Key Components:

1. PKD Detector Assembly: The core component. This is a cryogenically cooled (likely liquid nitrogen, LN2) mercury cadmium telluride (MCT) detector optimized for specific infrared wavelengths. PKDs generally offer higher sensitivity and lower noise compared to older pyroelectric detectors like the SSL71, which is critical for trace analysis.
2. Dewar Flask: A vacuum-insulated flask for holding liquid nitrogen to cool the detector.
3. Mounting Hardware & Cables: Necessary brackets, connectors, and wiring harnesses to properly install the new detector into the existing instrument (likely a gas chromatograph or spectrophotometer from Thermo, such as models in the Trace GC or ISQ series).
4. Software/Firmware Updates: Installation media or instructions for updating the instrument’s control software to recognize and properly operate the new PKD detector.
5. Documentation: Installation manuals, calibration procedures, and safety datasheets.

Purpose of the Upgrade:

• Improved Sensitivity (Trace Analysis): The primary reason for this upgrade. The PKD detector is far more sensitive than the SSL71, enabling the reliable detection and quantification of Selenium (Se) and likely other compounds at very low concentrations (parts-per-billion or lower).
• Enhanced Performance: Lower noise, better signal-to-noise ratio, and improved stability for demanding applications.
• Modernization: Upgrades older instrument configurations to newer detector technology, extending the useful life and capabilities of the existing system.

Typical Application:

This upgrade kit was commonly used in systems like the Thermo Trace GC with an SCD (Sulfur Chemiluminescence Detector) or other elemental-specific detectors. The upgrade to a PKD would be for applications requiring ultra-trace detection of selenium-containing compounds, such as:

• Environmental analysis (water, soil)
• Petroleum and fuel analysis
• Pharmaceutical and chemical industry
