Underpinning the study is the researcher’s use of Agilent’s specialized Fourier-transform infrared (FTIR) spectroscopy technology. Agilent has developed a prototype sampling approach that enables researchers to work non-invasively, and with speed and accuracy. This technology, built around Agilent’s 4300 Handheld FTIR, is already being used in studies for direct skin measurements, where it provides higher-quality data more reliably when compared to prior methods....
