5. 5 What is TurboFlow?  Chromatographic technique On-line sample extraction plus chromatographic separation Exploits difference between large and small molecules Incorporates column chemistry  Large particle columns (30 µm or larger)  High flow rate, low back pressure  Efficient mass transfer created by turbulence  Separates low MW analytes from high MW matrix  Allows for the direct injection of biological fluids Eliminates sample prep (SPE, protein precipitation, liq/liq extraction etc) Cleaner extracts, less source maintenance Fast analysis

6. 6 Turbulent Flow With Turbulence Without Turbulence High linear velocities with large particles create turbulence

7. 7 Molecules Interact with the Stationary Phase  Column particle contains small pores  Fluid inside pore is nearly stagnant

8. 8 Small molecules diffuse into pores faster than large molecules Small and Large Molecules Diffuse at Different Rates

9. 9 Large Molecules Flow to Waste  Large molecules do not have time to diffuse into pores  They are flushed through the column by the high-velocity mobile phase  Sample residence = 300 milliseconds Particle Pore

10. 10 Column Chemistry  Small molecules that have diffused into pores either bind to selected column chemistry or exit the column Particle Pore

11. 11 Small Molecules are Eluted A change in mobile phase composition elutes compounds of interest to the detector or to an analytical column Particle Pore
