Installation of DIPA Reagent and Diffusion
Tubing
WARNING: The diisopropylamine (DIPA) reagent is hazardous. Use protective glasses and
gloves. Refer to the bottle label for precautions and work in a well-ventilated area. Installation of
DIPA reagent requires a fume hood or well-ventilated area.
Recommendations
If the analyzer is offline or the sample flow is shut off from the analyzer for a prolonged period of
time, follow the steps in Section 3, Shutdown and Start-Up Procedure.
1. Unscrew the thumb nut and remove the reagent bottle from the reagent manifold.
New analyzers will ship with a rubber coated glass reagent bottle and complete diffusion

tubing assembly installed. Only installation of the reagent is necessary for first time
start-up.
2. Twist open the reagent bottle, separating the glass bottle, reagent bottle adapter assembly
and plastic cap to the reagent bottle.
DIPA Diffusion Tubing Assembly
Designed to maximize uptime, our new diffusion tubing assembly can be replaced in a matter of
seconds. Our method of snap and connect tubing installation combined with the easy pull off
and dispose technique will have your system back online faster than ever before. The newly
designed mechanism is precisely engineered to remain connected under variable temperature
conditions and pressure fluctuations. The new style diffusion tubing assembly is now suspended
in the headspace of the reagent bottle, which decreases the rate of consumption of reagent and
saves you time and money.
The diffusion tubing ships fully assembled for quick and easy installation.
Do not use Teflon tape during installation.

Twisting of the clear silicone tubing will compromise tubing integrity and may cause

ruptures. Be careful to avoid kinks and twisting during installation.
