With global concerns about food quality and food safety continuing to garner attention, it is important for both manufacturers and regulatory bodies to have robust analytical instrumentation and methods to ensure accurate and precise results. For the measurement of inorganic elements and nutrients, sample preparation can be of critical importance to the quality of the analysis. Here we discuss the process of sample preparation and analysis, tools and techniques for the measurement of inorganic elements in...Read More
This presentation outlines how some innovative Agilent products can help improve the performance and productivity of PerkinElmer ICP-OES and ICP-MS systems. We’ll illustrate the performance advantages by comparing performance indicators such as Limit of Detection, wash-out and memory effects, and sample to sample analysis times.Read More

A new quantitative method of analysing the biodiesel in a diesel-biodiesel blend using proton nuclear magnetic resonance (NMR) spectroscopy has been developed by researchers in Brazil. The resulting spectra are subjected to a univariate calibration in which the integrals of the spectra are considered. Statistical comparison with infrared (IR) spectra corroborate the findings.

The Ghent Altarpiece was a family affair painted around 1432 by Flemish/Early Netherlandish artist Jan van Eyck and according to art historians probably his brother Hubert. Now, chemical imaging based on element-specific X-ray analysis of a large area of the work has revealed the original paint layers and assisted in cleanup and conservation.View All Ezines
