Abstract
A magnetic suspension technique has been developed for use in making absolute density measurements on cryogenic fluids at low temperatures and elevated pressures. Adapting a method, previously used at room temperature, for PVT work in this region required several modifications. This apparatus can be used at any temperature below ambient and at pressures up to 340 atm. The density of saturated liquid nitrogen at 77.46 K has been determined in order to evaluate its performance.Keywords
