Troubleshooting for Liquid Particle Counting

Abstract

This paper discusses how to ensure that a liquid optical particle counter (OPC) is producing valid data.

Ensuring that your liquid OPC is operating within its designed specification is critical to obtaining quality data. As data from OPCs becomes increasingly important to maintaining process control, it becomes more critical than ever for operators to have confidence in the data being generated. OPC data is frequently used to qualify process improvements, control chemical manufacturing, and maintain quality control for production of complex parts. It is common for operators to wonder if the OPC is working correctly when the data collected does not match their expectations. Common misunderstandings and performance issues about OPCs are discussed to help the operator reach proper conclusions when questions arise about the validity of the data.
