(a) Selected aqueous unsubtracted FTIR spectra of various n-octyl-β-D-glucoside standards (top trace, 100 mM n-octyl-β-D-glucoside; bottom trace, 10 mM Tris–HCl pH 7.5. (b) Aqueous buffer-subtracted FTIR spectra of n-octyl-β-D-glucopyranoside standards (baseline-corrected between 1187 and 947 cm−1). The concentration of n-octyl-β-D-glucopyranoside in each standard is (from top to bottom): 200, 100, 50, 25, 12.5 and 6.25 mM. (c) n-Octyl-β-D-glucopyranoside standard curve calculated using the spectra in (b). |
