(Acetoxy-)valerenic acid and total essential oil content are important quality attributes of pharmacy grade valerian root (Valerianae radix). Traditional analysis of these quantities is time-consuming and necessitates (harmful) solvents. Here we investigated an application of attenuated total reflection Fourier transform infrared spectroscopy for extractionless analysis of these quality attribu...

A novel analytical platform combining infrared attenuated total reflection (IR-ATR) spectroelectrochemistry (SE) with atomic force microscopy (AFM) using a boron-doped diamond (BDD)-modified ATR crystal is presented. The utility of this combination is demonstrated investigating the electrodeposition of a polymer film via IR spectroscopy, while the surface modification is simultaneously imaged b...
