Bench-Top Raman Spectrometers

The Advantage series is our classic low cost and high performance bench top models with the option of 532 nm, 633 nm, 785 nm (NIR) or 1064 nm excitation. Determining the most appropriate model for your application is dependent upon the sample properties. Call us today so that we can help you determine the most appropriate analyzer for your application.

Advantage 532 Raman Spectrometer

The Advantage 532 is a low cost, high performance Raman spectrometer. It has a higher signal to noise than other Advantage series spectrometers. The signal to noise is improved because the Raman signal improves as a function of λ-4, meaning that 532 nm excitation produces signals that are nearly five times more intense than 785 nm excitation. The spectral range of the Advantage 532 extends from 200 to 3400 wavenumbers. It is easy to use on solutions, gels, powders and coatings.

Advantage 785 Near Infra-Red Raman Spectrometer

Fluorescence is a common problem in Raman spectroscopy and longer excitation wavelengths is the answer. Under conditions where fluorescence is generated, it may be intense and can overshadow the Raman features. Fluorescence emission stems from sample molecules or trace impurities that absorb the laser excitation and emit a broad background at the same energies as the Raman scattering. One way to eliminate or reduce the fluorescence emission is to select a laser excitation wavelength that does not have enough energy to excite molecular fluorescence.

The Advantage 785™ reduces competing fluorescence interference in compounds through this process. It uses a 785 nm excitation laser to reduce the fluorescence signature in samples that show strong fluorescence at shorter wavelengths. We also offer a microscope attachment, the NuScopeTM, which is used to image samples and show Raman spectra of domains in heterogeneous materials.

Advantage 1064 Raman Spectrometer

The Advantage 1064 is a high performance Raman spectrometer with the ultimate fluorescence reduction advantage.

It has the longest wavelength excitation available in a dispersive Raman spectrometer, yet it maintains the highest sensitivity available with its transfer electron InGaAs photocathode and electron bombardment CCD technology. Signal to noise is improved dramatically over FT-Raman instruments. Analyses that required hours with FT-Raman instruments can be performed in seconds with the Advantage 1064. The full range of Advantage accessories offers easy Raman measurements with solutions, gels, powders, or surfaces.

Portable/Handheld Raman Spectrometers

Inspector Raman

The Inspector Raman™ is a robust, portable Raman spectrometer that fits in your hand for analysis of solids, liquids, pastes, and slurries. This lightweight, dispersive spectrometer has no moving parts and may be used in any position. Raman spectroscopy offers the advantage of identifying various substances by their unique fingerprint, based on the chemical structure of the unknown, and can do so through walls of sealed bags, transparent bottles, flasks, vials, and ampoules without opening the container. Data is retrieved remotely with Bluetooth technology or USB with a laptop and NuSpec™ software. Spectral libraries are developed using DeltaNu's library development software for identification of unknown substances.

Raman Microscopes

ExamineR

Raman microscopy is an information rich way to characterize your samples in life sciences, geology, nanotechnology, semiconductor, forensic science and any other application where accurate chemical identification is needed.

DeltaNu presents a high performance Raman microscope at an affordable price. The ExamineR™ combines the quality of Olympus microscopy with the performance of DeltaNu's Raman spectroscopy. This combination creates a Raman microscope with outstanding imaging and spectral characteristics.

DeltaNu is the price/performance leader in Raman microscopy. Our ExamineR system comes with your choice of wavelength modules - 532nm, 785nm, or 1064nm. Our patent pending design puts the Raman module on top of the microscope and changing wavelengths is as simple as switching modules - no more tedious laser, filter, grating, and fiber optic changes like other microscopes. And, with the Raman module on top, the ExamineR's footprint is the smallest in the industry.

This system provides rapid identification with auto-focus, battery operation, on-board library matching, high capacity storage for large libraries, all in a sleek ergonomic design.

Software

NuSpec software allows users to acquire, save, archive and interpret spectral data. Data may be continuously acquired and automatically saved as ASCII xy or spc format. Spectra can be saved with an automated baseline correction algorithm or in raw form. The baseline spectra are Fourier transformed, truncated and subtracted from the raw data. Since the baseline shape is stored in the first few transform frequencies, this procedure removed much of the deleterious baseline. All spectra are referenced with the laser off to subtract ambient light. The spectral viewer allows users to interpret the most recently acquired spectrum. Spectra may be zoomed or expanded and peak heights and frequencies are reported on the screen.

The software for each instrument may vary slightly. For example, the 633 NuSpec software version has an option that automatically subtracts polarizations to provide information about molecular symmetry. The Inspector Raman version of NuSpec displays the current spectrum vs. the match spectrum and the Hit Quality Index for the top three hits.

Qualitative Analysis: Library management comes standard with the Inspector Raman and as an option for the Advantage series spectrometers. The library management software allows the users to mange a spectral library. Spectral data can be saved, searched, matched and deleted from the library.

Quantitative Analysis: The library management software package also comes with a quantitative version. Calibration files developed in Grams PLSIQ (third party software) can be transferred to the software for prediction of multiple constituents after spectral acquisition.

Third Party Software: Spectral data archived from NuSpec software can be further interpreted and manipulated with either Grams AI or ACD software.
