Abstract:
A method of analyzing a sample comprising the steps of:exposing the sample to an excitation radiation having a wavelength, &lgr;ex, thereby generating an emission radiation having a wavelength, &lgr;em; scanning the wavelength of the excitation radiation and the wavelength of the emission radiation to collect a spectrum; and correlating the spectrum to a condition of the sample, wherein said excitation and emission wavelengths are varied according to the formula: &lgr;em=&lgr;ex+&Dgr;&lgr;, wherein &Dgr;&lgr; varies and &Dgr;&lgr;>&Dgr;&lgr;min, wherein &Dgr;&lgr;min is a minimum separation between the excitation wavelength &lgr;ex and the emission wavelength &lgr;em.
