Convert migration times to effective mobilitySource:
convertMtime performs effective mobility scale transformation of CE(-MS)
data, which is used to overcome variations of the migration times, caused by
differences in the Electroosmotic Flow (EOF) between different runs.
In order to monitor the EOF and perform the transformation, neutral or
charged EOF markers are spiked into the sample before analysis. The
information of the EOF markers (migration time and effective mobility) will
be then used to perform the effective mobility transformation of the
migration time scale.
numericvector with migration times in minutes.
numericvector that holds the migration times (in minutes) of either one or two EOF markers in the same run of which the migration time is going to be transformed.
numericvector containing the respective effective mobility (in in mm^2 / (kV * min)) of the EOF markers. If two markers are used, one is expected to be the neutral marker, i.e. having a mobility of 0.
numerica single value that defines the time (in minutes) of the electrical field ramp. The default is 0.
numerica single value that defines the voltage (in kV) applied. Note that for reversed polarity CE mode a negative value is needed. Is only used if the transformation is performed based on a single marker.
numerica single value that defines the total length (in mm) of the capillary that was used for CE(-MS) analysis. Is only used if the transformation is performed based on a single marker.
