Product Contamination Visualization and Identification Using

Sampling of Imperfections During Product ManufactureIdentification of Contaminants in Pharmaceutical ProductionConclusionImperfections during the manufacturing process can be costly, especially if the entire process has to be halted. SurveyIR can be implemented on the manufacturing floor to provide fast and reliable results. Depending on the size of the imperfections, they can be directly sampled via the clip-on ATR or removed and sampled on a reflective surface or an IR transparent window. Figure 4(left) shows a contaminant in oblique illumination that was observed in an engineered plastic molding and was excised for analysis. The excised particle was flattened and transferred to a KBr window to collect IR spectral information in transmission. Spectra on the right represent the excised contaminant (blue) and two components that showed strong correlation to the excised contaminant. The strongest correlation was that of silica gel (red), a common synthetic silicate. Ethoxylated tallow alkyl amine (purple) showed some similarity to the excised particle in Figure 4.
