HVAC: Saying Goodbye to HCFC-22 (R-22) Refrigerant

November 5, 2020

On January 1, 2020, the phase-out and ban of R-22 and R142b refrigerants required the consumption of R-22 and R-142b refrigerants to be reduced by 99.5% below the U.S. baseline.

Fractures (Part 2)

July 16, 2019

In Part II we discuss how using our Scanning Electron Microscope (SEM/EDS) helps answer important questions as to how a steel part harvested from the tongue of a failed trailer hitch broke, and what was the cause?

Fractures (part 1)

January 9, 2019

Our Scanning Electron Microscope (SEM) is capable of 100,000X magnification, allowing a close-up look at material surfaces for defects, inclusions, and fracture characteristics. By using a SEM/EDS to study the surface of the fracture, the question of how the part broke - or the mode of fracture - can be answered. Was the part pulled apart, sheared, twisted or bent? Once this is established, a review of the history of the breakage or failure may assist in answering the questions: Why did it break? or What was the cause?
