Title: Measurement of oil mist density
Inventor: ISHIGAKI HARUHISA
IPC: G01N5/02
Filed: 1982-07-02
Abstract: PURPOSE:To enable measurement by a simple technique by a method wherein oil mist in a reflux gas trapped into a filter is extracted by an n-hexane which is vaporized away with a thermostat to determine the weight of oil. CONSTITUTION:Oil mist in a reflux gas is trapped into a filter with a high volume sampler. Then, the filter is broken into fine pieces and put into a test tube with a common cock. After n-hexane is added thereto, the test tube is shaked rapidly to mix them thoroughly to extract the oil mist trapped into the filter. Subsequently, the oil mist thus obtained is filtered and washed with the n-hexane, vaporized away with a hot plate and weighed to determine the weight of oil by subtracting the weight of the filter before the trapping of the oil mist from the results. On the other hand, the filter is impregnated with a known amount of oil and the extraction rate of the n-hexane is obtained by the same technique. Finally, the density of the oil mist is calculated from the weight of oil and the extraction rate of the n-hexane.
