SECcurity Evaporative light scattering detector ELS4000 Part number: 409-0025 ELSD with superior and sensitive detection for a wide variety of chemical classes and structures. With ThermoSplit technology for the optimal signal to noise ratio. 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. Specifications Detector type:  Evaporative light scattering detector with Thermo-Split Evaporative Zone Temperature:  25° C - 120° C Thermo-Split™ Chamber Temperature:  10° C - 70° C Light source 670 nm laser diode, <5 mW Flow rate:  0.2ml/min to 5ml/min Detection limit:  10 ng Gas requirements:  4 - 5,5 bar (60-80psi) nitrogen or other inert gas Analog output:  0 - 5 VDC
