Oxygen Test Preparation
Prepare the test solution by mixing one
volume of Sp. Gr.0.90 Ammonium Hydroxide (NH4OH) with two volumes of
distilled water and add Ammonium Chloride until solid crystals remain
undisclosed at the bottom of the container.
Invert the reaction chamber set, remove the rubber cork 'F' and fill the
reaction chamber 'D' with copper wire in spiral form replace the bung and
return it in an upright position and connect with the burette tubing. Fill
the reservoir and reaction chamber three quarter with fresh test solution
with the leveling bottle 'B' held below the level of the burette, half fill
the bottle with the test solution.
Draw the test solution from the reservoir in the reaction chamber by
turning the burette stop cock 'H' to connect the burette with the reaction
chamber and then lowering the leveling bottle. Squeeze the rubber pipe to
expel all the air and then close the stop cock, so that reaction chamber and
the inter-connecting rubber pipe are completely filled with test solution.
The purging vessel (lute) is half filled with water and the sample gas to
be tested is allowed to bubble through water to atmosphere. Fill the burette
with fresh solution by turning the stop cocks 'G' and 'H' to connect with
the purging vessel, so that , all the air gets expelled. Repeat it till all
the air bubbles are removed. When solution commences to flow from the
burette to glass tube, close the stop cock 'G' close the cock it and replace
the leveling bottle in the holder.
