Abstract
The mass separative performance of a turbomolecular pump is studied theoretically and experimentally. It is predicted theoretically that the separation factor of a single blade row varies considerably with the extracted gas flow from the low pressure side of a row and varies slightly with the composition of the gas. But the measured separation factor does not vary with the gas flow. This discrepancy between theory and experiment is explained by the fact that the extracting speed in the free molecule flow range is inversely proportional to the square root of molecular weight.
