WebMay 2, 2024 · Light obscuration testing is the preferred method of sub-visible particle quantification but is not suitable for every preparation. Green Wind - stock.adobe.com Particulate matter by light obscuration (LO) testing quantifies particles in suspension by their projected shadow onto a photo sensor. WebFor the determination of particulate matter, two procedures, Method 1 (Light Obscuration Particle Count Test) and Method 2 (Microscopic Particle Count Test), are specified hereinafter. When examining injections and parenteral infusions for sub-visible particles Method 1 is preferably applied. However, it may be necessary to test some preparations
