Transmittance reading (%): Measures the percent of the original light that passes through the
sample and reaches the detector. Concentration readings: A concentration factor can be entered to enable the measured
absorbance values to be converted into concentration values. In the Multi Wavelength mode, absorbance (Abs) or percentage transmittance (%T) is
measured 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 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.
The time scan records the absorbance or % transmittance at a wavelength over a defined time.
The "System check" menu offers a number of options, including optical checks, output checks, lamp history, instrument update, service time, settings for analytical quality assurance and instrument backup.
In this mode, user-specific or method-specific settings can be entered: operator ID, sample ID, date & time, sound, PC & printer, password, energy-saving mode and stored data.
