SP600 Spectrophotometer 01/2008
1.1 Methods
Chromium, total (Cr(lll) + Cr(Vl))
with Powder Pack
0.2 – 2 mg/l Cr
Digestion:
1. Fill a clean vial (16 mm Ø) with
10 ml of the water sam-
ple
.
2. Add
one PERSULF.RGT FOR CR powder pack
straight
from the foil into the vial.
3. Close the vial tightly with the cap and swirl several
times to mix the contents.
4. Heat the vial for
120 minutes
in a preheated thermo-
reactor at a temperature of
100°C
.
5. Remove the vial from the thermoreactor.
(CAUTION: The vials are hot!).
Invert the vial and allow to cool to room temperature.
Performing test procedure:
6. Place the pre prepared vial in the sample chamber ma-
king sure that the marks are aligned.
7. Press
ZERO
key.
8. Remove the vial from the sample chamber.
9. Add
one CHROMIUM HEXAVALENT powder pack
straight from the foil to the water sample.
10. Close the vial tightly with the cap and swirl several
times to mix the contents.
11. Place the vial in the sample chamber making sure that
the marks are aligned.
12. Press
TEST
key.
Wait for a
reaction period of 5 minutes
.
After the reaction period is finished the measurement
starts automatically.
The result is shown in the display in mg/l total
Chromium.
