37 Functional description The sample beakers (16-1) are stored in the sample positions (16-2) in the sample rack. The transport handles (16-3) allow for the sample rack to be transported by hand so that it can be set down on and removed from the rack holder of the rack base. Several empty sample racks can be stacked on top of one another on the transport handles. The sample rack contains rinsing holes for emptying liquids in case of overflows and for cleaning. Cleaning The sample rack is not dishwasher-safe. Table 6 Sample rack versions Art. no. Beaker volume Number of beakers ml ml ml ml Sample Robot Pick&Place Functional description The Sample Robot Pick&Place is comprised of the following components: Main module Pick&Place Pick&Place module Peristaltic pump module Rack base Module base The OMNIS Sample Robot System is used for the automatic measurement of different organic and inorganic samples. The samples are stored, transported and processed through the components individually integrated in the system. 29

38 Sample Robot Pick&Place Functional description Main module Pick&Place Functional description All of the attached modules in the OMNIS Sample Robot System are supplied with electricity through the main module Pick&Place. The main lift with gripper and gripper arm is fastened to the main module Pick&Place. The gripper is used for transporting the sample beakers out of the sample racks and into the processing stations intended for this purpose. Once the processing of the samples has been completed, the gripper removes the sample beakers out of the processing stations once again and transports them back into the previously removed sample rack. The control hardware is integrated in the interior of the main module Pick&Place Pick&Place module Functional description The samples in the OMNIS sample robot system are analyzed on the Pick&Place module. The sample beakers are transported by the sample robot into the front sample position of the Pick&Place module. After the sample beaker has been put into place, the slide with the sample beaker moves under the titration head and the lift moves downward. The sensors installed in the titration head analyze the sample. After completion of the measurement, the sensors are cleaned with one of the pumps that are integrated in the pump module. The solution that is generated during this process is aspirated by an additional pump of the pump module and the lift with the sensors rises. Afterwards the slide moves back out again and the sample beaker is removed by the sample robot OMNIS peristaltic pump module Functional description 2 or 4 peristaltic pumps are integrated on the peristaltic pump module. 2 peristaltic pumps are assigned to each workstation in the OMNIS sample robot system. The upper peristaltic pump (numbered with 1 or 3) rinses off the sensors in the Pick&Place modules with solvent after the analysis of a sample. For this purpose, the solvent is aspirated from the rinsing canister through the peristaltic pump. If required, these pumps can also be used to dilute a sample with solvent or to bring it into solution prior to an analysis. The lower peristaltic pump (numbered with 2 or 4) aspirates the remaining solution out of the sample beaker during and after the rinsing procedure and routes it to the waste canister. 30

39 Functional description Optionally, up to 2 lid trays can be installed on the pump module. The Dis- Cover lid that was removed from the sample beaker is parked on the lid tray until it is needed again to seal the sample beaker. If malfunctions occur at the peristaltic pump, this will be displayed via LED at the peristaltic pump Functional description Peristaltic pump The peristaltic pump operates in accordance with the volume displacement principle. The pump tubing in the interior connects the inlet and the outlet of the peristaltic pump. This pump tubing is pinched off by four internal rollers. Media are aspirated in and out by this squeezing of the pump tubing and the volume displacement that results from it Rack base Functional description The rack base is the skeletal structure for the sample robot. The sample racks in which the sample beakers are located are stored on the rack holders of the rack base. The rack holders contain sensors that automatically detect which sample rack type is currently located on the individual rack base. The OMNIS sample robot system uses the sample rack type to detect which type of sample beakers are located in the sample rack. This information is passed along to the control which sets the gripper to the respective size of the sample beakers. If a sample rack that is still to be approached by the sample robot is removed, this is detected by the rack holders and passed along to the OMNIS sample robot system. This sample rack will no longer be approached by the sample robot and the absence of the sample rack will be displayed in the control. 31

42 Checking the delivery 4 Transport and storage 4.1 Checking the delivery 4.2 Storing the packaging Immediately upon arrival of the merchandise, check the shipment against the delivery note to ensure completeness and absence of damage. The product is supplied in extremely protective packaging together with the separately packed accessories. Keep this packaging, as only this ensures safe transportation of the product. 4.3 Lifting the sample robot Avoid lifting the sample robot after the initial installation whenever possible. The bigger M and L versions in particular need to be adjusted again after transportation. If it is necessary to lift the sample robot, try to avoid a sag by lifting the system on all four sides. Take the total weight of the system into account. Check the positioning accuracy of the sample robot after placing the sample robot down. If inaccuracies occur, Metrohm support will assist you. 34

43 Installation 5 Installation 5.1 Installation by Metrohm Installation of the products As a basic rule, the installation of the system and of the new products and modules is handled by trained and instructed specialists from the Metrohm Company and/or its representative. 5.2 Sample robot setting up The product has been developed for operation indoors and may not be used in explosive environments. Place the instrument in a location of the laboratory which is suitable for operation and provides protection against corrosive atmosphere and contamination by chemicals. The sample robot needs a horizontal and plane table that is stable and free of vibrations for a precise mode of operation. The work surface may not bend under a load of 60 kg. Observe the dimensions and weights of the individual products and modules that are part of the complete system. You will find this information in the "Technical specifications" section. Protect the product against excessive temperature fluctuations and direct sunlight. The power cord has to be accessible while operating and must not be replaced by an impermissible cable. 35

44 Replacing the seal of the sample beaker lid 5.3 Replacing the seal of the sample beaker lid The appropriate seals must be placed on sample beaker lids for KF titration (KF Dis-Cover lids) to tightly seal sample beakers. These seals must not be damaged. We recommend replacing the seal of the sample beaker lid approx. every 6 months. The standard seals were designed for aqueous applications and Karl Fischer titrations. If more aggressive solvents such as chlorobenzene or glacial acetic acid are used, we recommend using the sample beaker lids (Dis-Cover lids) without seals.
