A new brochure from Wilks Enterprise Inc (USA) features two easy-to-use mid-infrared analysers for various biofuels analyses that are ideal for use in production facilities and for fuel blending at distribution centers. These instruments have been specifically designed for on-site analysis of such measurements as biodiesel in diesel, ethanol in gasoline, water in ethanol, total gylcerides, FFA’s in feedstock and water in feedstock. They can be operated by personnel having little or no knowledge of infrared analytical techniques.
The first is the InfraCal Filtometer. This is a low-cost, single wavelength analyser that is ideal for measuring the blend ratio of
biodiesel in diesel fuel or ethanol in gasoline. Since tax incentives and government regulations are often based on % biofuel, it is
important to have an accurate measurement method. The InfraCal Filtometer is compact and portable, yet easy for non-technical
personnel to operate. It gives a direct readout in % biodiesel or % ethanol allowing the user the capability to measure the blend ratio on-site at a manufacturing or distribution facility.
The second instrument is the InfraSpec VFA-IR Spectrometer that is a spectral range analyzer capable of monitoring more than one component. It will measure the % biodiesel in diesel fuel as well as total glycerides during the biodiesel reaction process.
Using the InfraSpec Spectrometer for making pass/fail determinations for total glycerides can significantly reduce analysis time and
increase reactor throughput by as much as 20%. The InfraSpec can also be used for testing free fatty acids and water in the biodiesel
feedstock. The InfraSpec VFA-IR Spectrometer is compact, portable and has a simplified PC interface for non-technically trained personnel. This provides the user with the capability to easily make on-site measurements in the processing plant, as well as in the QC laboratory.
The InfraSpec Spectrometer represents a new concept in mid-infrared instrumentation and is based on patented design.
It enables the operator to obtain infrared spectra on a variety of components in the biofuels manufacturing process at a fraction of
the cost of an FT-IR spectrometer.
