Load the last determination in the sample series that you have

previously saved (see Section 3.18.6). The method used and the

current statistics data will also be loaded together with the

determination. The statistics button under Control and the statistics

counter will have the same status as they had before the

interruption to the sample series.

Continue with the processing of the sample series.

You can view the statistics overview under Results/Statistics (see

Section 3.21). With [Delete statistics] you can delete the statistics

data manually.
The statistics data is deleted automatically in following cases:
• when the actual statistics counter (number of processed samples)

is the same as the preset number of determinations used for the

statistics. The maximum value of the statistics counter is defined

under Sequence/Method options.

• when a method is loaded with [Load method]. It does not matter

whether this is the same method that was previously loaded. If you

use either the sample data silo or the sample assignment table then

a check will be made whether the method is the same (file name is

the same) as that already loaded. Only when this is a different

method will the new method be loaded and the statistics deleted.

• when a determination is loaded. At the same time the method with

which the statistics have been calculated is also loaded.

3.17.2 Sample data silo

Under Control you can switch on the use of the sample data silo. The

sample data silo is a table in which the sample data for a sample

series can be entered and stored. If you have activated the Sample

data silo checkbox then at each START of a determination the

sample data will be taken from the silo memory. You can then open the

sample data table in the main dialog with [Sample data silo]. The

input of the sample data is described in Section 3.19.3.
With [Delete silo] (Touch Control only) you can delete all the lines in

the current silo. The settings made under Sample data

silo/Properties are retained.
