Working with solutions containing decachlorobiphenyl
Decachlorobiphenyl has poor solubility in most organic solvents.
The maximum concentration that can be prepared in acetone,
hexane, or isooctane is 200 µg/mL. Temperature will affect the solu-
bility as well. Storing solutions at reduced temperatures will cause
decachlorobiphenyl to precipitate.
Products containing decachlorobiphenyl must be sonicated for a
minimum of 10 minutes prior to opening the ampul. Because each
ultrasonic bath operates at a different energy level, 10 minutes is
a guideline only. Longer sonication time will not affect product
quality.
These precautions apply to working solutions prepared in your
laboratory as well. The amount of compound that precipitates
depends on concentration AND temperature. If you store your
standards at a temperature lower than 4 °C (even dilute solutions),
allow extra sonication time.
