Speeding up the Application
using HYDROGEN Carrier Gas
• Using hydrogen we can operate at near 2 times the
linear velocity as used for helium
• This results in significant shorter run time
• To get the same chromatogram/separation, we need to
adjust the oven temperature program
Fast DHA Analysis using Hydrogen…
Analysis time < 80
minutes..
Fast DHA using Hydrogen
• Same GC
• Same method
• Same Injection/detection techniques
• Same column
• No issues with overloading, peak shifts, tailing, high inlet
pressures, discrimination and reduced life time..
All retention data and identification is generated by Neil Johansen, developer of the
D6730 DHA method.
