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.

This application note describes the analytical workflow developed for the analysis of water samples over an extended period using the latest innovations in ICP-MS instrumentation. The innovations specifically highlighted in this app note are the next generation Argon Gas Dilution accessory, which simplifies the analysis of high matrix samples allowing direct analysis without prior manual diution; the HAWK consumables and maintenance assistant within the Qtegra ISDS software; the new Easy-click compact (ECC) peristaltic pump; and the new Thermo Scientific autosampler, the iSC-65 autosampler.

This application note details the analysis of various brine solutions, containing up to 25% w/w dissolved salt, using robust ICP-MS instrumentation operated with the next generation Argon Gas Dilution (AGD) accessory. These high matrix samples were analyzed directly, without manual dilution, eliminating error prone and time- consuming preparation and handling steps. The developed method was rigorously tested for performance and reliability demonstrated through excellent quality control, matrix spike and internal standard recoveries for an analysis of 120 samples of 2.5% w/w brine solution.

This application note discusses a total workflow for the analysis of water and wastewater samples using the latest innovations in ICP-MS instrumentation which offers a comprehensive solution for effective and trouble-free analysis of samples containing high dissolved solids. The complete method quality control protocol was included in this study to ensure accuracy, precision, and reproducibility of an extended analysis consisting of 600 samples.
