Comparison of gravimetric and spectrally acquired water content.
Raman samples were scanned on convectively dried abiotic 3MM paper. Maximum peak intensity ratios of 3350 and 2950 wavenumbers were correlated to gravimetrically obtained total water content of similar paper samples. Values were obtained for samples dried at equal convective drying times. Linear regression fitting shows a strong correlation (R2 = 0.95) between the two water content acquisition methods used.
