Modifying results

The result produced by the analysis may be modified in a number of ways before
it is presented in the graph or table.
The modifications are controlled from the Setup-Result Modifications
dialogue. In this dialogue you have the option of setting the modifications so they
are applied to the current result only, or to the subsequent measurement results.
The modification setup is saved with each result record and can be loaded for
alteration.
The modifications to the standard result are:
Blend Results - two results of the same sample measured with different
range lenses can be blended to produce a result across two size ranges.
Shape Correction - the Mastersizer size range can be modified to make
the result comparable with that from other sizing methods.
Extend Result - results from other sizing methods can be added to the
Mastersizer result to extend the result range.
Transform Result - the default volume distribution result is transformed
to surface area, length or number distributions.
Kill Result - one or more result channels can be removed to isolate a result
or remove the effects of noise.
Kill Data - One or more data channels can be removed from the analysis,
limiting the effects of bubbles and other contaminants, such as propellant
gasses during spray measurements. This modification is carried out as part
of the result calculation.
Each of these modifications will now be discussed in detail.

Killing channels

Killing data channels

The analysis normally uses all the data channels.
of measurement in which it is inherently impossible to obtain all channels
measured accurately.
kill data ranges to exclude a few channels at the lower or upper end of the range.
These channels are removed from the analysis by setting the

There are, however, some types
