During the criminаl аctivity sоme C-4 explоsive (аlsо known as RDX) was thrown down the elevator shaft. The air in the elevator shaft was analyzed by gas chromatography fitted with a 15.0m polydimethylsiloxane (PDMS) column with 5% phenyl groups. The oven temperature starts at 30°C and increases to 250°C during the chromatographic separation. The flow rate was 5.6mL/min of helium and the detector for the analysis was an electron capture detector. Table 2: Gas Chromatography Separation of explosives Compound Retention Time (min) w (min) Boiling Point (C) unretained 1.27 0.010 150 2,4,-DNT 4.01 0.020 284 TNT 4.49 0.025 240 RDX 4.95 0.028 234 A. (6 pts) To improve the resolution between the compounds, the flow rate was increased. However, this did not improve resolution. In terms of the van Deemter model of band broadening, why did increasing the flow rate not improve the resolution? B. (6 pts) Besides column stationary phase material, describe 1 way to modify the GC column to improve the resolution between the analytes and which components of the van Deemter equation are affected to achieve this better resolution. (only the first modification listed will be graded) Explain in 3-4 sentences.
