Abstract

A method (100) of performing spectral analysis on a sample (220) identified within a gas turbine engine (10). The method (100) involves: obtaining (102) an optical spectrum (240) of the sample (220); normalising (104) the optical spectrum (240) to obtain a normalised optical spectrum (301); selecting (106) a characteristic parameter that characterises the normalised optical spectrum (301); determining (108) a characteristic parameter value associated with the normalised optical spectrum (301) based on the characteristic parameter; comparing (110) the characteristic parameter value with one or more predetermined reference values corresponding to the characteristic parameter; and determining (112) a presence of at least one compound in the sample (220) based on the comparison between the characteristic parameter value and the one or more predetermined reference values. The method can determine whether there is a need to disassemble the gas turbine engine for maintenance.
