Surface Coating / Alfa Chemistry

Surface Analysis Services


Surface and structural material studies can help researchers better understand the microstructure of a coating. Chemical composition, manufacture, and processing procedures all have an impact on the coating's microstructure and surface properties. These features will have an impact on the chemical, physical, and mechanical properties, as well as the function and performance of the product in the intended application or formulation.

Surface and structural material

Alfa Chemistry scientists are experts in surface analysis, which includes a variety of factors that influence surface chemistry and other surface-specific properties. When surface data is required, we will select the most appropriate analytic approach to provide the best results. Surface coverage, molecule orientation, functionalization, contamination, and surface separation are all investigated and understood in our lab using various surface analysis and surface characterization techniques. We help you examine contaminants, stains, and changes on items and equipment with our surface analysis service.

Our Strength

Alfa Chemistry's expertise in surface analysis can help you gain a deep understanding of the microscopic characteristics and microstructures of your goods and samples down to the nanometer scale.

Adhesion and Bonding

Adhesion is the process of uniting two or more surfaces. Contaminants in or on the connection surface can cause failure in polymer encapsulation, surface pretreatment, and organic coating. Failures are possible if adhesives are employed. Impurities, oxide layers, or buried contaminants may diffuse to the adhesion surface during or after bonding, resulting in the metallic lead failure in microelectronics.

In a surface analysis laboratory examination, determining the root cause of adhesion and adhesion difficulties may necessitate the employment of surface-sensitive analysis techniques.


Depending on the surface and substance of interest, evaluating surface cleanliness may require a variety of measurement methodologies. The discrepancies between the test sample and the control or reference sample are usually best highlighted using this method.

Understanding the potential sources of pollutants is frequently required when assessing cleanliness. Techniques with detection limits in the parts per million range, such as total reflection X-ray fluorescence (TXRF), which only detects elemental species, or time-of-flight secondary ion mass spectrometry (TOF)-SIMS, may be required for studying highly clean surfaces. Scanning electron microscopy (SEM) may be an excellent choice if cleanliness is determined by the number of particles on the surface.

Morphology and Topography

Imaging techniques like optical microscopy or scanning electron microscopy are the greatest ways to assess morphology or "sample appearance" (SEM). These approaches can also provide quantitative information such as layer thickness.

To resolve the topography, multiple measures of roughness, step height, size, and feature size can be taken using an atomic force microscope (AFM), optical profilometry (OP), or stylus profilometry.
