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
A pycnometer is a laboratory glassware device used to measure the density of liquids and solids. It typically consists of a small, calibrated bottle with a close-fitting ground glass stopper. By weighing the pycnometer filled with a sample liquid or solid and then empty, the density of the material can be calculated.

Who invented the pycnometer?
The pycnometer was invented by French chemist Augustin Louis Cauchy in the early 19th century. He developed the device to measure the density of liquids and solids with high precision.
When was the pycnometer invented?
The pycnometer, a device used to measure the density of liquids, was invented in the early 19th century by French chemist René Just Haüy.
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.
How do you use a pycnometer?
To use a pycnometer, you first weigh the empty pycnometer. Then, fill it with the material to be measured and weigh it again. The difference in weight gives you the mass of the material. Once you know the volume of the pycnometer, you can calculate the density of the material.
Which test should be performed to detect specific gravity of fats and oil?
The specific gravity of fats and oils can be detected using a method called the pycnometer method. In this test, a pycnometer (a specific type of glass bottle with a known volume) is filled with the oil or fat sample, weighed, and then filled with a known reference liquid (often water) to determine the specific gravity.

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.
