Whatman 1830-10095 is an HGF61 series glass microfiber roll filter membrane, compatible with β - ray automatic monitoring devices. The following are precise and detailed parameters: 1. Basic specifications and parameter details Product number 1830-10095 (Whatman HGF61 series) Brand Whatman (under Cytiva) Product typeHGF61 glass microfiber roll filter membrane (paper tape)Size specification 40mm × 17m, shaft inner diameter 28mm, 1 roll/package core material borosilicate glass microfiber, containing high-purity organic adhesive. Appearance color is white roll, texture is uniform, and the hair surface is upward. Core performance parameter details: retention efficiency of 0.3 μ m, standard particle retention rate>99.995%, suitable for high-precision PM monitoring by beta ray method. Key characteristics include hydrophobic surface, low water vapor adsorption, low non-specific adsorption, good weight stability, high mechanical strength, suitable for automatic paper feeding, 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 medium flow sampling basis weight of about 85g/m ² (HGF61 series universal typical value). III. Adaptation and Application Parameter Details Core Application Beta Ray Method PM2.5/PM10 automatic continuous monitoring, environmental air automatic monitoring station sampling, infrared weighing analysis adaptation instrument adaptation Thermo FH62C14, 5014i, spotlighting Sharp-5030 and other mainstream β - ray automatic monitoring instruments
