PCT No. PCT/FI95/00016 Sec. 371 Date Jul. 9, 1996 Sec. 102(e) Date Jul. 9, 1996 PCT Filed Jan. 17, 1995 PCT Pub. No. WO95/20153 PCT Pub. Date Jul. 27, 1995The invention concerns a method and an apparatus for determination of the cloud point of oil. In the method according to the invention the cloud point is determined from a turning point on the oil cooling curve. The method of the invention may be realized in an apparatus comprising a cooling jacket for cooling the oil sample, a measuring space essentially shaped as oppositely located cones, a temperature indicator for determination of the oil cooling curve. With the invention the cloud point of oil can be determined quickly and reliably, the measuring cell of the invention allows a very high degree of exactitude in measurements, the measurement results are well reproducible and the invention makes it possible to bring about a method and an apparatus allowing a fully automatic operating analyzer for determination of the cloud point of oil. |
