Blood contamination detection in biological fluids. I MALDI-TOF MS spectra of CSF. ae Artificially Hb-contaminated CSF. α and β denote the Hb α- and β-chains (15.1 and 15.9 kDa, respectively). f Negative control-uncontaminated CSF. II MALDI-TOF MS spectra of CSF. ac Contaminated CSF samples. d Uncontaminated CSF sample. III Spectrophotometric analysis of CSF (515–615 nm). a The 3.0-nM hemolysate absorbance spectrum. b, c Contaminated CSF. d Uncontaminated CSF. IV MALDI-TOF MS spectra of FF. a, b Contaminated FF samples. c Uncontaminated FF sample
