Abstract: In one aspect, the disclosure provides a method of defining a Raman signature of a culture component, the method comprising: obtaining a Raman spectrum of a culture component in a non-interfering or minimally-interfering solution, identifying peaks in the Raman spectrum that are associated with the culture component, obtaining a Raman spectrum of a culture medium comprising the culture component, and, removing peaks of the culture component in the Raman spectrum of the culture medium that are distorted compared to the peaks identified in the Raman spectrum of the culture component in a non-interfering or minimally-interfering solution.
