2) Working Principle
This automatic gas pycnometer is designed based on the gas displacement method. It works by introducing an analysis gas, such as helium or nitrogen, into a sealed sample chamber of known volume and then expanding it into a precise reference chamber. By recording the pressures before and after expansion, the volume can be accurately measured.
① Gas Pre-heating
The gas pre-heating is achieved through a precise temperature-control system that maintains a consistent temperature within a narrow range, leading to more accurate measurements. The temperature-control system is a crucial feature of the automatic gas pycnometer design.
② Gas Displacement
The gas is introduced into the sample chamber, displacing the empty space and penetrating the pores of the sample.The chamber lid, which provides a tight seal, ensures that the sample chamber is completely sealed and prevents any gas leakage during the measurement process.
③ First Pressure Equilibrium
Pressure 1 is recorded after the first equilibrium. The temperaturecontrol system maintains a stable gas temperature, allowing pressure to equilibrate to lower 0.005 psig/min. A high-resolution transducer measures the pressure inside the sample chamber after equilibration.
④ Gas Expansion
The gas is then allowed to expand into a reference chamber. Dual built-in reference chambers match the free space in the sample chamber for accurate results. The appropriate chamber is selected automatically based on the sample cup size, making it an ideal choice for precise density measurements.
⑤ Second Pressure Equilibrium
Pressure 2 is recorded after the second equilibrium and the gas is vented into the atmosphere. After that. the result is calculated. An integrated vacuum pump extracts gas to improve purge efficiency and reduce measurement errors.
3) Industries We Serve
The BetterPyc 380, which complies with many ASTM and ISO standards, is a versatile instrument that can be used in a wide range of industries. It is able to accurately measure the density of a wide range of materials, the solid content in slurries, and the open cell content in plastic foams, enabling process optimization and quality assurance in relevant industries.
|Powder Metallurgy||The skeletal density of metal determines its properties and processing results, and the performance of metal structures can be predicted from powder skeletal density.||ASTM D923-22||Cellular Plastic||Plastic foam properties vary based on the open/closed cell ratio. Insulation foams reduce thermal conductivity
with trapped gas in closed pores. Flotation devices float due to closed air-filled pores.
|Pigments||Dried film density helps determine the VOC content of clear and pigmented coatings, which is regulated by the government.||
|Pharmaceutical||Product density determines and controls active or excipient composition. Product forms, purity, etc. can be determined by comparing measured density with theoretical and historical values.||
|Cement||True density is essential for ensuring the quality and performance of cement powder, influencing its flowability, strength, and environmental impact.||T/CCAS 012||Soil||Soil specific gravity (SG) must be corrected due to precipitate formation after drying. A precipitate with lower
SG leads to lower results, while one with higher SG leads to higher results.
|ASTM D5550 -14|
|Food||True density is crucial for ensuring the consistency and quality of dry food, affecting its processing, shelf life, and
|-||Calcined Coke||The density of calcined petroleum coke is a crucial quality specification for coke calcination, as it affects the properties of the resulting artifacts.||ASTM D2638-21|
|Powder Coating||Total solids content helps determine coating coverage potential. Dry pigment blends are monitored by
comparing measured and theoretical densities based on composition.
|ASTM D5965-20||Refractory||True density is useful for: classification, identifying chemical differences, revealing mineral phases or alterations, determining total porosity and calculating results for other tests.||ASTM C604-02|
