2 Stationary Phases In Gc Can Be Connected To The Column Walls Or To Solid Support Particles Through A Covalent Linkage 1 (101.9 KiB) Viewed 34 times
2. Stationary phases in GC can be connected to the column walls or to solid support particles through a covalent linkage. Here are some common stationary phases: H2C HEC CH3 CH3 CH3 CH3 to Н.С. Si O si Si O CH3 (CH2)3 wter to H3C m4 Jn CH3 CN a. Why do analytes interact with these polymers? List at least two specific IMFs. b. The first polymer shown is called poly(dimethyl siloxane) or PDMS. i. What IMFs are available with this stationary phase?
ii. Why would an analyte stop interacting with this stationary phase? iii. What could you do to get your analyte to stop interacting with this stationary phase?
