Analysis of Organotins Using Large Volume Injection Gas Chromatography-Mass Spectrometry Selected Ion Monitoring
This article will discuss current European environmental quality standards and review traditional methods for analysing organotins and their limitations.
Organotins have been used in the shipping industry as protective paint coatings applied to the hulls of ships. However, trisubstituted organotin compounds decompose in water in a stepwise manner to less substituted compounds, down to inorganic tin. As a result of their toxicity at low concentrations, trisubstituted organotin compounds are regulated through global environmental quality standards. To ensure regulatory compliance and environmental protection, the industry must perform rigorous monitoring of these compounds. This article will discuss current European environmental quality standards and review traditional methods for analysing organotins and their limitations. An application example will be used to demonstrate the analytical capabilities of large volume injection gas chromatography-mass spectrometry selected ion monitoring (LVI GC–MS SIM) for analysing organotins.
Identifying and Rectifying the Misuse of Retention Indices in GC
December 10th 2024LCGC International spoke to Phil Marriott and Humberto Bizzo about a recent paper they published identifying the incorrect use of retention indices in gas chromatography and how this problem can be rectified in practice.
Overcoming Common Challenges to Determine Residual Impurities Using IC in APIs with Limited Water
December 10th 2024Organic solvents are generally not compatible with ion chromatography (IC) systems. The approach presented here assists the use of organic solvents for sample preparation and provides a mechanism for the removal of the organic solvents from the chromatographic flow path.
Investigating the Influence of Packaging on the Volatile Profile of Oats
December 10th 2024In the testing of six different oat brands, headspace sorptive extraction and comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC–TOF-MS) reveal how various packaging types can affect and alter the oats’ volatile profile, underscoring the potential impact of packaging on food quality.
