Restrictions for use
Alcalizing
Reagent
Correct the pH of the sample with Diisopropylamine only, however,
Diisopropylamine is not included in delivery. Please buy it from your
local supplier: E.g. VWR 6x 1l: 8.03646.1000, or SIGMA 38290-1L-F.
Sample
Require-
ments
No sand (or other polishing material) or oil are allowed in the sam-
ple.
The instrument is specified for a max. pressure of 2 bar (28 psi). If
the sample pressure exceeds 2 bar, please mount a pressure re-
duction in front of the instrument inlet.
Phosphates may interfere with the hydrazine measurement.
The pH value of the sample must be equal or higher than pH 7.
Flow
Interruption
High concentrations of Diisopropylamine reagent may attack the
acrylic material of the flow cell. This can cause cracks and render
the flow cell completely unusable. This will not happen during nor-
mal operation. However, if the sample flow is stopped, undiluted di-
isoproylamine will diffuse through the diffusion tube and can cause
damage. Therefore, the following rules should be observed if the
sample flow is stopped for more than one day:
Remove diisopropylamine bottle and close it. Keep it in a safe
place for further use.
WARNING
Diisopropylamine is corrosive.
Read the Safety Data Sheets (SDS) first.
Wear suitable protective clothing, gloves and eye/face protec-
tion.
Avoid inhalation of DIPA vapor.
In case of contact with eyes, rinse immediately with plenty of
water eyelid wide open for at least 10 min, summon medical
advice. In case of accident or if you feel unwell, summon
medical advice immediately (show the label where possible).
Screw an empty reagent bottle on the holder.
Let the sample flow for another 30 minutes to rinse out the Di-
isopropylamine dissolved in the diffusion tubing material.
Stop sample flow.
