Introduction to the Agilent Micro GC System
This manual provides comprehensive guidance for the operation of the Agilent P200 and P200H Micro Gas Chromatographs (GCs). These advanced, self-contained, and miniaturized GCs are engineered for rapid and precise gas analysis. They are designed to work seamlessly with the powerful Windows™-based EZChrom 200 software, which handles data management and instrument control, offering a complete and user-friendly gas analysis solution.
The Micro GC system enables high-speed gas analysis directly in the field. Each unit is equipped with one or two GC modules, an integrated carrier gas cylinder, and a rechargeable battery pack, ensuring portability and convenience.
The P200 model is optimized for analyzing gases with boiling points up to 150°C at ambient temperature. The P200H model extends this capability by analyzing heated samples (up to 110°C) with boiling points up to 220°C, and is also suitable for samples containing H2O vapor.
When used with a personal computer and the EZChrom 200 data system, the P200/P200H Micro GC allows users to:
- Analyze gas samples at their source, minimizing sample transfer complexities and delays.
- Conduct high-resolution gas analysis in mere seconds.
- Efficiently manage instrument settings, including peak identification tables, calibration tables, and integration parameters.
- Control instrument operation, upload/download experimental conditions, and monitor status.
- Catalog and retrieve chromatographic data, integrate observed peaks, and set up automated sequences.
- Perform calibration sequences and manipulate data displays using intuitive tools like zooming and scrolling.
- Generate detailed analysis reports, including area%, normalization, and external standard calculations, for robust data accountability.
- Store results in various formats for easy integration with spreadsheet applications.
Key Features and Components
Leveraging technology developed for integrated circuit manufacturing, the Micro GC's components are fabricated on silicon wafers through batch processing. This method ensures the production of repeatable, reliable, and inert components with minimal dead volume. The P200/P200H features a micromachined injection system, microbore analytical and reference columns, and a micromachined solid-state detector (SSD). This integrated design within a single GC module provides enhanced reliability and minimal band broadening, crucial for achieving high-resolution gas analysis.
