Iron LR with Liquid reagent

0.03 – 2.00 mg/l Fe
This test is suitable for determining total soluble iron. The sample
should be pre-filtered using a 0.45 µm membrane if total dissolved
iron is required. Particulate or suspended iron will otherwise add to
the result.
Fill a clean vial (24 mm Ø) with 10 ml of the prepared water sample
and perform zero calibration (see "Operation").
Fill the vial with drops of the same size by holding the bottle vertically
and squeeze slowly:
10 drops KS61 (Ferrozine / Thioglycolate)
Close the vial tightly with the cap and invert several times to mix the
contents.
Place the vial in the sample chamber making sure that the
are aligned.
Wait for a reaction period of 5 minutes (Note 1).
(Countdown can be activated, see page 43)
The method symbol flashes for approx. 3 seconds.
The result is shown in the display in mg/l Iron.
