摘要:
A method of filtering a liquid sample that includes passing a sample comprising at least one biological organism through a filter membrane at a passive water volume flux of at least 10 L/m2·h·psi, wherein the filter membrane comprises a Bubble Point pore size of no more than 1.0 μm, thereby retaining at least one biological organism on the surface of the membrane; and detecting the at least one biological organism retained on the surface of the filter membrane.

摘要:
A method of determining the quality of oil by irradiating the oil at a first wavelength, e.g., of about 470 nm, measuring a level of fluorescence of the oil at a second wavelength, e.g., of about 520 nm, comparing the measured fluorescence level to a predetermined threshold level to determine whether or not the oil quality is acceptable. The oil is preferably discarded if the measured fluorescence level exceeds the predetermined threshold level, which can be generally dependent on the oil composition. The fluorescence is correlated to the level of polar components in the oil. Also described are devices for determining the quality of oil via fluorescence.
