What NSL Analytical Services does

NSL Analytical Services, Inc. is an independent ISO/IEC 17025-accredited analytical and metallurgical testing laboratory founded in 1945 and headquartered in Cleveland, Ohio. The company provides third-party chemical composition analysis, mechanical testing, metallography, powder characterization, and material qualification services to over 1,700 customers across highly regulated industries including aerospace, defense, medical devices, nuclear power, additive manufacturing, EV battery materials, mining, and ophthalmic. Core technology comprises a broad instrumentation portfolio including ICP-MS and ICP-OES (NSL was the first commercial lab to deploy ICP-MS, in 1994), XRF, XRD, LECO combustion analysis, GC-MS, LC-MS/MS, SEM with EDS, Karl Fischer titration, and a suite of mechanical test frames for tensile, impact, hardness, creep, and stress-rupture testing; the laboratory operates additional Cleveland facilities and added a Pleasant View, Utah operation through the December 2025 acquisition of Rocky Mountain Testing Solutions (RMTS). The business is structured as professional services billed per testing project, with revenue generated through direct enterprise sales driven by website quote requests, phone inquiries, content marketing, and presence at industry conferences (AMUG, ASTM ICAM, Vision Expo). Since July 2024, NSL has been owned by Levine Leichtman Capital Partners (LLCP), which acquired the company from prior sponsor May River Capital and is executing a platform expansion strategy combining organic vertical build-out with tuck-in M&A.
