Chengfenbao Testing is an analytical laboratory in Hangzhou, China. We deformulate industrial products and raw materials for manufacturers outside China, including inks, coatings, adhesives, sealants, rubber and plastic compounds, process additives, cleaners, lubricating greases, and plant-derived food ingredients. We identify main components, estimate their proportions, state uncertainties, and issue an English PDF report. Overseas samples are reviewed before shipment; do not ship until we issue an acceptance number.
Deformulation rarely yields to a single instrument, so we combine several techniques on the same sample, including LC-MS/MS, GC-MS and ICP-MS. Our analysts choose the methods for each sample and interpret the data.
