Diluent:Acetonitrile
InjectionPTV splitless (hold 0.35 min)
Liner:PTV on-column liner (cat.# 24976)
Inlet Temp. Program:55 °C to 285 °C at 10 °C/min (hold 10 min)
PTV Splitless
Purge Flow:15 mL/min
Oven
Oven Temp.:50 °C to 280 °C at 10 °C/min (hold 10 min)
Carrier GasHe, constant flow
Linear Velocity:60 cm/sec @ 300 °C
Detectorµ-ECD @ 300 °C
Make-up Gas Flow Rate:60 mL/min
Make-up Gas Type:N2
NotesAbsolute area reproducibility improves for all compounds, and sensitive compound responses improve dramatically because of the lack of contact with the injection port.

Nitroglycerin: Absolute Area % RSD = 2.6%; Relative Area % RSD = 1.6%
TNT: Absolute Area % RSD = 1.5%; Relative Area % RSD = 1.4%
