Description
Collection of precipitation for analyzing organic components as well a mercury in the precipitation, the choice of the best fitting contact material like sample funnels is very important. In these cases PTFE and DURAN-glass, in some cases also stainless steel are preferable to HD-polyethylene. Collecting precipitation for acidifying components HD-PE is seen as the appropriate contact material to the sample. Eigenbrodt has developed a complete series of collection funnels to fit the collector the application.
Those funnels are available for the collector types NSA 181, NSA 181/K, NMO 191, UNS 130 and BUS 125 with 500cm² collection area (490 cm² with DURAN-glass), which provides good collecting capacities of nominal 50ml sample per 1mm of precipitation.
The models BUS 100 and NSA 171 come with smaller collection funnels out of borosilicate-glass as they follow specific norms and guidelines.
