HGF61 glass microfiber roll filter membrane (paper tape)

Whatman 1830-10091 is a HGF61 series glass fiber roll filter membrane designed specifically for automatic monitoring of PM2.5/PM10 beta rays, compatible with mainstream automatic sampling instruments. The following are precise and detailed parameters: 1. Basic specifications and parameter details Product number 1830-10091 (Whatman HGF61 series) Brand Whatman (under Cytiva) Product typeHGF61 glass microfiber roll filter membrane (paper tape)Size specification 40mm × 150m, shaft inner diameter 28mm, 1 roll/pack core material borosilicate glass microfiber, containing special organic adhesive. Appearance color: white roll, uniform texture. 2. Core performance parameter details: interception efficiency: 0.3 μ m, standard particle interception rate>99.995%. Suitable for high-precision monitoring of key characteristics using the β - ray method: hydrophobic surface, low water vapor adsorption, low non-specific adsorption, excellent weight stability, high mechanical strength, not easy to break, temperature resistance up to 180 ℃. Suitable for infrared weighing and high-temperature pre-treatment filtration characteristics. Medium filtration speed, high load capacity, not easy to block. Suitable for automatic sampling at medium flow rate with a basis weight of about 85g/m ², consistent with the GF10 series. Suitable for conventional weight method analysis. Adaptation and Application Parameter Details Core Application β Ray method PM2.5/PM10 automatic continuous monitoring, daily sampling of ambient air automatic monitoring station, infrared weighing analysis adaptation instrument adaptation Thermo FH62C14, 5014i, spotlighting Sharp-5030, Tianhong TH-2000 and other mainstream β - ray automatic monitoring instruments
