This document is the specification sheet of Varian 450-GC CO/CO2 Analyzer, including the detection limit, configuration, operation methods and other information
The Varian 450-GC CO/CO Analyzer is designed for the accurate and reliable trace analysis of carbon monoxide, methane, and carbon dioxide in gas mixtures. It features detection limits down to low ppb levels and is available in two configurations: one optimized for hydrocarbon matrices like ethylene or propylene, and another with an enlarged sample loop for pure gases such as hydrogen, helium, and nitrogen.
The system incorporates proven hardware and column technology based on the Varian 450-GC platform. It utilizes a single channel, multi-dimensional packed column configuration with injection via gas sampling valve and detection using a methanizer and FID in series. The analyzer is fully automated for walk-away operation and includes operational procedures documented for regulatory compliance.
| Applicability | Determination of trace levels of carbon monoxide, methane and carbon dioxide in mixtures of gases. |
|---|---|
| External requirements | Sample must be gas at room temperature with a maximum pressure of 3 bar. |
| Analysis time | Approximately 15 min. |
| Minimum detectability (hydrocarbon matrices) | Better than 10 ppb. |
| Minimum detectability (pure gases) | 100 ppm. |
| Dynamic range | Between 10 ppb and 0.05% in everyday use. |
| Repeatability | Better than 1% relative standard deviation at the 50 ppm concentration level. |
| Hardware configuration | Single channel, multi-dimensional, packed column configuration based on Varian 450-GC. |
The analyzer determines trace levels of carbon monoxide, methane, and carbon dioxide in mixtures of gases.
The analysis time is approximately 15 minutes.
No, Varian was acquired by Agilent Technologies in May 2010, so the document is historical and no longer kept current.
