Calibration transfer of near‐IR partial least squares property models of fuels using virtual standards

摘要: Partial least squares (PLS) models of 10 important jet and diesel fuel properties were built using spectra from a master near-IR dispersive instrument then subsequently transferred to secondary via novel calibration transfer method virtual standards slope-bias correction. Implementation the requires that only seven neat solvents be acquired on instruments. The are used digitally replicate set generate standards. Comparison PLS predictions for provides simple but effective correction transfer. include American Petroleum Institute gravity, % aromatics, cetane index, flashpoint, hydrogen content, saturates, distillation temperatures at 10%, 20%, 50%, 90% volume recovered. Transfer error was lower than either pure with or piecewise direct standardization spectra. higher when actual fuels calibration. use eliminates need maintain complex future transfers.
