To produce quantitative papers, the high-quality raw materials (cotton linters with 98 % of alpha-cellulose content) are treated to reduce mineral content and therefore get an ignition residue of 0.01 %.
Qualitative papers are also made of high-quality raw materials (refined pulp & linters with 95 % of alpha-cellulose content) but without any reduction of mineral content. Their ignition residue is 0.1 %.
Quantitative and qualitative papers are mostly used in analytics due to their quality.
Qualitative and technical papers can be used in analytics for pre-filtration steps but predominantly cover technical filtration.
