Abstract: A system and method of incubating a liquid is provided. The system is well-suited for incubating small volumes of liquid at high temperatures. The liquid may be a reaction mixture comprising a glycoprotein. During the incubation process, oligosaccharides may be removed from the glycoprotein.

Abstract: Polar, monolithic CEC columns having an amine and/or cyano functional stationary phase are used to separate complex mixtures of saccharides. Using the positive-ion mode of detection for neutral saccharides, detection conditions were optimized to low-femtomole sensitivities with the use of an ion trap mass spectrometer. The described column technology provides a universal system for separating a wide range of carbohydrates: mono- and oligosaccharides with the intact reducing end, as well as saccharide alditols.

Abstract: Apparatus for and method of open-tube supercritical fluid chromatography.

Abstract: Arrangement for separation of suspensions or emulsions from liquids by flotation having a flotation space widening from the bottom upwards, to be again narrowed from the place of its largest width upwards. The flotation space is formed by a partition wall within a tank, the supply of cleaned liquid terminating into the lower part of the flotation space. The flotated foam is removed at the surface of the top part of the flotation space, with transfer openings above the widest place of the flotation space terminating in a collecting space of cleaned liquid defined by the partition wall and the wall of the tank, a rectifying wall being provided in front of said transfer openings for preventing passage of the flotated suspension to the collecting space of cleaned liquid.
