Scanning electron microscopy sees surface structure and elements

Processes are often warm and humid that create good environments for bacteria, precipitates and other undesirable phenomena that contribute to disruption and degradation of end products. Scanning electron microscopy (SEM/XDS) has a wide range of applications; studies of cross-sections and surfaces of finished product, stains and impurities.


To be able to identify and check smudges, stains, deposits, you can turn to us. We can analyze many sample types, mainly pulp, paper and cardboard but also scrap, dots, rubber cloth, printed end product, liquids, incrustations, metals.

Some examples of different types of assignments are surface studies, crystal structure, cross-sectional analyzes, filler distribution in cross-section, filler characterization but also amount of filler. Pigment coverage is also common as well as elemental composition. We also look at bees, coating warehouses where we can assess the number and composition.


SEM/EDX has:

  • Secondary detector, SEI, which shows surface structure / topography
    • Back scattering detector, BSE, which provides elemental contrast
    • Heavy elements (inorganic material) give light parts
    • Light elements (organic material) give dark areas
  • X-ray detector, EDX, which provides elemental composition
    • EDX = Energy Dispersive X-ray Analysis
    • Low vacuum, LV

The instrument provides grayscale images and magnifications up to 50,000x. The theoretical magnification limit is 300,000x, resolution 3 nm at 30 keV.



Recommendations for sampling:

Scrape in a jar when sampling

Do not mark too close to the defect / problem

Exposure is performed on RISE

Send references
- Process and functional chemicals / materials
- Good reference test to compare with problem / bad test

    Delivery time

    Analysis results are delivered by e-mail, normally within 15 working days of the samples arriving to us. With reservation for samples that require special treatment. Express analyzes can be obtained at a surcharge by agreement.

    If nothing specifically agreed, the samples are saved four weeks after analysis.
