Density Measurement Autopycnometer
Overview:
Using volume measurements to achieve density, a gas pycnometer obtains data by pressurizing the sample cell (stainless steel) with Helium. A valve is then opened to a separate chamber, and the pressure changes within the chamber. Boyles law is then applied for sample volume calculations (info HERE). User inputs mass before experiment. Non-elutriating sample cells are available. Samples must be in solid state to be compatible.
Important Limitation:
- Solid samples only
- Ultrahigh purity compressed gas regulated to a pressure of 20 psig (see accessories).
- Helium is recommended
- Mass must be entered by user
- Digital pressure display resolution of 0.0001 pounds per square inch (psi).
