Observations

It is recommended to add the sample and reagents with the glass

tube inside the rack to avoid spill liquids inside the instrument.

The tube must be before each analysis.

after having added the Acid reagent.

It is important not to touch the tube once it is inserted inside the

instrument as glass walls from the tube are not completely regular

so a turn or movement will alter the detection of light beam.
