Facility Features, Working Principle, and Specifications:

• Features:

  • High-performance oven with fast heat-up and cool-down for shorter injection-to-injection times, ideal for high-throughput labs.

  • Twin-wall oven design with concentric air exhaust for near-ambient cooling without liquid cryogen, suitable for volatile organic compound (VOC) analysis.

  • Wide-range Flame Ionization Detector (FID) and compatibility with Mass Spectrometer (MS), Thermal Conductivity Detector (TCD), and Electron Capture Detector (ECD).

  • TurboMatrix headspace and thermal desorption systems for enhanced precision in VOC analysis.

  • TotalChrom software for data acquisition, processing, and regulatory compliance.

• Working Principle:

  • Gas chromatography separates volatile and semi-volatile compounds by vaporizing the sample and passing it through a column with a stationary phase. The Clarus 850 uses a temperature-programmable oven and various detectors to identify and quantify VOCs based on retention time and detector response.

• Body Specification:

  • Temperature range: 10°C above ambient to 450°C.

  • Oven supports 3 ramps and 4 plateaus, with run times from 0 to 999 minutes (0.1-minute increments).

  • Dual-channel configuration for simultaneous detector use.

  • Fast heat-up and cool-down rates for high throughput.

• Applications:

  • Environmental analysis (e.g., VOCs in air, water, soil).

  • Forensic and petrochemical analysis.

  • Analysis of residual solvents in pharmaceuticals.
