*   **Columns:** Dual-channel configuration with two independently controlled, user-exchangeable capillary columns. Standard columns include a non-polar (e.g., 5% phenyl polysilphenylene-siloxane) and a mid-polarity column for enhanced compound separation.

*   **Injector:** Programmable, split/splitless microfluidic injector with temperature range from ambient +5°C to 300°C.

*   **Oven Temperature Range:** Ambient +5°C to 300°C.

*   **Temperature Ramp Rate:** Programmable up to 30°C per minute.

*   **Carrier Gas:** Integrated, rechargeable helium or hydrogen carrier gas supply with advanced pressure/flow control.

**Mass Spectrometry System:**

*   **Mass Analyzer:** Linear quadrupole mass filter.

*   **Mass Range:** 45 to 500 amu (standard).

*   **Scan Rate:** Up to 10,000 amu per second.

*   **Ionization Source:** Electron Impact (EI) source with replaceable filaments.

*   **Detector:** High-energy dynode electron multiplier.

*   **Spectral Libraries:** Integrated NIST/EPA/NIH mass spectral library with search capabilities for compound identification.

**Performance & Sensitivity:**

*   **Detection Limit:** Sub-ppb to low-ppb levels for many VOCs (compound-dependent).

*   **Dynamic Range:** Greater than 10^5.

*   **Scan Modes:** Full scan and Selective Ion Monitoring (SIM) for maximum sensitivity and specificity.

*   **Vacuum System:** Maintenance-free, non-depleting ceramic high-vacuum pump.

**Software & Data System:**

*   **Control Interface:** Integrated, ruggedized touchscreen computer with intuitive graphical user interface for full instrument control, method development, and data analysis.
