Aztec 600 aluminium, ammonia, color, iron, manganese, phosphate
Single- and multi-stream colorimetric analyzers
Appendix A – Reagents
A.1 Reagent Solutions
Warning.

Ensure personal protective equipment (PPE) such as
gloves and eye protection are worn during any
maintenance and that any spillages are cleaned-up.

Observe all health and safety procedures for handling
chemicals.
A standard set of reagents for an Aztec 600 analyzer (except an
Aztec 600 color analyzer) comprises 3 reagents (5 l of each) and
a high calibration standard (2.5 l). The Aztec 600 color analyzer
does not use reagents for measurement; a high calibration
standard is used only for automatic calibration.
Because the usage of de-ionised water depends on the
measurement range (see Table A.1) this is supplied separately
and available in 10 or 25 l sizes.

A.1.1 Reagent Storage
Store reagents in their original packaging, in a cool, dry, well
ventilated environment.
Note.

Do not use reagents outside their shelf life.

The following reagents are sensitive to light and must
be stored in dark bottles:
– Ammonia – Reagents 2 and 3
– Low Range Manganese – Reagent 3
Contact with visible, ultraviolet or infrared radiation
shortens the shelf life of these reagents.
2 types of reagent bottle kit are available from ABB – see
Appendix F.3, page 96.
A.2 Reagent Consumption
The reagent usage depends on how many samples an hour are
measured.
Typically 0.75 ml of each reagent is used per determination.
