All food products should be of trustworthy quality and purity, not just for consumer safety but also to ensure product authenticity and the accuracy of product labels. This is especially important for olive oils, of which there are many different types based on quality (e.g. refined, extra virgin, etc.). In some circumstances, high quality oils can be adulterated with other lower quality olive oils or oils from a different source, like canola or soybean.

Thermochromic materials are substances which reversibly change color with temperature and are commonly used in a variety of products like textiles and smart windows, among other materials.

Pt-Co, Hazen, and APHA color are three different terms referring to the same color analysis procedure often used to assess the yellowness of water samples. In this analysis a mixture of cobalt chloride and potassium hexachloroplatinate(IV) is prepared and subsequently diluted by varying amounts to form an array of yellow to almost colorless standards, as described in ASTM D1209 and ISO 6271:2015.

The human eye is able to collect the light reflected off a surface, leading to the perception of color. Since the color range we can see covers the aptly named visible range of the electromagnetic spectrum (400 – 700 nm), UV-Visible spectrophotometers are often used for color analysis.

Elemental analysis is crucial in a wide variety of applications from detecting toxic elements within the environment, to ensuring drinking water is safe for human consumption, to food product safety. ICP-MS—able to measure an atom’s mass—offers low detection limits in the range of parts per trillion (ppt), making it a widely used method that can detect toxic elements well below regulatory limits. This paper expands upon how new ICP-MS technology can meet the challenges associated with heightened demands for element analysis and the hurdles laboratories face when analyzing high-matrix samples.

In this exclusive Spectroscopy interview, John Richmond and Tom Dearing of Thermo Fisher Scientific discuss the company’s Raman technology and the latest trends for process monitoring across various applications.
