EJ-301 exhibits excellent pulse shape discrimination (PSD) properties, particularly for fast neutron counting and spectrometry in the presence of gamma radiation. It is identical to the widely reported NE-213 and exhibits all of the properties of that scintillator.

EJ-309 has been developed as an alternate to the more commonly used low-flash point PSD liquid scintillators based on the solvent xylene. With a flash point of 144°C, it eliminates the fire hazard associated with low-flash point liquid scintillators. While EJ-309 provides slightly poorer PSD characteristics than that of EJ-301, EJ-309 possesses a number of chemical properties recommending it for use in environmentally difficult conditions. These properties include: high flash point, low vapor pressure, low chemical toxicity, and compatibility with cast acrylic plastics. EJ-309 is also available loaded with natural boron as EJ-309B.
