Biofuels such as biodiesel and bioethanol are now the main alternatives to fossil fuels in one of the most pollutant human activities: transportation. The authors report on the use of process analytical technology for mapping raw materials, fingerprinting process trajectories, and calibrating for the most important quality specifications, both for individual chemical and physical attributes or for combined quality attributes, thusleading to more consistent and economically viable processes.

Hitachi introduces two new versions of the U-4100 UV-Vis-NIR Spectrophotometer: the Standard Solid Sample System and Large Solid Sample System. These new systems use PMT and InGaAs detectors, providing increased sensitivity in the range of 850–1700 nm. This results in reduced noise, making the instrument suitable for the measurement of low transmitting/reflecting anti-reflection coatings.
