Control Standards and Method Recommendations for the LS 13 320 XR
Abstract
The LS 13 320 XR particle size analyzer features a significantly improved particle analysis range that spans from 10nm to 3500µm. The improved electronics and optical detection system extends the analysis range providing actual measurement capability from 10nm to 3500µm while improving individual peak discrimination. With this new capability come a new set of control standards to adequately verify instrument/module performance. Periodical performance checks in the lab provides the customer confidence that their measurement system is operating at peak performance levels.
Introduction
The following tables detail the important Control Standards and Method setup. The new ADAPT software allows easy Method creation to include specific and critical parameters located in the table below. Periodic quality checks will prove equipment capability and will inspire confidence in the instrument and can satisfy Quality department requirements and concerns.
