Product Details
Grade Quartz A is a fine porosity binderless quartz (SiO2) glass microfiber that offers a 99.999% efficiency in air filtration for the retention of 2.20µm particles, with an effective temperature range of up to 1000 °C. This media meets or exceeds the physical, performance, and elemental requirements for EPA PM10 and ambient air monitoring methods. It has a flow rate of 1.1 - 1.35 m3/min, with a resistance of 95mmH2O at 10.5 ft/min, and a loss on ignition of less than 6%. The tensile strength is measured at 215g/15mm according to ASTM D828, while the machine direction tensile strength is 7.3 lbs/in as per TAPPI T494. Grade Quartz A is primarily utilized in air pollution monitoring, atomic absorption spectroscopy, flame emission spectrometry, and applications requiring extremely critical analysis. It is particularly effective for use in acidic gases (excluding hydrofluoric) and aerosols, as well as stacks and flue gas monitoring. The media features uniform screen and felt sides with consistent density in machine direction and cross direction, demonstrating excellent lot-to-lot reproducibility, and is manufactured using a reverse osmosis water filtration system.
