Summand / Factor
Summand
allows to define the linear increase in the spacing between data points if
linear
was chosen
in
Shape
.
Factor
allows to define the exponential increase in the spacing between data points if
exp
was chosen in
Shape
. For
const
this option is disabled. Select a Summand / Factor by choosing an
appropriate one from the drop down menu. Note that only predefined values are available.
If the kinetic will last for longer than one day, a
warning is displayed (Fig. 42). Click

Let's define the following variables:
Time delay between consecutive data points = pi
(given start value=p0)
Start time of the measurement: pt,i
Number of data points: n
Data point counts = i (note: i starts with 0; so for
the first data point i = 0; or general i = n-1)
Summand/Factor = f
In
const
(constant) the period between two successive data points is constant and will be exactly the time
selected in the
Point to Point time
selection box.

In
lin
the period between two successive data points as specified in the
Point to Point time
selection
box is increased linearly by a summand of which the initial value is defined in the
Summand
selection
box.

In
exp
the period between two successive measuring cycles as specified in the
Point to Point time
selection box is increased by an exponential factor of which the initial base is defined in the
Factor
selection box. Note, that the first measurement is therefore assigned a 0 for the exponent.

Procedure to set up a kinetics
•
Enter the time spacing you want to start with in the
Point to Point time
input box of your kinetics
measurement.
•
Enter the number of data points in the
Number
box. Remember that the first data point is counted as
"0".
•
In the
Shape
selection box, set one of the shape options
const
,
lin
or
exp
.
•
Enter a number in the
Summand / Factor
selection box.
•
Leave the Use Kinetics check box ticked.
