Sample preparation for trace element analysis of seawater and sediment samples
Especially for the sample preparation for the trace element analysis of seawater and sediment samples, MK had built an entirely metal free laboratory with clean room condition for the Carl von Ossietzky University of Oldenburg. Now they can prepare supersensitive samples for the analysis of trace element and isotope concentrations, on which they can track deep water current in Oceans and their historical evolution. The characteristics of the metal free and therefor corrosion free clean room are diverse. The acidic vapors of highly concentrated acids which will occur on preparation of the sediment rock for the analysis don’t strain the materials of the workstations.

Laboratory system full of plastics
Based on task and process oriented laboratory design MK Metalfree Corp designed and manufactured the clean room and all the individual equipment. All materials for the work space, substructures, sub ceiling, interior wall and pipework are acid-proofed plastics as polypropylene, Teflon, PMMA or PET. The windows of the closed workstations were made of high-strength and transparent polyethylenterephthalat.
The total area comes to 55m². The air quality in the laboratory complies with class 6 of DIN EN ISO 14644, at the workstation the particle count complies with class 4 or 5. Sensors continuously monitor all control and measure devices at the workstations. Horizontal laminar air flow will prevent permanently the contamination of the sensitive work area by using the displacement principle. As well all supply lines of the air inclusive the filters and all other equipment’s for the air treatment were special components and made of plastics.
Energy and economic efficiency
The fast control flaps (designed and manufactured by MK) for the supply and extract air of the room and workstations allow a precisely accurate air control. This ensures an extremely high degree of safety and non-contamination. Hereby harmful particles can’t get out and dirt particles can’t get into the work area. Through an individual control of the room and workstations a night setback is possible. If the stations are not in use, the stations switch to a lowered ventilation mode and energy will be saved.
The efficient room and workstation control unit provides in addition a continuously monitoring of the environmental conditions, operating parameters and error messages. Combined with the MK remote diagnostic system the engineers of MK are able to give assistance to the and even to warn them ahead of faults and damages. Thus, the service effort is reduced to a minimum, with increased safety of the system and cost-efficient personnel deployment.
