Mathematics overview

Very often, analytical data must be transformed, units must be converted or data must be scaled to meet the user requirements or for comparison with other data. All these required manipulation operations will be provided by the mathematics module of the software. Mathematical methods can be applied to analytical data subsequently to yield the results, the user likes to see.

Thus basic mathematical methods of the software are used to manipulate spectral data either temporarily or permanently. All manipulations will be logged in the audit trail of the manipulated object for CFR 21 part 11 compliance. This way, changes can be tracked easily. Some of the mathematical methods are data type dependent and others are available with all data types.

In case the selected operation is not valid for the current data type, the user will be prompted.

In general, equidistant and discrete data objects will be distinguished. This is necessary since not all operations can be carried out with discrete objects. A typical example for a discrete object is a mass spectrum, which contains a lot of non-equidistant data points. For example the Adjust x-Axis method will not work with such data.

Applicable mathematical functions.

Some of the mathematical functions can only be applied to a particular data type. In this case, the mathematical function is missing or disabled.
