Each week brings a new report of problems with toy safety and consumer product safety. Ultimately, contract manufacturers, importers, distributors, retailers and brand owners all face potential liability when they fail to comply with laws which restrict the levels of toxic materials in their products. Handheld Niton analysers provide quick and easy screening of toys and other consumer goods for lead, cadmium, mercury and other toxic metals. Importers, brand owners and retailers can implement a standardised inspection protocol for incoming shipments to verify compliance, while simultaneously requiring supply chain documentation based on empirical testing.
Fungicide carbendazim can some times be used to combat mold on citrus fruits including oranges. Recently, low residue levels of the fungicide were reported to be present in the bulk orange juice import shipments to the USA. Because this compound can persist through processing steps and may be found in the final consumer product, many government agencies have established maximum residue limits (MRLs) to ensure the safety of their population.
Presented here is a single method, involving fast and effective QuEChERS cleanup, suitable for various orange juice matrices. The choice of PSA/C18 sorbents reduced interferences, resulting in greater recoveries and less ion-suppression. Because the QuEChERS method is fast, it only adds a few minutes to the
sample preparation procedure. Sample processing using QuEChERS with PSA/C18 allows analysts to accurately process various matrices in a single workflow, with very little additional sample preparation time.
Compliance screening and testing is often carried out during the manufacturing phase of a product, and all the way through its disposal or recycling process. It ensures that products and materials meet specific standards or comply with international and local directives or regulations. These standards and regulations are introduced to ensure the quality and safety of a product, and to minimise or eliminate its negative impact on the environment and people. Examples of products or materials tested are: electrical and electronic equipment (for compliance with the Restriction of Hazardous Substances (RoHS) directive), waste oils, soil (soil remediation depending on contents of toxic metals), children’s products (for compliance with Consumer Product Safety Improvement Act of 2008), etc.
The use of polymeric polyols is commonplace in the manufacturing of polyurethanes and other specialty polymers. The hydroxyl number (OH#) is a measure of the concentration of the hydroxyl groups on the polyol. This is an important parameter to monitor and control during polyol production. The laboratory method that is commonplace for hydroxyl number determination is both time consuming and involves the use of hazardous materials. This note will discuss the use of Guided Wave hardware and software tools for the measurement of hydroxyl number in polyols using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time directly in process or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods. NIR also offers the benefit of increased safety over traditional methods. For well established process measurements, a Guided Wave ClearView® db multi-wavelength photometer can be used to achieve similar results.
