This term denotes the likelihood of precisely detecting and enumerating particles within a specified size spectrum. In this context, the term "counting efficiency" represents the ability of the particle counter to quantify particles of a given size accurately. It measures the instrument's performance, indicating how effectively it can detect and count particles of various sizes.

We will study each critical area of the fill line and the activities necessary to effectively bring the control features into effect. These examples come from real-world applications experienced by the Particle Measuring Systems’ Advisory Services Team. Our team has over 70 years of collective experience working in and advising cleanroom users around the world.
