Abstract: A packing composition (110) for inserting into a fluidic device (100), the packing composition (110) comprising a packing material (114) adapted for separating different components of a fluid and an elastic network (115) in which the packing material (114) is embedded.

Abstract: A column device comprises a stationary phase having a plurality of particles adapted for interacting with a mobile phase in order to separate different compounds of a sample fluid dissolved in the mobile phase, a housing for at least partly housing the stationary phase, and a separator separating sections of the stationary phase and being force-coupled with the housing.

Abstract: An apparatus for packing a chromatography column with a granular packing medium is disclosed. The apparatus includes a chamber adapted to hold a mixture of the packing medium and a liquid. The chamber is in fluid communication with a pump and the column. A vibrator is positioned so as to agitate the mixture within the chamber. The invention also includes a method of packing the chromatography column by forming a mixture comprising the packing medium and the liquid, positioning the mixture within the chamber, agitating the mixture, and pumping liquid into the chamber thereby forcing the mixture through the column.

Abstract: An apparatus for the recognition of exchangeable parts in an analytical measuring instrument or in an analytical measurement system with several analytical devices, which contain exchangeable parts has identification modules each attached to an exchangeable part, and transmit-receive devices which can receive information signals from an identification module and send information signals to an identification module, and a control device which evaluates the information from an identification module. The control device can cause a message to be displayed on a display device, if the information read out from an identification module does not fulfill certain conditions, for example with regard to the quality of the corresponding part.

Abstract: A separation column for chromatography, such as for liquid chromatography or supercritical fluid chromatography, comprises a separation tube made of a ceramic composite material and a stationary phase packed into the separation tube. The column has a high pressure stability and smooth inner surface leading to improved chromatographic properties.
