•
Pyrethroids analysis
–
Late-elutingpyrethroids can be difficult tokeepwell resolved
on standard columns due to limitedmaximumoperating
temperature.
–
Peakwidth is narrower if the compounds are elutedduring the
temperature program, not on an isothermal hold
• Preference is for columnwithhighmaximumoperating temperature
–
Selectivitymust be appropriate to achieve separationbetween
the target compoundswhich can have similarmass spectra
