  3. Microscale Fluid Handling System • A solution for conducting microscale reactions (digestion, separation etc.) and for efficiently transporting microliter to picoliter samples from a chip to an analytical device and/or a collection device. • Advantages • Efficient Sample Transport • Reduces manipulations (e.g.. flushing) • Reduces/eliminates problems of sample carryover • Savings • Less Sample, Reagent(s), Time

  4. Microscale Fluid Handling System • The System • Multiple sample introduction methods • Pressure, electrokinetic Injection • Single or multiple channel(s) & channel designs • Parallel, circular/ cylindrical, trapezoidal • Multiple sample transfer methods • Droplet, spray, or stream • Multiple analytical or collection devices • ESI, MALDI, NMR, Fraction Collector, Chip, Multi-well Plate • Sample either liquid or gas • License non-exclusively - Currently 5 licensees

  5. Sample Loading and Injection Device • A solution for a universal interface device for transferring samples in series or parallel from sample container (e.g. multi-well plates) into channels of a multi-channel microfluidic device and/or into an analytical device that can be integrated into or separated from a microchip. • Advantages • Uses standardized sample plates • Variable sample volumes • Reusable or disposable device

  6. Sample Loading and Injection Device • The System • Sample introduction • Pressure, Electrokinetic, Vacuum, etc. • Sample trapped/digested inside loading channels • High hydrodynamic resistance • Sample Elution • Micro, analytical, and/or collection Device • Sample separation (optional) • Electrical potential, etc • License exclusively or non-exclusively

  7. Microchip Integrated Open-Channel Electro-osmotic Pumping System • A solution to control fluid dynamics in microfluidic device by using pump(s) to generate electro-osmotic flow or pressurized flow in the device and/or to perform sample transfer, gradient generation or fraction collection/deposition. • Advantages • Easily integrated into existing microchips • Its fabrication ensures high manufacturing and operating reproducibility • Simple design

  8. Microchip Integrated Open-Channel Electro-osmotic Pumping System • The System • Single or multiplexed pumps • The voltage drop for operation of the electro-osmotic micro pump may vary from a few tens to thousands of voltsdepending on the length of the pumping channels and desired flow rate and pressure. • License Exclusively or Non-exclusively

  9. Electro-pneumatic Distributor for Multiplexed Myu-Tas Devices • The purpose of the distributor is to supply simultaneous electric current and pressurized gas to control individual channels of a microchip system in an assembly to use with electrospray mass spectrometry. • Advantages • Maximizes sample throughput for analyzing samples • Decreases time between sample analysis • Eliminates need for flushing of sample • Eliminates need for washing sample probe • Fast switching times • Eliminates/ reduces cross contamination • Decreases the number of runs • Well plate samples can be used for further studies

  10. Electro-pneumatic Distributor for Multiplexed Myu-Tas Devices • The System • The distributor contains a gas channel and an electric conductor, which supplies an electric current and pressurized gas to the system. • The electrical current forces the sample to flow in a uniform direction, which controls sample flow dynamics. • The pressure created in the system controls fluid dynamics in electric field free regions. • Each sample container/well is connected by an independent microchannel distributor to separate electrospray tip. • License exclusively or non-exclusively

  11. Small Volume Transport • A solution for moving small volumes of sample through the capillary channels or tubing of a microfluidic device, especially long distances. • Advantages • Minimal loss or dilution of sample. • Minimal cross contamination between samples • Minimal loss of sample to channel walls • Washes inserted between samples • Faster sample changes • Multiple sample plugs injected at closely spaced intervals • Samples can be transported long distances with high speed to devices, such as an NMR.

  12. Small Volume Transport • The System • A sample/wash plug is formed between immiscible liquid plugs and immiscible liquid lining the transport channel walls. • System Characteristics • Immiscible carrier – e.g. fluorocarbon • Distances – yards • Channel walls - fluorine rich surface • Teflon (PTFE, ETFE, FEP, NGFP) • License exclusively or non-exclusively

  13. Subatmospheric,Variable Pressure Delivery Chamber • A solution for more efficient sample transfer from electrophoresis capillary or microchip to a mass spectrometer through an electrospray chamber by controlling pressure to allow fine control of sample flow rate from electrospray needle. • Advantages • Minimal sample loss • Lower evaporation of droplets • Efficient desolvation • Minimal power supply source needed

  14. Subatmospheric,Variable Pressure Delivery Chamber • The System • Ports for introducing gas into and withdrawing gas from the chamber. • Capillary tube(s) or microchip with a groove or channel extending into chamber to deliver samples. • Sample moves from the sample delivery device to an electrospray tip in the chamber. • Subatmospheric pressure directs the sample flow from the electrospray tip into an analytical/collective device • License exclusively or non-exclusively
