Determination of the Degree of Cure of a Varnish
January 8th 2016Modern paints and varnishes are complex mixtures and the optimization of the material properties is an important task. One of the most essential variables is the curing which should in most cases take place in a reasonably short time span that can range from a fraction of a second to many days. It is difficult to evaluate the degree of the curing and its completeness by visual inspection. Therefore, an unbiased and reliable quantitative analysis is needed in quality control but also in R&D to optimize the varnish or the curing method respectively.
Raman Spectroscopic Evaluation of Bones
December 16th 2015Raman spectroscopy provides data on bone mineral crystallinity, carbonate to phosphate ratio and extent of collagen cross-linking, all compositional information that is intimately related to biomechanical characteristics of this unique material.

Measurement of Indocyanine Green Fluorescent Dye in the Long Wavelength Region
December 12th 2015Indocyanine Green fluorescent dye displays fluorescence in the near infrared region in the vicinity of 810 nm; however, measurement in wavelength regions greater than 750 nm has been difficult. This note presents an example of measuring Indocyanine Green with good sensitivity while obtaining corrected spectra in real time.
Bringing New Life to Old Arteries with Oxygen
November 13th 2015In this application note, we focus on the peripheral artery disease (PAD) and its treatment, utilizing NeoFox optical oxygen sensor system to demonstrate how oxygenation increases stem cell survival and leads to improved therapeutic outcomes for PAD patients.
Identification of Inorganic Filler Materials in Polymers
October 14th 2015Combined investigations in the far and mid infrared region in a single scan can offer great value for the analysis of polymeric materials. With the use of optical components optimized for combined FIR-MIR spectroscopy, consisting of a wide range mid to far IR beamsplitter and detector, the investigation of both spectral regions in single step is possible.

In-Field Measurements of Major Elements and Base Metals with Handheld LIBS
October 1st 2015Data for a handheld LIBS device (SciAps Z-500) is presented demonstrating in-field measurement of several elements critical for geochemical applications. In some cases these elements have never before been measured with a handheld device.
Measurement of Enhanced Specular Reflector Films Using LAMBDA 1050 and URA Accessory
September 10th 2015Learn how the spectral characterization of Enhanced Spectral Reflector (ESR) films is an important step in developing new novel applications for these unique materials. From enhanced skylights to brighter displays ESR films play an important role.
Infrared Transmission Measurements of Diffuse Samples
September 1st 2015Measuring the transmission of diffuse samples such as paper or filled polymer films requires an integrating sphere to obtain accurate transmission values and useful chemical information, because the IR light is scattered as it passes through the sample. An integrating sphere serves as a collection device for the scattered light.
Rapid Evaluation of Extra Virgin Olive Oil Using Fluorescence Spectra
September 1st 2015Strict production requirements, consumer demand, and at times poor harvests, result in high prices and can limit the supply of EVOO. Consequently, EVOO is susceptible to economically motivated adulteration with less expensive oils and claims of authenticity continue to be a concern.
Integrating FT-IR and FT-Raman for the Pharmaceutical Industry
September 1st 2015Infrared and Raman spectroscopy are critical analytical techniques in the pharmaceutical industry, used for the structural elucidation and characterization of organic materials such as new drug candidates, impurities, metabolites, and excipients.
Modeling and Monitoring of Time-Dependent Processes with Spectroscopic Techniques
September 1st 2015Spectroscopic techniques have a long history as quantitative methods for on-line and at-line use in a wide range of industries, where, in many cases, they are more accurate than the reference methods. These processes are typically continuous, but time-depending processes such as batch processes are widely used in many industries.
