Abstract: A Method of correcting a multi-path absorbance measuring system is suggested. The multi-path absorbance measuring system has a plurality of n measuring path: The method is executed by correcting the signal of the measuring paths based on a determined linearization function.

Abstract: A fluidic system is provided which is adapted to perform optical analysis of a fluid. The system comprises a first capillary, at least one waveguide which is adapted to guide light and at least one second capillary. The first capillary comprises at least one first opening for receiving an end of the at least one first waveguide and it comprises furthermore at least one second opening for receiving a first end of the at least one second capillary, whereby a fluid communication between the first and the second capillaries is provided. The end of the at least one waveguide is arranged to emit light into the at least one second capillary.

Abstract: A rotatable handgrip shifting device (10) that is mountable on a bicycle handlebar and connected to a bicycle gear changing mechanism by a cable within a tube and reversibly operable at discrete shift points corresponding to the gears of the bicycle gear changing mechanism. The shifting device (10) includes a handgrip (34) rotatable about the handlebar, a spool (30) rotatable with the handgrip (34) and a housing (12) that secures the shifting device (10) to the handlebar. The housing (12) includes a gear display (18) denoting a plurality of discrete shift points of the gear changing mechanism. A flexible member (40) includes at one end a pointer (44) and a spool tab (42) at another end. The pointer (44) is reciprocally displaceable along the gear display (18) in response to rotation of the handgrip (34).

Abstract: A method for producing a capillary comprises the steps of providing first a capillary having a uniform inner width throughout its length, introducing then an etchant into the capillary, and producing a temperature gradient over the length of the capillary in such a way that a temperature-controlled increased expansion of the inner width of the capillary will take place during the etching process in the heated region thereof. A capillary produced in this way is excellently suitable for use in an electrophoresis device.

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.
