Yes, filter paper is generally categorized into two main types: qualitative and quantitative. For example, the USA Lab Qualitative Filter Paper - Slow 2um Micron - Various Sizes is a qualitative 2 micron filter paper. This type is ideal for general laboratory filtration where precise residue measurement is not required, offering fine particle retention and suitable flow rates for a variety of applications. In contrast, quantitative filter paper—such as a 2.5 micron filter paper—would be used when accurate residue mass and minimal ash content are necessary for analytical tasks.
