Reference materials (RMs) are the substance whose characteristics or values have been well-established and used to monitor analytical process quality control for. It is considered as a calibrator for operation capability of instruments, as well as accuracy and robustness of assays. With accumulation years of experiences in the area, iPhase Biosciences has developed a group of accredited RMs at the national level (GWE grade), including conjugated lead or combo metal elements in bovine blood, lead, cadmium or chromium in cosmetic matrix, and 25-hydroxy vitamin D₃ [25-(OH) D₃] or 25-hydroxy vitamin D₂ [25-(OH) D₂] in human serum.

Quality Control materials (QCMs) are substances prepared at several concentrations for in-house uses to evaluate the repeatability of analytical processes, assess the operation capability of analysts, and control the performance of laboratories. IPHASE has developed hundreds of QC products that are commonly used in the analytical fields related. All these products have been cross-evaluated by multi-instruments and multi-laboratories for testing of drugs, clinical samples, cosmetics, food, and health products. Meanwhile, we offer customized products upon request for specialized applications.
