Synthesis of artificial diamonds requires Raman spectroscopy research. The Raman imaging helps ascertain the quantity of diamantine in fine-dispersed carbonic mass (explosion method).
2D Raman image of seemingly homogeneous carbonic powder indicates the presence of diamantine in it.



Graphene Raman investigation

(one of the most popular modern physical research task)

The Nobel Prize in Physics 2010 was awarded “for groundbreaking experiments regarding the two-dimensional material graphene”.



Graphene mapping *


Raman imaging of a surface (made with a 1 μm step) allows determination of thickness of carbonic coatings, and thus enables detection of tiny graphene flakes of several μm in size only.



* Automatic 2D imaging complex can be ordered optionally

Experimental results of graphene synthesis


  1. Diamond-like films deposited with ions of different energies, which effect on the surface. 
  2. Mechanical exfoliation graphene. 
  3. A film of nanocrystalline graphite deposited by ECVD.



RAMOS W532 Ultimate solution for analysis of undefined compounds 




  • Trace forensic analysis of fibers, hair, pigments, ink, fabrics etc.
  • Trace analysis of illicit substances
  • Identification of explosives and their precursors
  • Qualitative analysis of liquid explosives in micro doses

Motorized sample stage with a 0,36 μm step allows distinguishing particles of 1 micron in size among thousands of others with different chemical and physical properties.



Mix Splitter Complex for Qualitative and Quantitative Analysis of Heterogeneous Powders


Mix Splitter Complex is an add-on solution to RAMOS W532 Raman Microscope. 
Mix Splitter technology analyses each grain of the mixture which improves the limit of detection of residual contaminant (detects pieces of 10 μm size) and ensures more accurate identification of components concentration – below 1%.



Detection Limit


  • 0,5% within 15 minutes
  • 0,1% within 80 minutes

Error depending on impurity concentration


   0.1-0.5% of impurity     Error < 50% 
 >5% of impurity

Error < 5%
