  • Tales from the M&P Lab

    by Emily Walsh July 2017

    In the BTG Labs’ Materials and Processing laboratory, magic happens. Or, at least it seems that way. In the BTG Lab our specialists see the unseen. They reveal the invisible.

    We’re talking about invisible surface chemistry, of course.

    “Usually, the customer knows there’s something wrong with the surface, but they don’t know what,” says M&P Engineer and R&D Chemist Brooke Campbell. She and Elizabeth Kidd, our R&D Chemist and custom application scientist combine their analytical expertise with the instruments in our highly sophisticated lab; they evaluate, characterize, and optimize critical surface processes for industries from consumer goods, medical device, aerospace, and everything in between.

    Using highly advanced instruments such as the XPS (X-ray Photoelectron Spectroscopy), FTIR (Fourier Transform Infrared Spectroscopy), Instron, goniometer, and of course, the Surface Analyst, the lab performed various tests to evaluate the surface. They then characterize the issue. This usually entails identifying a contamination or an issue with surface preparation. Lastly, they deduce an answer.

    In some instances, Brooke explains, the customer has implemented an instrument in their manufacturing processes. All is well until they come across a batch that is out of spec. They know there isn’t a problem with the instrument, but that’s it. So, their puzzle makes its way to the M&P lab for investigation. …Read More

  • SAMPE is the “Society of Advancement of Materials and Process Engineering,” and annually they host a conference and exhibit hall where Scientists and Engineers gather to learn about the past year’s manufacturing advancements. Giles Dillingham, our Chief Scientist and CEO, has been a member for 15 years, and BTG Labs has presented many different technical papers and research projects at this conference. This was my second time attending this conference, after last year in Long Beach.

    While SAMPE targets the advancement of all materials and processes, composites—namely carbon fiber—dominate the show. Many exhibitors manufacture woven carbon fiber materials that will be turned into aircraft structures or interiors. Other vendors supply OEM aircraft manufacturers and tier 1 suppliers, specific parts that will be installed directly onto final products.

    Some examples include specialized composite tubing and fluid tanks for waste and water storage. I also saw: tooling manufacturers, adhesive and tape suppliers, software companies, testing labs, autoclave/oven vendors (one was giving virtual reality tours of their equipment!), and material processing equipment. This included 4 plasma treatment companies. The most we have seen at SAMPE to date. …Read More


    BTG Labs is proud to have the Surface Analyst featured on the cover of the January/February issue of SAMPE Journal (Society for the Advancement of Material and Process Engineering). The journal includes the latest in the field of materials and processing.

    As a company with a state-of-the-art Materials and Processing Lab, BTG Labs has regularly been presenting and attending SAMPE conferences and events for 10 years. Subscribe to the SAMPE Journal to read this month’s issue on adhesives and bonding featuring articles such as “Quality Controlled Induction Welding by Adapted Process Parameters.” …Read More
