Portable Spark Spectrometer

ESAPORT is the GNR portable optical emission spectrometer with a large analytical flexibility.

E3 Esaport

E3 ESAPORT portable optical emission spectrometer for analysis on site, equipped with arc and/or spark excitation source, is the perfect instrument for all fields of applications in Metal Sorting, positive Material Identification (PMI), incoming quality controls and so on.

Using the argon gas flushed pistol the results are comparable with the ones obtained with a Lab instrument, according to sample‚Äôs preparation. 

The instrument is extremely functional and allows the rapid identification of all metal alloys and the analysis of elements such as C, Al, Si and Mg.

It is, for this reason, competitive to the portable X ray portable systems, because it has a bigger analytical capacity and is not submitted to restrictions related to radiogenic sources detection. 

The instrument is small sized and can be brought and used everywhere, from production department to warehouse. In addition a practical and handy trolley (optional) is available to make easier the movement from a place to an other. 

  • Dedicated CCD Optical System 
  • User-Friendly Panel PC 
  • Special Power Management with battery (optional) for independent running 
  • Trolley (optional)
  • On Site Analysis 
  • Metal Sorting 
  • Positive Material Identification (PMI)
