  • Publication number: 20150075564
    Abstract: The invention relates to the preparation of samples on mass spectrometric sample supports with dispensing of liquids, and particularly to devices and methods to clean the dispenser. During dispensing of hundreds of samples, solved material may crystallize over time as deposit at the capillary tip of the dispenser, which impedes the vertical detachment of the drop in the medium and long run. Therefore, frequently cleaning the capillary tip is essential for a robust operation of the preparation device. The invention proposes to automatically clean the dispenser tip by creating a drop of washing fluid, such as pure solvent, fully enclosing the dispenser tip. The washing fluid is fed through a channel outside the central dispenser capillary to a location slightly above the capillary tip. The size of the hanging drop of washing fluid is photometrically regulated and monitored to prevent it from falling off prematurely.

  • Patent number: 8568104
    Abstract: The proportioner (10) has a variable speed controlled DC motor (12) having a gearbox (14) and crankshaft (16) at either end which are connected to reciprocating piston pumps (18). The outputs (18a) of the two pumps (18) are fed to a manifold (22) where the pressure of each output is measured. The user sets a setpoint pressure (e.g. 1000 psi) and the controller (26) then compares the pressures of the two components and controls the higher of the two relative to the setpoint. Ratio assurance is monitored by continuing to look at both output pressures. If one side falls below a predetermined percentage of the setpoint (50% in the preferred embodiment), an alarm may be raised or operation stopped.

  • Patent number: 8540937
    Abstract: A system and/or method formulates a chemical solution using both volumetric and weight based measurements of components of the chemical solution. The components of the chemical solution include water and at least one other component, which may take any form, such as, without limitation, liquid, solid, powder or gaseous form. Formulation of the chemical solution is administered by combining water with the one or more other components at an output port, from which this combination is dispensed to a solution storage tank. In response to a user's request to formulate a specified amount of the chemical solution, the volume of water provided to the output port is monitored by a flow meter and the weight of the other component(s) provided to the output port is monitored by one or more load cells. Based on such monitoring, appropriate amounts of water and the other component(s) are combined together to formulate the specified amount of the chemical solution in the solution storage tank.

  • Patent number: 8484949
    Abstract: A method is provided for monitoring of the functionality of an After Treatment Injector (ATI) for injection of a fluid in an engine exhaust gas system upstream of an exhaust gas treatment unit. The monitoring is performed by using a pressure sensor which detects the pressure of the fluid delivered to the ATI for a specific condition or injection cycle. The pressure sensor is located downstream of a flow regulator and upstream of the ATI in a conduit for supplying of a substance from a container to the ATI. An ECU is programmed to perform a predetermined sequence of opening and closing commands for the flow regulator and the ATI, furthermore perform a frequency analysis of the measured pressure value in order to monitor the functionality of the flow regulator, the ATI and the pressure sensor. The method is adapted to be used in connection with an On Board Diagnosis (OBD) system.

  • Patent number: 8448817
    Abstract: In the method of optimizing the dosage-dispensing process of a dosage-dispensing device, an examination takes place prior to a first dosage delivery, whether at least one flow parameter relating to the dosage-dispensing process is stored in the memory module of the dosage-dispensing unit. If a stored flow parameter is found to be present, said flow parameter is called up from the memory module. If no store flow parameter is present, a flow parameter is requested by the user by entering a request, a flow parameter is called up from a central database, or at least one flow parameter is determined by means of the first run of the dosage-dispensing process based on a default setting of the dosage-dispensing program. With the at least one flow parameter, the dosage-dispensing program is directly adapted, at least one run of the dosage-dispensing process is performed with the adapted dosage-dispensing program, and/or the at least one flow parameter is stored in the memory module.
