1 SUPPLEMENTAL INFORMATION Evlution of Modified Boehm Titrtion Methods for Use with Lignoellulosi Biohrs Rivk B. Fidel, Dvid A. Lird*, Mihel L. Thompson Deprtment of Agronomy, Iow Stte University, Ames, IA, 50011, USA *Corresponding uthor Tel.: ; Emil: Contents (6 pges totl) Figure S1 Funtionl group onentrtions of CE500 iohr s mesured with ll three methods nd ll retnts, nd sornes of the prepred extrts t 250 nm (A 250 ). Figure S2 Comprison etween titrtion urves mde y Goertzen et l (2010) nd this study. Figure S3 Comprison of funtionl group onentrtions etween orse (> 0.5 mm) nd fine (< 0.5 mm) frtions of RO500 FP iohr. Figure S4 Comprison etween the numer of times 7 ml liquots of 0.05 M NHCO 3 solution were run through n ENVI-Chrom P solid phse extrtion rtridge nd the mount of NOH needed to k-titrte n idified nd sprged 5 ml liquot. Figure S5 Funtionl group onentrtions of slow pyrolysis nd gsifition iohrs mesured using the sprge-rium-rtridge method. Figure S6 A 250 vlues of extrts from slow pyrolysis nd gsifition iohrs. S1

(2010) showed tht, following 2h of sprging with N 2 gs, further degssing during the titrtion n remove dditionl CO 2 from solution nd therey prevent positive is (CSF is defined s Cron Surfe Funtionlities). Positive is ws indited y the presene of n dditionl infletion point. () In this study, no evidene of dissolved CO 2 ws found fter 2h of sprging without further degssing during the titrtion.

5 Figure S4 Comprison etween the numer of times 7 ml liquots of 0.05 M NHCO 3 solution were pulled through stk of two ENVI-Chrom P solid phse extrtion rtridges nd the mount of NOH needed to k-titrte n idified nd sprged 5 ml liquot. Aliquots were idified using 2:1 volume rtio of 0.05M HCl to rtridge-treted smple, then sprged for 2h. Eh dt point represents single mesurement (R 2 = 0.999, p = 0.001). S5
