Comparison Of Quantitative Filter Paper And Qualitative Filter Paper

Similarity
Both the quantitative filter paper and the qualitative filter paper are cellulose filter papers and are not suitable for other types of filter paper such as glass microfiber filter paper.

Differences
Qualitative filter paper is used for qualitative chemical analysis and corresponding filtration separation; quantitative filter paper is used for gravimetric analysis test and corresponding analytical test in quantitative chemical analysis.

The function of the quantitative filter paper is mainly used for the ashing weighing analysis experiment after filtration. The ash weight of each filter paper after ashing is a fixed value.

The qualitative filter paper is used for general qualitative analysis and for filtration of precipitates and suspensions in solution. While the amount of ash generated after ashing differs the quantitative and qualitative filter paper. The qualitative filter paper does not exceed 0.13%, and the quantitative filter paper does not exceed 0.0009%.

Ashless filter paper is a quantitative filter paper with an ash content of less than 0.1 mg, which is negligible on the analytical balance. Because the qualitative filter paper’s pulp is treated with hydrochloric acid and hydrofluoric acid and washed with distilled water to remove most of the impurities in the paper fibers.
