Fig. 24 Window CALIBRATION - DATA OF NEW CALIBRATION
Result table The following are displayed:
number of detections
target concentration used for constant sample volume
sample volume used for constant concentration
average value of the area integers
average values of the calculated concentrations
percentage deviation of the calculated concentration and the
target concentration
Linear regression/
Quadratic regression
Dependent on the methodology selected the regression calculation
and determination of the method characteristics is based on
individual values or average values of the net integer. For the
selected regression type the respective calibration coefficients are
displayed.
Calibration graph The regression graph can be displayed for the program-internal
calibration coefficient determination (x axis - integer, y axis-
mass) or for the determination of the method characteristics (x
axis - mass; y axis - integer). The view can be switched in the V
IEW
▸ CALIBRATION GRAPH menu.
Method characteristics Verification/detection and determination limit:
In multiWin the calculation rules of DIN 32645 (calibration
function) are used with a significance level of P = 95 %.
For the calculation of the determination limit a relative result
uncertainty of 33.3 % is being assumed (factor k = 3). Other
method characteristics see also section "Method characteristics"
p.37.
