Nitrogen gases - Analysis of cyanogen chloride
Applications | 2011 | Agilent TechnologiesInstrumentation
This application note outlines a rapid and efficient method for detecting cyanogen chloride—a toxic gas—in ambient air. Timely identification of this compound is critical for environmental monitoring and workplace safety.
The study aimed to evaluate the performance of an Agilent micro gas chromatograph equipped with a PoraPLOT Q column for the separation and quantification of cyanogen chloride at concentrations from 1 to 20 ppm. The goal was to achieve fast analysis cycles suitable for real-world air sampling.
A micro-GC technique was employed, using an Agilent PoraPLOT Q fused silica column (0.32 mm × 10 m, df=10 μm). Helium served as the carrier gas at 200 kPa without pressure programming. The column temperature was maintained at 120 °C, and samples were injected directly (255 ms) without a heated inlet.
The method provided baseline separation of cyanogen chloride within 55 seconds. Calibration experiments demonstrated reliable detection across the 1–20 ppm range in an air matrix. Peak identification was confirmed using a composite standard and the target analyte, achieving reproducibility and low carryover.
The proposed micro-GC approach offers several advantages:
This configuration supports environmental surveillance and emergency response scenarios.
Upcoming developments may include integration with portable detectors, automated sampling interfaces, and enhanced data analytics. Expanding the method to other volatile toxicants could further bolster on-site monitoring capabilities.
The micro-GC method with a PoraPLOT Q column effectively separates and measures cyanogen chloride in air rapidly and reliably. Its simplicity and speed make it a valuable tool for environmental and industrial safety monitoring.
