For an introduction to the application and use of Certified Reference Materials in absorption spectrophotometry

These cell-based reference materials are designed for the qualification of HPLC UV detectors that can accept conventional spectrophotometer cells, e.g. Waters.


Erbium Oxide Solution – Wavelength Qualification

9 well defined peaks from 230 nm to 660 nm. For HPLC UV detectors that can accept conventional spectrophotometer cells, e.g. Waters.


Propyl Parabenz Solution – Photometric Linearity Qualification

Five concentrations (5 mg/l - 30 mg/l) of  Propyl Parabenz in methanol  . For HPLC UV detectors that can accept conventional spectrophotometer cells, e.g. Waters.
