Low detection limits down to 10 ng. Low
evaporation temperatures and outstanding reproducibility. No baseline
shift even with extreme gradients. The fully warranted Teflon nebulizer
provides superior solvent and chemical resistance, eliminates sample
build-up even at high temperatures, does not permit sample carry over
or increased noise from surface leaching. Reproducible droplet
distributions are assured by thermally isolating the nebulizer from the
spray chamber and drift tube, improving reproducibility between methods.
Low gas pressure and flow requirements allows use of cylinder, house systems, or gas generators. The pneumatic system is protected by a high pressure shut off, and provides a signal in the event of unstable or low pressure.
