4.2 Sampling Requirements

Selection of a good, representative sampling point is critical to
obtain optimum performance from the analyzer.
To reduce sample dead time, locate the analyzer as close to the
sampling point as possible.
Use small diameter tubing for sampling lines to minimize the lag
time but large enough not to block.
The sample must also conform to the following conditions:

Sample flow rates must be greater than 200 ml/min and
less than 500 ml/min.

Sample temperature must be within the range 1 to 40 °C
(32 to 104 °F).

Samples must not
100 microns in size. Above these levels, an external filter
must be fitted to the sample lines.

Sample must be at atmospheric pressure. It must be as
close to the analyzer as possible and the sampling point
must provide a thoroughly mixed representative sample.

4.3 Location

For general location requirements refer to Fig. 4.1. Install in a
clean, dry, well ventilated and vibration-free location giving easy
access and where short sample lines can be used. Avoid rooms
containing corrosive gases or vapors, for example, chlorination
equipment or chlorine gas cylinders.
It is also advisable to have adjacent drains near ground level, so
that the waste outlet from the analyzer can be as short as
possible, together with maximum fall.
If a reagent tray is used, it must be mounted directly below the
bottom plate of the analyzer housing – see Section 4.5,
page 14.
The power supply and power isolation switch must be adjacent
to the analyzer.
