The AOD 1 is used for oxidative decomposition of solid and liquid organic
and partially unorganic samples under pressure in a closed system
The system
consists of:
- AOD 1.1 Decomposition vessel
- C 48 Oxygen station
- AOD 1.2 External ignition unit
- AOD 1.11 Control standard (50 ml)
- Quantitative decomposition of all halogens, sulfur, as well as volatile
metals, e.g. As and Hg
- Absorption of the combustion products in an aqueous
medium
- Catalytic support of the oxidation process with auto-regenerating
catalytic insidewalls of the decomposition vessel
- Pressure vessel of
high-grade stainless steel
- Decomposition temperature up to 1200 °C
-
Max. operating pressure during decomposition 195 bar
- Decomposition time
< 3 min
- The decomposition vessel can be changed over to use combustible
crucibles C 14
- Control standards for Cl, S ( AOD 1.11) , F and Br ( AOD
1.12 accessory )
- Introduction of the combustion gases into the absorption
solution via venting station C 7030
The principal and function is based on the method of the combustion in the
bomb calorimeter and validated according
DIN 51577, part 1 dt. 1982
other relevants validations are:
- DIN / EN 14582, determination
characteristics of waste, halogene and sulfur content
- DIN 51527 , Testing
of solid samples, determination for the clorine content
