Analytical method and apparatus for analyzing substances |
| abstract |
An analytical method which comprises sampling a predetermined amount of a liquid sample, bringing the sample to a vapor-liquid equilibrium at a predetermined temperature and pressure, separating the resultant gaseous and liquid fractions from each other, and analyzing the gaseous fraction as a gas sample and the liquid fraction as a liquid sample, and an apparatus for practicing the analytical method. By this method or apparatus, the light and heavy fractions of a substance can be simultaneously analyzed in composition and chemical structure. This enables the modification and the service life of a chemical substance like a lubricating oil, in which the qualities may change with the passage of time, to be estimated or foreseen. |
