Compact Spark spectral sensor measures Vis-NIR absorbance of hemoglobin – and more

Optimizing oxygen delivery improves stem cell treatment of peripheral artery disease.

Banknotes, passports and professional licenses have high value and are at risk for counterfeiting, tampering and forgery.

Even as advances in engineering technologies and manufacturing processes have lowered the cost to make and distribute products, the demand for continued improvement is as strong as ever.

NIR spectroscopy and machine vision team up for rapid grains inspection

Rapid screening for total mercury content of water, soils and fish takes to the field

Spirit Sampling for counterfeit detection and brand authentication

Raman analysis of graphene on silicon dioxide wafers

Biodiesel can be used in most diesel engines with little to no engine modification required, and can be blended with petroleum diesel fuel to provide a cleaner burning, lower emission diesel fuel.

2-Propanol is one of the most common solvents in the world, with over 2 million tons produced in 2003 (Science).

Have you ever heard that moonshine will make you go blind? Today, even your favorite, top-shelf liquor may be just as much of a risk.

While electric vehicles are becoming more mainstream the use of traditional gasoline engines will have a place in society for decades to come.

Essential oils have been used for thousands of years in many cultures for medicinal and health purposes.

In this article, we discuss how UV absorbance spectroscopy measures exhaust emissions aboard seagoing commercial vessels.

In this application note, we evaluate the effectiveness of surface enhanced Raman spectroscopy (SERS) to measure trace levels of imidacloprid, one of a class of insecticides linked to honeybee loss.

Given enough incident intensity, any laser wavelength can be used to stimulate the Raman effect.

In this whitepaper, we explore how the Spark spectral sensor bridges the gap between filter-based devices such as RGB color sensors and CCD-array instruments such as miniature spectrometers. The ultra-compact Spark provides full spectral analysis from 380-700 nm.

Gluten – a substance found in grains – is an allergen for some people. When processing gluten-free and other grains, cross contamination is a risk. This article describes how NIR spectroscopy combines with machine vision for accurate sorting of glutenous grains.

Suppliers of photovoltaic panels for the solar industry continually evaluate and analyze panel materials, seeking ways to improve efficiency and reduce costs. In this application note, NIR reflectivity of coated glass samples reveals areas of light loss and other characteristics.
