SECTION 8

– KINETICS

The kinetics measurement mode enables the absorbance or % transmittance of an active molecule to

be measured over a period of time; for example enzyme analysis of horseradish peroxidase. The

absorbance or % transmittance is measured at regular time intervals at a set wavelength over a

period of time. The results are plotted on a graph to show the change in absorbance or %

transmittance over time. Following sample measurement statistical analysis of all or part of the

experiment can be performed.

8.1

KINETICS MODE SCREEN

Operating Menu

The

kinetics

measurement

mode

enables

measurement parameters to be changed and post

measurement tools to be accessed. The four options at

the bottom of the screen allow the user to edit the

kinetics run settings, select the measurement mode,

perform a linear regression analysis on the data and

perform a post measurement search of the

scan’s data

points.

These

options

are

selected

with

the

corresponding function buttons.

8.2

WAVELENGTH SELECTION

The wavelength can be adjusted by pressing the GOTO

key on the instrument keypad. The required

wavelength can then be entered using the numerical keypad. Press the Enter key to confirm.

8.3

METHOD SETUP

The kinetics scan settings can be edited by pressing

the function key below the Setup option. The options

that can be changed are:-

1. Run Time

2. Delay Time

3. Time Interval

The numeric keypad should be used to enter the required run and delay times and the up and down

arrow keys are used to select from the available time interval options. Press the Enter key to confirm.
