who needs UncertaintyManager®?

UncertaintyManager® – rapid determination of measurement uncertainty of analytical results

UncertaintyManager® tells you the sources of uncertainty in your method

Knowledge of the uncertainty is a precondition for correctly assessing the results of any measurement.  Whether threshold values have been exceeded or whether a product meets its specifications can only be determined if the uncertainty of the measurement is taken into account.  UncertaintyManager® is therefore a very important tool for analytical laboratories working in the following and related areas:

input required for UncertaintyManager®

A range of templates, provided by UncertaintyManager®, can be used to define the analytical procedure:

  • equation
  • manufacturers and types of instruments used for the measurement
  • influences of sample preparation steps
  • a choice of types of calibration
  • several conditions under which the precision is
  • determined
  • recovery and standardized methodsback to the top

data required for the calculation

  • data from method validation
  • data from a typical measurement

depicted results

  • the overall measurement uncertainty for the analytical procedure
  • a histogram that shows the amount of individual uncertainty contributions
  • a diagram that shows the trend of measurement uncertainty over the whole working range of the analytical procedure
  • the distribution of the result calculated with Monte Carlo
  • a cause-and-effect diagram which shows all uncertainty influences and their relationships
  • 3 different report formats

outstanding features

  • time-saving
    using UncertaintyManager, the whole evaluation procedure of measurement uncertainty takes only a few minutes.
  • easy to handle
    • functional user guidance through the different steps of the evaluation procedure
    • the software offers different templates
    • by generating a flow-chart for the analytical procedure, all data needed are assembled from the extensive database of the system (instrumentation, reference substances, sample preparation)
  • two independent calculation methods
    • simulation using random numbers (Monte Carlo) takes into account correlations between the uncertainty sources.  Monte Carlo is the calculation method of the future.
    • uncertainty propagation (formal partial derivatives)
  • peak overlap
