Note: Before using the test with your photometer for the first time, determine the reagent blank
value.
YSI model no.: Fe-2 TP
Category: RT (reagent test)
Cell: 28 mm
Measuring range: 0.02 - 3.00 mg/l Fe
Display in mmol/l possible
Check the pH value of
the sample.
Desired range: pH 3-5.
Correct with diluted
sodium hydroxide
solution or hydrochloric
acid as necessary. Pipette 10.0 ml of sample
into the empty cell. Add the contents of a
VARIO Ferro F10
powder pack and close
the cell with the screw
cap. Mix the contents by
carefully swaying the cell
(10 x).
Undissolved powder has
no adverse effect on
measurement. Allow to react for 3
minutes (reaction time).
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.
• This method covers all forms of dissolved iron and most forms of undissolved iron.
• In the case of samples with visible rust the reaction time should be extended to at least 5 minutes.
