Frequently Asked Questions:
What is the NVPC in pharma?
Answer: NVPC stands for Non-Viable Particle Count in the pharmaceutical industry. It refers to the measurement and monitoring of the concentration of non-living or inanimate particles present in the air within a controlled environment.
What is non viable particle monitoring?
Answer: ( NVPC ) Non-viable particle monitoring involves the continuous surveillance and analysis of airborne particles that do not possess the ability to grow, reproduce, or sustain life. These particles can include dust, fibers, lint, and other contaminants that may be present in the pharmaceutical manufacturing environment.
What is viable and non viable air monitoring?
Answer: Viable and ( NVPC ) non-viable air monitoring refers to the distinction between the measurement and monitoring of living particles (viable) and non-living particles (non-viable) in the air. Viable air monitoring focuses on the detection and enumeration of microorganisms such as bacteria and fungi, which have the potential to impact product quality, while non-viable air monitoring aims to identify and control non-living particles that may pose risks to product integrity and patient safety.
Why only 0.5 and 5 micron particle count required in pharma?
Answer: In the pharmaceutical industry, particle counts are typically performed at specific particle size ranges, such as 0.5 microns and 5 microns.
