◆ More-Details:
Qualitative filter paper is used when there is no requirement for the material and paper to be ashed (burned), as is necessary in a gravimetric (quantitative) laboratory analysis.
◆ Features
Extremely fast filtering with excellent retention of coarse particles and gelatinous precipitates such as ferric hydroxide and aluminum hydroxide. Very useful as a rapid filter for routine clean-up of biological fluids or organic extracts during analysis. Used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.
