Note: Before using the test with your photometer for the first time, determine the reagent blank
value.
YSI model no.: Mo-2 TP
Category: RT (reagent test)
Cell: 28 mm
Measuring range: 0.3 - 40.0 mg/l Mo
Display in mmol/l possible
Check the pH value of
the sample.
Nominal value: approx.
pH 7.
Correct with diluted
sodium hydroxide
solution or nitric acid as
necessary. Pipette 25.0 ml of
sample into an empty
beaker. Add the contents of a
Vario Molybdenum
HR 1 F25 ml powder
pack and dissolve them
by stirring. Add the contents of a
Vario Molybdenum
HR 2 F25 ml powder
pack and dissolve them
by stirring. Add the contents of a
Vario Molybdenum
HR 3 F25 ml powder
pack and dissolve them
by stirring.
Allow to react for 5
minutes. Fill an empty cell with the
prepared sample and
close it with the screw
cap. Insert the cell in the
photometer cell shaft
and start measurement.
Notes:
• We recommend to determine a new reagent blank value (deionized water instead of sample) for each test package started.
• If any molybdenum is present, the solution develops a yellow color after all reagents have been added.
