SECcurity Detectors 



SECcurity column compartment 80°/100°
  SECcurity GPC1200 Refractive Index RI detector  
Part number: 404-0006 
The detector of  choice for the anaylsis of non-UV absorbing samples. Ideal concentration detector for the combination with on-line light scatterging detectors or on-line viscometers. High signal-to-noise ratio is enabled by a minimum baseline noise. Electronic temperature regulation maintains a steady optical unit temperature up to 55° C. Convenient early maintenance feedback (EMF) is available. An automatic solvent recycle valve is already included.

SECcurity ELS Detector
  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
