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. These size ranges are chosen based on their relevance to pharmaceutical manufacturing processes and their association with potential product contamination. Contaminants within these size ranges are considered critical due to their ability to potentially impact product quality and safety.

What is the limit of non-viable particle count?

Answer: The limit for non-viable particle count in pharmaceutical environments is determined based on regulatory guidelines, industry standards, and specific manufacturing requirements. These limits vary depending on factors such as the cleanroom classification, the type of pharmaceutical product being manufactured, and the intended use of the controlled environment.

Why do we use 0.3 micron filters?

Answer: 0.3 micron filters are commonly used in pharmaceutical manufacturing processes for air filtration and particle control. This particular filter size is selected due to its efficiency in capturing particles of various sizes, including both larger and smaller particles. The 0.3 micron filter size is often regarded as a challenge size, as it is near the most penetrating particle size for filters and is therefore considered a conservative measure for ensuring effective particle removal. Using 0.3 micron filters helps maintain the cleanliness and integrity of the manufacturing environment by reducing the presence of particles that may impact product quality.
