In manufacturing there are five main factors that have a direct impact on product quality: product design, incoming raw materials, processing, storage and transportation. Of these, incoming raw materials can account for up to 50% of the problems. Incoming raw material quality control (IQC) is therefore a key quality control step before the manufacturing process. If a substandard or incorrect raw material is used in the manufacturing process it may lead to failure of the process or final product, potentially resulting in substantial monetary losses. Thus the IQC affects not only the quality of final product but also various direct and indirect costs of production and, therefore, the profitability of the product.
Near infrared spectroscopy (NIR) is widely used in industries such as chemical, pharmaceutical, nutraceutical, dietary supplement, food, and others, for rapid, non-destructive, in-situ raw material inspections. Near-infrared spectra are the result of the absorption of light by combination and overtone bands of C-H, N-H, and O-H molecular groups, and can be used for identification and quantitative analysis of most organic compounds. Incoming raw materials can even be measured in their container, through plastic bag, within seconds.
Galaxy Scientific offers rugged, high performance, portable FT-NIR instruments that are suitable for raw material inspection in the warehouse or loading dock.
