EA-IRMS for solid
and liquid samples. In year 2000, Mindex introduced a dedicated line of
Elemental Analyzers (EA) and Pyrolytic Unit (PyrOH) to be couple with IRMS.
Since then EA have been regarded as innovation leader in Continuous
Flow-EA-IRMS. In consideration of the expansion of the segment and new emerging
requirements, Mindex Ltd have incorporated year after year a number of
accessories, in line with the stringent requirements for this technique.
Present offering of products and related applications are: EA3024-IRMS (up to
1100°C) for (NC), (S), in combustion - (H) in water Pyrolysis
EA3028-IRMS (up to 1200°C) for (NC), (S), in combustion - (H) (O)
in water Pyrolysis SATELLITE Unit Incorporating HT-Furnace for (O-H) Pyrolysis
up to 1500°C |

| Combustion systems
are working at Low Temperature (LT) at around 1000°C. They guarantee high
throughput for (NC), 500 Analyses, and (S), 400 Analyses, without user
intervention. (H) & (O) Pyrolysis in water analysis are performed at
1050°C or 1150°C using Modified Quartz reactor. For (H-O) Pyrolysis in
Organic and Inorganic solid samples, HT-Furnaces up to 1500°C and
Ceramic-Glassy Carbon Reactors are needed. The features of the Satellite Unit,
as add-on to EA to perform HT Pyrolytic Application preserving Combustion
applications layout, are reported here below. |

In the combined
technique of Catalytic Pyrolysis (PyrOH) coupled with (IRMS), the overall
system accuracy is mainly due to the PyrOH ability to face issues related to
the critical steps of Organic and Inorganic solid samples conversion into gas
species. PyrOH performing to expectation in providing CO and H2 representative
gases is the today challenge to achieve improved overall results.

The hearth of the
system is the innovative neat approach of the HT-Furnace built-in in the
purposely designed Satellite Unit featuring multilevel temperature set,
programmable heating rate, adjustable thermocouple, electronic control of
direct radiation heat transfer and effective cooling system. Thanks to the new
design approach a constant temperature profile is obtained in the entire hot
zone and IRMS background is reduced. The novel catalyst avoiding gas adsorption
effects, contribution of the VectorSAS True Zero Blank AutoSampler keeping
contamination for (O) at nanogram level and care to implement several specific
details required in the analytical layout to protect the hot gas mixture
integrity are additional key factors allowing consistent d per/mil improved
results in the combined PyrOH-IRMS Systems. |
