Ultra Low bleed septum is low in free-siloxanes making it ideal for soil analysis by EPA Method 5035. Siloxane peaks originating from the silicone septa during in-vial heated purge and trap procedures like EPA Method 5035 can cause interference with detecting target analytes of similar retention times. Thermo Scientific ultra low bleed septa are low in free-siloxanes, radically reducing siloxane peak interference.
