Wait time (sec.):
measure time of D1 phase (see § 3.2.3)
Lag Time (sec.): this field is only used for execution of KINETICS and FIXED TIME.
(see. § 3.3.3-3.3.4).
¾
Offset parameters
panel:
The Offset value is automatically set during the
Blank measure
.
The value must be within the range defined by
Minimum offset
and
Maximum offset
and
it
can be a positive or negative number depending on the method.
During Blank measurement:
If the Offset value stays within Minimum offset and Maximum offset range
,
the result on the screen will be displayed in
green
.
This result is saved in the method settings, in the
Offset
field.
If the Offset value is not within Minimum offset and Maximum offset range
,
the result on the screen will be displayed in
red
.
This result is not saved in the method settings.
¾
Slope
parameters
panel
The Slope value is automatically set during the
Calibrate measure
.
The value must be within the range defined by
Minimum slope
and
Maximum
slope
and
it can
be a positive or negative number depending on the method.
During Calibration measurement:
If the Slope value stays within Minimum slope and Maximum slope,
the result on the screen will be displayed in
green
.
This result is saved in the method settings, in the
Slope
field .
If the Slope value is not within Minimum slope and Maximum slope,
the result on the screen will be displayed in
red
.
This result is not saved in the method settings.
Significance of slope parameter:
The slope corresponds to the gradient of calibration linear regression of the method.
It is defined during calibration procedure, according to the following equation:
Slope= Calibrator concentration / Calibrator Signal
The slope is then used by the program itself during samples analysis, according to the
following equation, to relate sample signal to its concentration:
Sample concentration = Slope x Sample signal
