Chemometric Modeling of Methanol in Tertiary Mixtures Using a High Resolution Portable Raman Spectrometer

16 Sept 2014

This application note looks at the use of B&W Tek’s advanced chemometric modeling software BWIQTM to determine unknown methanol concentrations in a tertiary mixture of methanol, acetonitrile, and water.

BAC151B ‒ Raman Video Microsampling System

B&W Tek, Inc.

The BAC151B Raman video microscope sampling system allows you to convert any of B&W Tek's Raman systems into a Raman microscope It is compatible with our laboratory Raman probes and is designed to provide you with the highest level of flexibility and sampling utility. The BAC151B’s optional dual laser wavelength configuration allows you to use one port with two different input laser wavelengths. If you already have both a 532nm and a 785nm Raman system, you only need one BAC151B to use with both systems. We also offer individual 532nm, 785nm, and 1064nm versions.The integrated camera facilitates precision Raman sampling through BWSpec™, which allows for laser beam tracking and image capturing. With tripod accessories available, the microscope head can be mounted to the tripod easily as well.BAC151B ‒ Raman Video Microsampling System Features: Tripod Mounting Accessories with 1D, 2D, and 3D Adjustment Compatible with All B&W Tek Raman Systems Accepts Standard Microscope Objectives Video Camera for Sampling Viewing Coarse and Fine XYZ Adjustments Dual Laser Wavelength Port

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
