摘要： An apparatus and method are disclosed which allow the size of a particle suspended in a medium to be determined virtually independent of the materials'refractive index. The apparatus includes a light source, a sample holder, a detector and a spatial filter. The method of the invention comprises passing the medium containing the particle through a beam of collimated light so that the light which contacts the particle will be scattered; deterring the light which was scattered by the particles from being detected, detecting the light which was not scattered by the particle; and determining the size of the particle from the decrease in the light intensity incident on the detector.

摘要： A column holder for on-column photometric detection capillary liquid chromatography incorporating a body and a pair of straight edges attached to the body. The straight edges can be conveniently made from a razor blade. The body has two passageways through it that are transverse and intersecting. The first passageway is dimensioned so that a capillary column can be slipped into it or removed from it by hand. The other passageway is for the passage of a light beam from a liquid chromatography photometric detector. The straight edges are slightly separated to form an optical slit in front of the capillary column and are securely clamped to the body of the column holder. A capillary column can be removed from the column holder and be replaced with another capillary column without damaging it and without the necessity of repositioning the slit.
