Fast Ingredient Analysis of Edible Oils Using a Portable Raman Spectrometer

B&W Tek, Inc.
18 Nov 2014

Edible oils are not only a major source of nutrition but also a key basic material in the food industry. Vegetable oils are increasingly important because of their high content in mono- and polyunsaturated fatty acids in comparison with animal fats. In this application note, the main ingredients of olive oil, camellia oil, arachis oil, sunflower seed oil, and colza oil are analyzed using a portable Raman spectrometer combined with chemometrics software from B&W Tek.

i-Raman ‒ High Resolution TE Cooled Raman Spectrometer

B&W Tek, Inc.

The i-Raman® is unique for its high resolution combined with field-portability, with performance comparable to large bench-top Raman systems and weighing less than 7lbs The i-Raman® is equipped with B&W Tek’s patented CleanLaze® technology for exceptional laser stabilization and narrow linewidth. Other features include a spectral resolution as fine as 3cm-1, wide Raman shift coverage up to 4000cm-1, and a TE cooled 2048 pixel CCD array. With a convenient fiber optic interface, it can collect data to within 65cm-1 of the Rayleigh Line.It is unique for its high resolution combined with field-portability, with performance comparable to large bench-top Raman systems and weighing less than 7 lbs. The system’s small footprint, lightweight design, and low power consumption provides research grade Raman capabilities anywhere!The i-Raman offers 532nm, 785nm, and 830nm excitation wavelength options. All i-Raman systems feature deep TE Cooling, allowing the maximum effective integration to be 4 minutes. This makes the i-Raman ideal for demanding applications involving low concentrations and weak Raman scatterers.i-Raman ‒ High Resolution TE Cooled Raman Spectrometer Features: Patented CleanLaze® Technology for Laser Stabilization 175cm-1 of the Rayleigh Line (65cm-1 Option Available) Fiber Optic Interface for Convenient Sampling Spectral Resolution of 3cm-1 Wide Raman Shift Coverage TE Cooled 2048 Pixel Array
