MQuant® Colorimetric and Titrimetric Test Systems for Various Testing Scenarios

color disk comparator

Color-disk Comparator
 
• High to medium concentrations
  as well as turbid solutions.
• All reagents and the color
  comparator disk are contained
  in the kit.
• These tests evaluate the color
  reaction based on the transmitted
  light method, so even turbid and
  lightly colored water samples
  can be analyzed without further
  preparation.

Application areas:
• Wastewater
• Industrial water
• Groundwater
• Bottled water
• Boiler water
• Swimming pool water
• Industrial applications








titrimetric and colorimetric methods

Titrimetric and Colorimetric Methods
• Medium concentrations can be
  measured by titrimetric or
  colorimetric tests.
  Evaluation using color cards
  or test vessels.

Titrimetric test:
• The sample is titrated until
  its color changes. The number
  of drops consumed to the turning
  point are counted, or the scale
  value is read from a pipette to
  determine the concentration of
  the tested parameter.

Colorimetric test:
• Reagents are added to the sample,
  resulting in a color reaction.
• The concentration is determined by
  matching the color to a value on a
  reference scale.

Application areas:
• Aquaculture for freshwater and
  seawater
• Surface water
• Swimming pool water
• School lessons

color-card comparator

Color-card Comparator
 
• Very low to medium
  concentrations.
• The c greater layer thickness and
  special construction of the
  comparator ensure high
  measurement sensitivity, even at
  very low concentrations
  (ppb range).
• The reaction color of the sample is
  compared to the blank sample
  tinted by the color cards to
  determine the concentration.
  The brilliant print and fine
  color graduation enable precise
  analyses.

Application areas:
• Drinking water
• Bottled water
• Boiler water
• Cooling water
• Industrial applications
