The history of BTG Labs is rooted in adhesion research. Originally a development lab, BTG Labs specialized in plasma polymerized coatings. The engineers worked with coatings containing corrosion resistant and anti-microbial properties. BTG Labs worked to improve adhesives and surface treatment processes. This brought about the Surface Analyst and today, BTG Labs still utilizes its twenty plus years of Materials Science expertise to assist manufacturers in understanding how the Surface Analyst fits into their production process and how their surfaces affect the overall manufacturing processes.
As an innovative and investigative materials science company, BTG Labs boasts a highly sophisticated lab with several analytical instruments. BTG Labs not only produces the ideal surface measurement device, but it can help develop surface preparation processes, trouble shoot existing surface sensitive processes, and diagnose surface chemistries.
Knowing Your Surface
Surface chemistry directly relates to surface energy and can predict a surface’s ability to maintain a bond. Thus, when developing or remodeling surface processes, knowing the chemistry of one’s surface is a good starting point. Our X-ray Photoelectron Spectrometer (XPS) uses X-Rays in an ultra-high vacuum system to provide elemental information of specific surface chemistry. Sensitive to the top two molecular layers of a surface, the XPS reveals to the customer exactly what is on the surface of their product.
The Fourier Transform Infrared Spectroscopy (FTIR), another powerful technique utilized for surface analysis, uses infrared light to detect the presence of functional groups on the surface of your material. It is also capable of coating characterization (i.e. liquid films, contaminant residue, coupling agents etc.). With specular reflectance, attenuated total reflectance (ATR), transmission, and diffuse reflectance accessories, BTG Labs is equipped to analyze a vast array of materials and surfaces.
A Surface Preparation Guide
In preparation of the American Medical Device Summit, October 5-6 2016, BTG Labs and Generis have created an eBook, “Surface Preparation for Medical Device Manufacturers.” With over 175 companies involved, this summit is a chance for those in the industry to connect and exchange ideas.
This eBook discusses the critical surface requirements in the medical device manufacturing field for sealing, coating, painting, printing, bonding, and cleaning. The industry uses vacuum plasma, atmospheric pressure plasma, and corona treatment for polymer bonding. Yet, there has been no quantifiable way to verify the cleanliness of their surfaces. Surface cleanliness verification is crucial in medical device manufacturing as it can speed production, ensure production safety, and reduce the likelihood of recalls.
