance: refers to a pure and single form of matter. Chemical compounds: molecules or ions composed of atoms of 2 or more diff. elements in fixed and definite proportions ex. pure substances like testosterone, sugar, salt, and water. Chemical properties: describes its characteristics with its reaction with others and what happens if it does react. Physical properties: used to characterize substances through colour, state, melting point, boiling point, & density. Isotopes: atoms with different # of neutrons but are of the same element.
