Case Study:
Contaminant Identified 
A manufacturer faced downtime due to contamination in a liquid used in semiconductor production. Needing quick and accurate answers, they called Chemir. The sample was lyophilized and analyzed by Nuclear Magnetic Resonance Spectroscopy (NMR). The analysis revealed the presence of poly-N-methyl-4-vinylpyridinium methylsulfate, a type of polymer. This contaminant was then confirmed by Fourier Transform Infrared Spectroscopy (FTIR) analysis. The client was able to identify the source of contamination, prevent further contamination, and avoid production downtime.
