6.7 Time course of absorbance/transmittance

The Time Course Mode is used to collect data in either absorbance

or transmittance for a user-specified length of time. After the data

are collected, they can be displayed in either graphic or tabular

format.

6.7.1 Time course setup parameters

Press Time Course mode in the Main Menu. Press Options to

configure parameters.

Option Description

More For further Options

Store icon To store the scan data

Time & Interval To input the total time for data collection and the time interval between the collection of data

points

λ To input the wavelength setting

View Table/Graph To display readings in absorbance, transmittance or concentration. This can be changed after

sample data are collected

Scale & Units

Scale: In the automatic scaling mode, the y-axis is automatically adjusted so that the total scan is

displayed.

The manual scaling mode allows sections of the scan to be displayed.

Units: Choice of absorbance or transmittance.
