The Difference Between Quantitative Filter Paper and Qualitative Filter Paper

The difference between quantitative filter paper and qualitative filter paper is mainly the amount of ash generated after ashing: qualitative filter paper does not exceed 0.1%, and quantitative filter paper does not exceed 0.007%.

Quantitative filter paper is mainly used for ashing weighing analysis experiments after filtration, that is, gravimetric analysis test and corresponding analytical test in quantitative chemical analysis, the ash weight of each filter paper after ashing is a fixed value; qualitative filter paper is used for general Filtration, ie qualitative chemical analysis and corresponding filtration separation.

Ashless filter paper It is a quantitative filter paper with an ash content of less than 0.1 mg, which is negligible on the analytical balance.

Qualitative filter paper use: Analytical laboratories commonly used filter paper as a filter medium to separate the solution from the solid.

Quantitative filter paper use:

1, the difference between quantitative filter paper and qualitative filter paper is mainly the amount of ash generated after ashing: qualitative filter paper does not exceed 0.1%, and quantitative filter paper does not exceed 0.007%.

2, ashless filter paper It is a quantitative filter paper, its ash content is less than 0.1mg, this weight is negligible on the analytical balance.

3, pay attention to the quantitative filter paper and qualitative filter paper are two concepts of cellulose filter paper, not applicable to other types of filter paper such as glass microfiber filter paper.
