Emtec ACA – Ash Content Analyzer
emtec ACA – Ash Content Analyzer
The emtec ACA Ash Content Analyzer offers a fast, reliable and accurate determination of the total mineral filler content and the percentage content of the individual filler components in paper, board, plastic films, pulp and handsheets.
The combustion method (according to DIN 54370, ISO 1762 and 2144, TAPPI T 413 and 211) is the standard test method in the pulp and paper industry, which is used to determine the total ash content and a few selected individual fillers of a paper or board sample. The method is very time consuming, dependent on the operator (low accuracy up to 5%), destructive, since the sample is burned at two different temperatures, once at 525°C, and if necessary, additionally at 900°C. Both temperatures provide only limited information. A similar approach applies to foil producers.
All standard fillers, which can be detected by the device are calcium carbonate, clay, talcum, titanium dioxide, barium sulfate and iron oxide. Further components can be evaluated by taking a closer look at the x-ray fluorescence spectrum, which can be done with the emtec PC software. A complete measurement takes approx. 60 seconds and the test is nondestructive. Compared to the combustion method, the ACA is much faster, a lot more accurate and allows a much deeper look into the paper. All this helps to optimize the production and converting process, because results are available almost instant, which enables very fast interventions in the process, if necessary. An optimal production and converting automatically leads to a better and constant product quality and a significant saving of cost.
