| |
| Single wavelength measurements are: | |
| Absorbance measurements: The light absorbed by the sample is measured in absorbance | |
| units. | |
Single Wavelength | Transmittance measurements (%): The percentage of the light that passes through the sample | |
| and reaches the detector is measured. | |
| Concentration measurements: A concentration factor can be entered to enable the measured | |
| absorbance values to be converted into concentration values. | |
| In the | |
Multi Wavelength | at up to four wavelengths and absorbance differences and absorbance relationships are | |
| calculated. Simple conversions into concentrations can also be carried out. | |
|
| |
| A wavelength scan shows how the light from a sample is absorbed over a defined wavelength | |
Wavelength Scan | spectrum.This function can be used to determine the wavelength at which the maximum | |
absorbance value can be measured.The absorbance behavior is displayed graphically during the | ||
| ||
| scan. | |
|
| |
Time Course | The time scan records the absorbance or % transmittance at a wavelength over a defined time. | |
|
| |
System Checks | The system checks menu offers a number of options, including optical checks, output checks, | |
lamp history, instrument update, service time and instrument backup. | ||
