ACA - Ash Content Analyzer
With a completely new and innovative measuring principle, the emtec ACA Ash Content Analyzer measures the total filler content and the individual fillers, which are typically used in the paper industry, of paper and board. Compared to the traditional combustion method, the ACA measures non-destructive and provides the results within seconds.
With the combustion method according to ISO 2144, DIN 54370, TAPPI T 413 and 211, which is traditionally applied in the paper industry, the total content and a few selected individual fillers can only be determined through an extremely time- and energy-consuming and in routine operation relatively inaccurate combustion of the samples at different temperatures (+/- 5%, operator dependent!). The combustion method is also disadvantageous due to its destructive measuring procedure.
By the use of the emtec ACA Ash Content Analyzer with its new and innovative measuring principle the total ash content (fillers and pigments), but also the percentage content of the typical fillers in the paper industry can be determined within seconds without combustion of the samples, i.e., non-destructive.
The quick measuring procedure leads to an almost instant availability of measuring results and therefore allows for an indeed immediate reaction to changes in the process:
- Immense material savings can be achieved through the reduction of process fluctuations
- The consumption of fillers can be reduced, as the immediate availability of results and the high accuracy of the ACA enables the narrowing down of the specifications for the filler content in the finished product, resulting in a much more efficiently organized process optimization (e.g. retention optimization)
- Costs for energy of the combustion process can be saved. Thus, the use of the new measuring device guarantees a fast "return on investment" by a substantial reduction of costs in material, time, and energy
