The Application of the B&W Tek i-Spec Visible-NIR Spectrometer to Condition Monitoring of Oils and Lubricants: Example Hydraulic Fluids

Optical spectral measurements have been used for decades for the identification, characterization and quality assessment of oils and lubricants. The most common spectroscopic method, which has been well documented since the 1960s, is infrared spectroscopy, today used in the form of FTIR. In this application note, the i-Spec system is considered as a complementary tool to FTIR for condition monitoring of fluids outside of the traditional laboratory environment.

Rapid Analysis of Textiles with Portable Near Infrared Spectroscopy

NIR spectroscopy is a green technology that is non-destructive, efficient, rapid and accurate, with no sample preparation needed. When applied to the rapid identification of textiles, it removes the need for strong chemical solvents to dissolve the samples, meaning that there is no destructive sampling, greater safety for the operators, and no hazardous materials output into the environment.

Choosing the Most Suitable Laser Wavelength For Your Raman Application

Dispersive Raman spectroscopy has increasingly been implemented for material identification due to its portability and sampling flexibility. When choosing a Raman instrument, a primary concern is the wavelength of the laser that is integrated into the Raman spectrometer system. Though the Raman shift of any material is only related to the material’s specific chemical structure and is independent of the excitation wavelength, different wavelengths have their strengths and weaknesses.
