Clarus Gas Chromatographs - Clarus 680/580/480

Significance of the Topic

Gas chromatography is a foundational analytical method that offers high resolution, sensitivity and reproducibility for the separation of volatile and semi-volatile compounds. It is critical for environmental monitoring, food safety, petrochemical analysis, forensics and quality control in industrial and academic laboratories.

Objectives and Overview

This document presents the PerkinElmer Clarus® gas chromatograph family, highlighting design innovations, operational flexibility and application-specific configurations of the Clarus 680, 580 and 480 models and associated accessories to meet diverse analytical and throughput requirements.

Methodology and Instrumentation

The Clarus GC series integrates advanced oven technology, programmable pneumatic control and modular injectors and detectors to streamline complex analyses:

• Twin-walled conventional oven with concentric exhaust for rapid heat-up and cool-down, enabling injection-to-injection times under two minutes
• Programmable pneumatic control (PPC) for stable carrier-gas flow under varying ambient conditions
• Swafer™ micro-channel flow module for automated detector switching and multidimensional separations
• Integrated 108-vial liquid autosampler with optical monitoring for high-throughput, reproducible injections
• Detectors: FID, TCD, ECD, NPD and quadrupole mass spectrometer (SQ 8 GC/MS) with 1–1200 amu range and high scan speeds
• TurboMatrix™ headspace, headspace trap and thermal-desorption systems for volatile analysis
• Empower® 3 chromatography data system for unified instrument control, data processing and 21 CFR Part 11 compliance

Used Instrumentation

• Clarus® 680, 580 and 480 Gas Chromatographs
• TurboMatrix™ Headspace and Headspace Trap
• TurboMatrix™ Thermal Desorbers (ATD 650 series)
• Swafer™ micro-channel flow technology
