5.12.4.1 Reference- Parameters
Name of file: here is reported the name used to save the reference file
Reference: Reference samples are reported in this graph for monitoring the
trend in the time
Reference table: list of reference samples reported automatically from the
Measure page once analyzed.
Number of reference sample: The reference samples are put in order of
execution
Date: execution date and time of reference sample
Ng values: Values in “ng” (absolute value of Hg) of the reference sample
Cal-Factor: value calculated by the “theoretical value” divided by “measured
value” of reference sample
Summation: clicking in this field, the line is selected, and the sample will be
included in the statistic calculations. The sum icon can be removed at any time
by clicking on again.
Cal. File: here the calibration curve to the which the reference sample is
calculated is reported
Remarks: here operator comments are entered
σ: If more reference samples are selected, here the standard deviation is
calculated
m: here the average of Cal- Factor values is calculated. If only one reference
sample is selected, then here the value is reported. If no reference samples are
selected, the “m” value for Cal- Factor will be automatically set to “1.0000”
Standard Cal- Factor: Clicking on the arrow, the “m” value calculated after
selecting reference samples will be reported as standard Cal- Factor and
automatically set in the “Cal-Factor” columns when you start a new
measurement line in Measure page
5.12.4.2 Reference measurements
The calibration curve can be corrected with a calibration factor lower or higher than “1.0000”. Measure a
reference sample with known Hg content, in order to keep the calibration under control.
