Answer / Qumesh Ul Hasan

Glass fiber filters are used in analytical chemistry due to their ability to retain fine particles and their high chemical resistance. They are often used in filtration processes where the sample contains small particles that can clog other types of filters or damage equipment. Glass fiber filters are also useful when working with volatile, corrosive, or thermally unstable samples. Additionally, they have low absorbance in the UV-Vis region and minimal bleed, making them suitable for use with spectrophotometric analysis.
