Pipette 0.50 ml of Pb-1
into a test tube.
Add 0.50 ml of Pb-2
with pipette and mix.
Measuring 0.10 – 5.00 mg/l Pb 10-mm cell
range: 0.05 – 2.50 mg/l Pb 20-mm cell
0.010 –1.000 mg/l Pb 50-mm cell
Expression of results also possible in mmol/l.
Lead

Test
Transfer the solution into
a corresponding cell.
Select method with
AutoSelector.
Place the cell into the
cell compartment.
Add 8.0 ml of the
sample with pipette and
mix.
Quality assurance:
To check the measurement system (test reagents,
measurement device, and handling) w
e recommended
to use Spectroquant
®
CombiCheck 40, Cat.No. 114692.
Ready-for-use lead standard solution Certipur
®
,
Cat.No. 119776, concentration 1000 mg/l Pb, can also
be used after diluting accordingly.
To check for sample-dependent effects the use of addition
solutions (e.g. in CombiCheck 40) is highly recommended.
Important:
For the determination of total lead a pretreatment
with Crack Set 10
C, Cat.No. 114688, or Crack Set 10,
Cat.No. 114687, and thermoreactor is necessary.
Result can be expressed as sum of lead ( Pb).
Check the pH of the
sample, specified range
:
pH 3 – 6.
If required, add dilute
ammonia solution or
nitric acid drop by drop
to adjust the pH.
