Figure 1From: Metabolism of fatty acids and lipid hydroperoxides in human body monitoring with Fourier transform Infrared Spectroscopy(A). In situ measurement system for human lip surface with newly developed FTIR-ATR adaptor. The probe diameter is 2 mm. Here we call this system CISME (Corneum Infrared Spectrum for Metabolic Experiments) measurement system. Fig. 1 (B). Illustration of extraction procedure for lip lipids using PVDF membrane and EPI solvents. Initially the washed lower lip was wiped at least 4 times with partially wetted PVDF membrane by EPI-solvent.Back to article page
