40°C for 4 min to 60°C at 5°C/min to 150 °C at 25°C/min for 2 min
Carrier Gas:
Constant Flow Helium, 1.5 mL/min
Detection:
Mass Selective (MSD) @ 18-400 amu
Sample Notes:
Ethanol at 0.5% concentration was used as the internal standard. RSD values for water were calculated at 1.8% with n = 3. Detector was turned off for isopropanol solvent peak at 3.3 min to 4.0 min to prevent detector overloading.
