The module also contains a flow control valve to automate filling, rinsing, and dispensing functions within an instrument. Each module is operated through a shared communication bus protocol, enabling multiple modules to be operated simultaneously from a single controller.A flow validation study conducted by IDEX Health & Science proved an existing need for CDM technology, verifying significant variation in flow rate precision systemic among mechanically driven pumps commonly installed in scientific instruments. The study found that the design of precise pump technology requires compensation for system compression, errors in the pump mechanism, and temperature effects on the system fluid paths.Constant Flow FeedbackThe flow sensor integrated into the CDM provides feedback to the pump. Using this flow feedback, the pump dynamically adjusts flow output to a user defined set point ten times per second. This continuous flow monitoring allows for very consistent flow, even under conditions of changing pressure produced by downstream devices, trapped gases, system compression, or variations in the pump mechanism. The result is higher precision fluid handling that creates more accurate data and higher customer confidence in the analysis. Component ModularityThe CDM can be reconfigured to fit an OEM’s existing instrument fluid path. IDEX Health & Science can also co-engineer the entire fluid path of a future generation instrument from schematic to assembly, expanding an OEM’s engineering capacity and speeding instrument development. With more than 100 fluidic engineers, IDEX Health & Science is fully equipped to be the single development or manufacturing resource for fluidic system integration.The CDM’s ability to integrate “Flow Feedback” dramatically improves stability, precision and rise time during flow rate changes.Time (s)Flow rate (nL/min.)20040006000 200800400Feedback offFeedback onIDEX Health & Science LLCwww.idex-hs.comNorth/South America +1 866 339 4653 I Europe +49 1801 808 800 I Asia +86 10 6566 9090Specification Description Details UnitsPump head options100 µL Titanium N/A250 µL Titanium N/A1125 µL Ultem® N/A5000 µL Ultem N/AFlow feedback range* Forward and reverse flows -50,000 to +50,000 nL/minFeedback flow rate precisionPercent of set point 0.1% or better** RSDFlow rate accuracy Flow sensor calibration dependent Less than or equal to 3% percentOpen loop flow range* Forward flows Up To 150 mL/minOpen loop flow rate precision Percent of set point 2% RSDOpen loop flow rate accuracyNo feedback control Less than or equal to 5% percentPressure range Dependent on components selected 0-345 barWetted materials optionsPEEK™, stainless steel, zirconia, fused-silica, Perlast®, and UHMWPE, Viton®, EPDM, etc.Acetonitrile, water, methanol, ethanol, propanol, TFA, acetic acid, formic acid, etc.N/AAutomated control RS-232/other options yes N/APressure feedback Offered on 100 µL and 250 µL pump head options0-345(0-5000)bar(psi)Pump encoder feedback Optional - N/APump seal wash Optional - N/ASize D x W x H, (depends on OEM configuration) 25.4 x 5.72 x 20.3 cmWeight Dependent on OEM design 1.42 kgPower Peak power 24VDC, 2A N/AGeneral SpecificationsCDM Module SpecificationsThe CDM is designed to meet the following specifications:Note: Custom configurations available.
