Programs
(HACH-LANGE
programs)
Stored programs are pre-programmed methods that make
use of HACH chemicals and HACH-LANGE pipette tests.
The working procedures for HACH-LANGE tests are
included in the test packs.
Further information, as well as illustrated, step-by-step
process instructions for analyses using HACH programs, are
available on the website of the manufacturer.
User Programs
User programs make "made to measure analysis" possible:
• Users can program methods they have
developed themselves
• Existing HACH- and HACH-LANGE procedures
can be stored as user programs. These
procedures can then be modified according to
separate requirements.

requirements.
Single
Wavelength
Single wavelength readings are:
Absorbance readings: The light absorbed by the sample is
measured in absorbance units.
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.
Multi
Wavelength
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.
Wavelength
Scan
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.
Time course
The time scan records the absorbance or % transmittance at
a wavelength over a defined time.
System checks
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.
