REACH Substance Identification Testing

Under REACH, there is a requirement to identify and name not only substances of well-defined qualitative and quantitative composition, but also those that are of Unknown or Variable composition, Complex reaction products or Biological materials (UVCB substances). Further, it is a requirement that registrants provide adequate spectral data to confirm the structure of their substance and also verify its composition and purity through the use of suitable chromatographic methods.
