Light obscuration hiac
WebThe instructional chapter USP<1787> mentions MFI as a possible orthogonal technique for subvisible particle analysis in addition to light obscuration. Even though MFI is also a light-based technique, it is typically superior to light obscuration in the detection of particles with a refractive index close to that of the surrounding formulation. WebMar 12, 2014 · This study examined the impact of these formulation matrix parameters on the ability to size and count subvisible particles using a variety of analytical methods including two light obscuration (HIAC, Syringe) and …
