Reagents and chemistry used with SEIBOLD COMPOSER Analysers are free from toxic compounds. Our "Green Thumb" project started in 2006 and delivered its first products in 2008. In 2011 the complete range of SEIBOLD COMPOSER Analyser for Heavy Metals has been introduced to the market.

SEIBOLD's Analyser series COMPOSER is based on spectrophotometric technology.
Measured concentration is a function of colour, formed by a complex of metal and reagents (buffer and dye). Photometric laboratory standard methods for heavy metal analysis are based on toxic and hazardous chemicals.

Many of our clients in drinking water plants state the strong obligation for non toxic reagents to reduce risk of operation and production.
The global trend towards green products for environmental care additionaly supports this initiative.
In 2006 SEIBOLD started investigation and development of new reagents for Iron and Manganese analysis.
After many tests and trials the reagent development is completed for the following heavy metals:

• Arsenic (As)
• Iron (Fe2+/3+) and total Iron
• Manganese (Mn)
• Chromate (Cr6+)
• Copper (Cu)
• Cadmium (Cd)
• Lead (Pb)
• Nickel (Ni)
• Zinc (Zn)

Non toxic reagents and real online analysis and robustness are our three basic design criteria.
These design criteria are responsible for low total cost of measurement (TCM).
Costs for shipping, handling and wasting of non toxic liquids are reduced.

Fortunately this reagent set is available also for other vendor's analysers. Please ask if your vendor of choice is supported.
