Brief introduction: YG - 97 - a type of high-performance mercury injection apparatus suitable for solid particles or block the determination of pore size distribution curve of solid materials, especially the aperture more than 100 nm in the analysis of the sample. YG - 97 - a type of mercury injection device, according to the principle of capillary pressure, using the mercury on the wettability of solid samples, under the effect of applied pressure, the mercury into the solid channel. Under different pressure according to the Washburn equation, by measuring the amount of mercury injection volume can know the size of the hole radius of appropriate pore volume, which can be the pore size distribution curve of porous materials (porosity). YG - 97 - a type of mercury injection apparatus meet ISO 15901-1:05 international standards and national standards GB/T 21650.1-2008. Features: 1. The ultimate vacuum 0.05 Pa; 2. Resistance to high pressure, vacuum, blank value is small, high accuracy, strong stability. 3. The pump speed can be stepless speed regulation control of speed and add pressure. 4. The measuring control system: the pressure measurement, capacitance measurement, vacuum measurement of three parts. 5. Mercury has a strict security measures, effectively avoid mercury vapor's influence on the indoor environment. Technical indicators: Hole diameter measuring range: 30 nm to 600 microns; Pore volume test range: 0.3 to 3.5 cc; Accuracy: 0.5% or less; Analysis station: station 1 independent samples, sample room's largest volume 15 cc; Working pressure range: 0.01-50 mpa, the dual pressure measurement technology; Test pressure: 60 mpa; Static pressure head: 20 MMHG or less; Blank value: 50 mpa at about 0.25 ml; Limiting vacuum bipolar mechanical vacuum pump, vacuum pump: 0.05 Pa; Analysis model: the accumulative total pore volume, accumulative specific surface area, average pore diameter and pore diameter distribution, porosity) curves, pore throat ratio, mercury withdrawal/mercury injection curve and so on; Sample types: solid particle or block solid samples;
