SECTION 6 – Concentration

The concentration measurement mode enables simple measurements of absorbance and concentration

to be performed. In this measurement mode it is possible to calibrate against a standard of a known

concentration or use a known factor. The sample is measured at one wavelength at one point in time.

There are no post measurement calculations available in this measurement mode.

6.1 MODE SPECIFIC PARAMETERS

The concentration operating menu enables measurement

parameters to be changed. The utility toolbar on the left

hand side of the screen enables access to printing, print

setup options, results, methods and autologging options.

For more details on the different functions of the utility

toolbar refer to section 17. The settings icon enables the

wavelength, units, resolution, standard or factor to be

set.
