Rapid Classification of Beef Aroma Quality Using SIFT-MS

Application of multivariate statistical analysis to a combined data set demonstrated that SIFT-MS discriminates premium quality beef from eight sensory defects, and, therefore, could be applied as an instrumental grading tool, obviating sensory panel grading.

High Performance ICP-OES Sample Introduction: How to Choose and Use the Best Nebulizer for Your Analysis

Nebulizer selection is a critical but often overlooked aspect of inductively coupled plasma–optical emission spectroscopy (ICP-OES) analyses. There are many different nebulizers available for ICP-OES, and choosing the optimal one can be confusing and difficult. To achieve peak performance from your ICP, it is essential to choose the proper nebulizer based on your sample types in addition to any necessary accessories to maintain long-term performance. In this study, we compare the performance of Glass Expansion’s most popular concentric nebulizer designs for ICP-OES applications as well as a parallel-path nebulizer from another vendor, providing a complete selection guide based on performance and design.

SEC–ICP-OES Hyphenation: Speciation and Quantification of Polydimethylsiloxanes at Trace Levels

Polydimethylsiloxane (PDMS) compounds are ubiquitous; thus it is challenging to develop analytical methods that ensure their absence. A newly developed method combining sizeexclusion chromatography with inductively coupled plasma–optical emission spectroscopy makes it possible to quantify ultratrace levels of PDMS in volatile and nonvolatile organic solvents. A complete range of molecular weights can also be distinguished with this approach.
