This special liquid scintillator is formulated specifically
for encapsulation in capillaries with bore size down to
250µm (1/100") for imaging with fast neutrons.
Its important properties are,
|
- Very high light output
- High refractive index
- High flash point
|
- Low chemical toxicity
- Biodegradable
|

For good light-piping in capillaries, high refractive index
is critical.
Among the several liquid scintillator solvents traditionally
known for their high refractive indices, most are chemically
and photochemically unstable and consequently darken over a
period of a few months if exposed to air or UV light for even
relatively short times.
Hence the components of EJ-399-05C1 were selected to provide
an outstanding combination of high scintillation efficiency,
high refractive index and excellent chemical stability in order
to endure the often complicated handling associated with
encapsulating liquids in capillary arrays.

EJ-399-05C1 additionally has a low vapor pressure making it
suitable for using vacuum techniques when loading capillaries.
Its high flash point and low chemical toxicity make it a
relatively safe liquid to handle.
It is always advisable, however, to exercise reasonable caution
when handling organic solvents with regard to personal contact
and breathing.
