Polar and non-polar components in Fast Pyrolysis Bio-Oil in relation to REACH registration.

concentration of the calibration points are plotted and the concentration of furfural in the FPBO can then be obtained by extrapolating the furfural area and correcting for the dilution factor. [...] concentration of the calibration points are plotted and the concentration of methanol in the FPBO can then be obtained by extrapolating the methanol area and multiplying it times the dilution factor. [...] 7: A typical chromatogram of the acetaldehyde (in FPBO) analysis applying the RuG method Acetaldehyde concentration in the range of 0.01-0.90 wt% were found in the oils and there is some difference in concentration between the different types of FPBO. [...] For the RuG method the RRF was determined and for the VTT method calibration curves were prepared by plotting the areas of the standards against the concentrations. [...] Subsequently, by applying the RRF or by extrapolating the area of the phenolic peaks and correcting for the dilution the concentration of individual phenolics could be obtained.
