A gas pycnometer operates by detecting the pressure change resulting from displacement of gas by a solid object. Expanding a quantity of gas at known pressure into an empty chamber and measuring the pressure establishes a baseline.Then a sample is placed in the chamber and the chamber is resealed. The same quantity of gas at the same pressure is again expanded into the sample chamber, and the pressure is measured. The difference in the two pressure combined with the known volume of the empty sample chamber allows the volume of the sample to be determined by way of the gas law. --GOLD APP INSTRUMENTS

Who invented the pycnometer?
1000-1048: Pycnometer: Abū Rayhān al-Bīrūnī
When was the pycnometer invented?
According to the Wikipedia article on the gas pycnometer, the first patent was filed by John E. Shea on 13 Nov 1978 and it was issued on 08 Apr 1980.
What are the parts of pycnometer?
A pycnometer consists of a glass or metal container with a precise volume, a stopper or lid to seal the container, and a thermometer to measure the temperature of the liquid being tested. It may also have a hook or loop for suspending it in a fluid to measure its specific gravity.
Why the shape of pycnometer cap is conical?
The conical shape of the pycnometer cap helps reduce turbulence during filling, allowing for more accurate volume measurements. It also helps prevent air bubbles from getting trapped, ensuring proper density readings. Additionally, the conical shape minimizes moisture buildup on the cap, which could affect the density measurements.
How do you use a pycnometer?
Take G-DenPyc 2900 as an example: step 1. weight sample mass; step 2. put sample into sample chamber; step 3. cover sample chamber and switch gas on; step 4. input sample mass into analyzer software and click "start" to operation; step 5. about 5 mins to wait sample results.
How do you properly use a pycnometer for measuring the density of a substance?
To properly use a pycnometer for measuring the density of a substance, first clean and dry the pycnometer. Then, weigh the empty pycnometer and record the mass. Fill the pycnometer with the substance, making sure there are no air bubbles. Weigh the filled pycnometer and record the mass. Calculate the density using the formula: density (mass of substance)/(volume of pycnometer).

Why the pycnometer method more accurate than the hydrometer method?
The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.
