Spectrometers contribute to green revolution

Share this on social media:

Aspectrics’ encoded photometric near infrared (EP-NIR) spectrometers have found a use in measuring the composition of biodiesel blends– the new ‘green’ fuel that is rapidly gaining popularity.

The MultiComponent 2750 EP-NIR analyser can now grade the fuel based on an international system – the B factor – that determines the proportion of biodiesel and petroleum diesel in a fuel.

The spectrometer must be coupled to an external halogen NIR source and transmission probe. Once calibrated, its readings have a statistical confidence level of 99.9.

Biodiesel., made from vegetable oils, is biodegradable, non-toxic, and reportedly produces around 60 per cent less net carbon dioxide emissions than petroleum diesel.
