The test gas has a wide range of types and high accuracy, and is suitable for gas permeation testing in the fields of fuel cell proton exchange membrane gas permeability testing, hydrogen permeation of hydrogen storage materials, gas density of bipolar plate materials, and natural gas storage materials.   Test principle Place the processed sample between the high-pressure chamber and the low-pressure chamber, and the low-pressure chamber is connected to the gas chromatograph through a quantitative loop. At the set test temperature, use a vacuum pump to evacuate the gas system, and then add a certain pressure of test gas to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the action of the pressure gradient, the gas penetrates from the high-pressure chamber to the low-pressure chamber through the film. The system injects the gas that penetrates into the low-pressure chamber into the gas chromatography column and separates it into various components, and calculates the gas permeability, gas permeability coefficient and other barrier performance parameters of each component.   Standard GB/T 20042.3，GB/T 20042.6-2011，GB/T 1038.1-2022，ISO 15105-1   Specification Item Technical Parameters Test range 2.0×10-12~3.0×10-7 mol/(m2·s.Pa) Detection system Gas chromatography (GC), TCD detector Test gas Gases such as hydrogen, oxygen, nitrogen, carbon dioxide, carbon monoxide, methane, etc., single component or mixed component Gas pressure 0~300kPa Permeation module temperature control range 15~60℃ Temperature control accuracy ±0.1℃ Permeation area 50.24 cm2 Sample size Φ110 mm Sample thickness ≤2 mm Sample quantity 1 piece Power supply AC 220 V，50 Hz   Features Advanced gas chromatography analysis technology The instrument is equipped with an advanced gas chromatography analysis module and a new microcomputer temperature control system, which can achieve 16-step program temperature rise with high temperature control accuracy; it adopts multi-processor parallel working mode, and can be equipped with a variety of high-performance detectors.

Introduction AUTO GBM-L2 Dual-Pressure Methods Vacuum Decay Leak Detection Tester adopts the test principle of vacuum decay method/pressure decay to detect micro-leakage of finished packaging. It can be applied to packaging systems composed of vials, ampoules, Leakage detection of pre-filled needles, eye drop bottles, HDPE bottles, infusion bottles/bags and other pharmaceutical packaging, food packaging, and chemical industry packaging.   Test principle The host is connected to a sealed test chamber customized according to the sample. When performing the vacuum decay method test, the instrument evacuates the test chamber, and a pressure difference is formed inside and outside the sample. Under the action of the pressure, the gas/liquid in the sample enters the test chamber through the leak hole. The main engine uses the absolute pressure sensor and the differential pressure sensor to monitor the pressure change in the chamber to judge whether the sample leaks. When performing the pressure decay method test, the instrument fills the test chamber with a predetermined air pressure, and the gas in the test chamber enters the sample through the leak hole. The host uses absolute pressure sensors and differential pressure sensors to monitor the pressure changes in the chamber to determine whether the sample is leaking.   Standard ASTM F2338-2009(2013),  YY-T 0681.18-2020,  USP<1207.2>, ASTM F2095   Specification Item Parameters Absolute Pressure Testing Range (0 - 300) kPa Differential Pressure Testing Range (-2 - 2) kPa Detection Sensitivity 1 - 3 μm Balancing/Testing Time 1 - 3600 s Vacuum Purge Time 1 - 3600 s Set Flow Rate 0 - 3 mL/min Testing System Dual Sensor Technology/Dual Cycle Testing Testing Chamber Customized according to the sample Applicable Products Vials, Ampoules, Prefilled Syringes, Infusion Bottles/Bags, etc. Detection Principle Vacuum Decay Method/Pressure Decay Method Dimensions of the Main Unit 495 mm455 mm280 mm Ambient Temperature 20℃ - 25℃ Relative Humidity 40% - 60% Working Power Supply AC 220V, 50HZ   Features u Dual-Pressure Methods, to help solve testing difficulties The double combination of vacuum decay method and pressure decay method solves the problem of easy misjudgment and false negative for freeze-dried powder injections containing vacuum in the bottle using a single vacuum decay method.
