Hopefully someone on here can help me...I have a lab report due that deals with gas chromatograph, we made our own using a glass column and filling itwith Tide detergent, we attatched one end to a natural gas burner and the other end is attached to another piece of glass with a copper coil on the end. We injected different gases with a hypodermic needle and then calculated the flow rate. How does the flow rate change for the different gases? Is it due to pressure or polarity? Or am I really off the scale..any input would be greatly appreciated!! THANKS
