Quartz frits are porous discs made from high-purity quartz glass. They are used in a variety of applications where a porous filter is required to separate solid particles from liquids or gases. Some of the common uses of quartz frits include:

• Chromatography: Quartz frits are commonly used in chromatography applications to separate different components of a mixture. They act as a stationary phase and allow the sample to pass through while retaining the stationary phase particles.
• Gas diffusion: Quartz frits are used as gas diffusion filters to introduce gases into reaction vessels or to remove gas bubbles from liquids. They are commonly used in gas-liquid reactions, where gases need to be diffused into the liquid phase.
• Fluidized bed reactors: Quartz frits are used as support structures in fluidized bed reactors, where a solid catalyst is suspended in a fluid and used to catalyze reactions. The frits help to distribute the fluid evenly through the reactor and provide a large surface area for the reaction to take place.
• Sample preparation: Quartz frits are used in sample preparation for analytical chemistry applications such as HPLC (high-performance liquid chromatography) and GC (gas chromatography). They are used to filter samples and remove particulate matter before analysis.
• Filtration: Quartz frits are used as filters in a variety of applications where a porous filter is required to separate solids from liquids or gases. They are commonly used in high-temperature gas filtration applications.
• Overall, quartz frits are a versatile material that finds use in various industrial and scientific applications due to their unique properties.
