Moving from System II to Metrohm NIR Systems Analyzers

Importance of the Topic

Near-infrared spectroscopy (NIR) is a fast, non-invasive technique widely used in quality control, process monitoring, and research across industries such as pharmaceuticals, food, agriculture, and chemicals. Upgrading legacy analyzers enhances analytical performance, operational efficiency, and data reliability in both laboratory and process environments.

Objectives and Overview of the Article

This document outlines the transition from System II analyzers to Metrohm NIRSystems XDS and DS2500 models, highlighting new features, performance improvements, and the workflow for model transfer and implementation.

Methodology and Instrumentation

Key upgrades include a high-output lamp module with patented reflector for improved signal intensity, an off-axis digital synchronous holographic grating for finer spectral resolution and four times more data points, and a sealed enclosure with internal standards for automatic calibration of wavelength accuracy and photometric response. Enhanced electronics, hot-swappable modules, and Ethernet communication further streamline operation.
