Killing Result Channels - Malvern Mastersizer Series Getting Started

1
The data channels may be killed by either using the Setup-Analysis dialogue or
by adding kill cursors to the data graph, as shown below. Both of these methods
create a new result with the channels killed. Alternatively you can set the killed
channels during the inspect phase of the measurement, as shown in the section on
Measure-Inspect in the Software reference manual.

Killing result channels

If it is not possible to remove the effects of contaminants and bubbles by killing
data channels then the alternative is to kill the result channels. These
contaminants form extra modes or peaks in the result after the analysis. By killing
result channels the characteristics of the expected result distribution are isolated.
In a similar manner to killing data channels, only channels at either end of the size
range may be killed. Any number of channels may be killed as long as at least one
channel remains unmodified. Unlike killing data channels the killed result
channels are simply zeroed and the remaining distribution re-normalised.
An alternative use for the kill result facility is to isolate a mode of the distribution
so that the characteristics of that mode may be obtained separately from the
complete distribution. This is particularly important if you are also transforming
the result, where small modes, caused by errors, in the volume distribution are
magnified and can become dominant when transformed to a number distribution.
See 'Transforming Result Type' later in this chapter.
The result channels may be killed by either using the Setup - Result
Modifications dialogue or by adding kill result cursors to the result graph.
