WebThe ATS salt spray testing lab houses several chambers capable of performing accelerated corrosion exposures to a multitude of industry standards, such as ASTM B117, ASTM … WebJun 1, 2024 · In one study, high salt concentration in wash buffer (i.e., 1.5–2.5 M) has been shown to compromise step yield and monomer purity in the eluate [16]. Thus, the salt should not be added to a concentration more than necessary. However, the adequate amount of salt required for effective HCP clearance is less consistent in literature.
