The Surface Analyst™ is an innovative handheld solution for use in the lab and on the factory floor. It reduces waste, rework, and recalls when poorly prepared substrate surfaces lead to bonding, coating, sealing, painting, or printing failure.
Using contact angle measurement, the Surface Analyst measures the cleanliness level of surfaces and determines how ready it is to accept the adhesive, coating, print, or paint. Developed and manufactured by Brighton Science, it is a fast, easy, accurate, and non-destructive tool for manufacturers with critical surface requirements. The Surface Analyst replaces legacy methods such as dyne and water break tests.

The Surface Analyst deposits a highly purified drop of water on the surface. In two seconds, it measures the contact angle and, in turn, determines the cleanliness level of a substrate.
When a surface is clean, it emits high energy, and water--as a high-energy molecule--spreads out on the surface in attraction to other high-energy molecules (Figure 1). A contaminated surface emits low energy and will cause water to bead up in attraction to itself rather than the low-energy surface molecules (Figure 2).
By knowing the volume and area of a drop of water, the contact angle of the water against a given surface can be determined. The larger the contact angle, the more the water beads up on the surface – and, therefore, the lower the energy level of the surface.
When adhering, the surface requires a level of cleanliness in order to produce strong, reliable bonds. Ensuring surface condition and consistency is vital for guaranteeing success in sealing, coating, bonding, painting, printing, or cleaning. All surfaces contaminate upon exposure, and the presence of contaminants is inevitable. However, studying and comprehending the relationship between a contaminant structure and the effects it can have on a bond can help develop more productive monitoring procedures for surface preparation processes and can also impact the development of stronger adhesives and coating formulations.
Outdated evaluation methods such as dyne and water break are destructive and do not provide reliable, precise, quantifiable surface measurements. The Surface Analyst exemplifies these traits on the factory floor in seconds.
