Checking the photometric accuracy with certified reference materials

Photometric accuracy (absorbance) is measured by shining a light beam from the spectrophotometer through the inserted filter. An absorbance value (Abs) can be deduced from the light attenuation caused by the filter. The light attenuation produced by the filter gives the absorbance value (Abs). A reference material for checking the photometric accuracy ideally has wide flat scan lines.

Hellma Analytics offers the following reference materials to check the photometric accuracy of your spectrophotometer:

Helpful tool for monitoring mean and target values

Control charts, such as e.g. target value charts are used to graphically display measured values. The value specified in the Hellma Analytics calibration certificate is used as the target value. All measured values must be within the range of the measurement uncertainty, otherwise there is an out-of-control situation.
