    摘要: The present invention relates to a method of identifying in a fluid by measuring the amount of optical rotation the fluid causes in a beam of polarized light. The invention further provides for the use of an optional optically active marker in the fluids in order the impact the amount of rotation the fluid will cause. The invention provides a convenient and reliable means for identifying the fluid before, during and/or after the fluid's use.
