HGF61 glass microfiber roll filter membrane (paper tape)

Whatman 1830-6236 is an HGF61 series glass microfiber roll filter membrane, compatible with β - ray automatic monitoring devices. The following are the precise parameters: 1. Basic specifications and parameter details. Product type: Whatman (under Cytiva)HGF61 glass microfiber roll filter membrane (paper tape)The size specification is 30mm × 20m, and the inner diameter of the shaft is suitable for mainstream β - ray monitoring devices. The core material is borosilicate glass microfiber in 1 roll/pack, containing high-purity organic adhesive. The appearance color is white roll, and the texture is uniform. The core performance parameters are detailed. The interception efficiency is 0.3 μ m, and the standard particle interception rate is greater than 99.995%. It is suitable for high-precision monitoring of β - ray method. The key characteristics are hydrophobic surface, low water vapor adsorption, low non-specific adsorption, good weight stability, high mechanical strength, and automatic paper feeding. The temperature resistance performance can withstand up to 180 ℃. It is suitable for infrared weighing and high-temperature pre-treatment filtration characteristics. The medium filtration speed, high load capacity, and not easy to block. It is suitable for medium flow sampling with a basis weight of about 85g/m ² (HGF61 series universal typical value). Adaptation and Application Parameter Details Core Application β X-ray method PM2.5/PM10 automatic continuous monitoring, environmental air automatic monitoring station sampling, infrared weighing analysis adaptation instrument adapted to specific models of β - ray automatic monitoring instruments such as Tianhong TH-2000 series
