MINERAL OIL BASED WITH PSD
EJ-325A is a mineral oil based liquid scintillator having pulse shape discrimination (PSD) properties for the separation of fast neutrons and gammas. EJ-325A replaces the original EJ-325. The new formula exhibits slightly improved scintillation efficiency and PSD properties and, importantly, has a very high flash point for safety and ease of shipping. With the mineral oil as a major solvent component, EJ-235A possesses greater optical clarity for use in large tanks.
EJ-325A exhibits considerably low solvent properties making it ideal for incorporation in containers fabricated with cast acrylic and PVC.
