A Survey of Residual Solvents in Various Inks used in Consumer Product Packaging
Abstract Food manufacturers use various printing inks on their consumer product packaging. These inks are typically used on the outside of the package, but are now also included on the packaging material used in the microwave. These inks can contain residual solvents currently monitored in food and drinking water. This application note will present a survey of consumer product packaging and the ...

Using Mass Spectrometry to Monitor Reactor Solvent Composition During Solvent Swaps
ABSTRACT In the Pharmaceutical Industry it is a common practice to carry out reactions in various solvents that are chosen to aid in the reaction or separation process. There are many instances where solvents must be swapped between stages. In other instances water may be present from the reaction or from an extraction that has to be removed. These solvents are usually removed by one or more ...

Solvent Safety in Pharmaceutical Manufacturing
The manufacture of pharmaceutical products is a complex and multi-stage operation that can include processes such as blending, wet and dry granulation, milling, hot-melt extrusion, coating, andtablet pressing. Producing the exact formulation, release rate, consistency, and dosage form requires many chemical compounds and substances. Among the mare active pharmaceutical ingredients (API), the ...

Near-infrared spectroscopy (NIRS): The perfect solution to monitor purity of recovered solvents
Solvent recovery is the process of extracting useful solvents and raw materials from waste or byproduct solvents that are generated during manufacturing processes. The solvents that are used in these situations are often not disposed of or incinerated, but instead recovered and purified, as this saves considerable costs. Used solvents are mostly purified by means of distillation. Solvent ...

Don’t Let the Welding Fume Plume Make You Sick
What’s at Stake? Welding poses a unique combination of both safety and health risks to more than 500,000 workers in a wide variety of industries. The risk from fatal injuries alone is more than four deaths per thousand workers over a working lifetime. What’s the Danger? The fume plume is the clearly visible column of fume that rises directly from the spot of welding or cutting. ...

TVOC Monitoring
Total Volatile Organic Compounds (TVOC) are a group of compounds containing carbon that have a high vapor pressure present in the air. There are abundant VOC emitted from everyday activities among which some are colourless and some odourless and some are toxic. Therefore, TVOC monitoring is an efficient way to detect exposure to toxic VOCs. This article covers information on total volatile ...
