•
Method: UV-Vis spectrometry; use of the complete absorbance spectrum
•
Multiple measurements NO3 + TOC + DOC + Turbidity and more
•
Factory-calibrated
•
100% drift-compensated (*full* 2-beam-design)
•
Thus extremely long term stable
•
No replacement parts
•
Self cleaning, integrated into compressed air system
•
Intelligent, many self-diagnosis options
•
UV-spectrum can be used to alarm on suspect composition of the water (today’s standard for contamination alarm systems in USA)

“Calibration”
should read Parameterization:•
Not done in classical sense to tune in instrument. Rather•
Thousands of spectra from similar sources analysed and typical parameters built into “Global KALIB”
file. Can be the source of some confusion since it is not classical calibration.
Local “Calibration”•
If results don’t match lab’s results accurately enough, “Local Calibration”
is necessary
•
Samples are taken and correlated with Spectra, and Lab results are fed back to instrument
•
Calibration automatic standard or manual
•
Kalib
is only as good as reference measurement protocols
•
Multi-point-calibrations possible (spectro::lyser
model only)

Advanced “Calibration”
•
for “difficult”
or unique water matrix•
Fast changing / Variable composition of water•
for non-standardized applications and/or new parameters (in case no suitable “Global Calibration”
is available) •
individual service by s::can
partner to develop new spectral algorithm for individual water qualities or individual Parameters
•
s::can
software tools or traditional Chemometric
tools (PCA & PLS) as well as ana::larm
and contami::spec
can be used
•
opens unlimited applications in UV/VIS spectrometry
