Hydra II C – Solids

The Hydra IIC is a cutting-edge, fully automated analyzer designed for precise mercury measurement in solid, semi-solid, and liquid sample matrices, eliminating the need for tedious acid digestion during sample preparation. Employing the innovative technique of sample combustion (thermal decomposition), mercury concentration via gold amalgamation, and cold vapor atomic absorption detection, this state-of-the-art instrument revolutionizes mercury analysis, offering unrivaled efficiency and accuracy.


The Hydra IIC takes mercury analysis to new heights by offering direct analysis of solids, semi-solids, and liquids without the burden of sample preparation. Its ingenious operation involves a step-by-step process that ensures accurate results and eliminates the generation of hazardous waste.

Principle of Operation:

  1. Sample Preparation Made Easy: A weighed sample is placed into a sample boat and introduced into the Hydra IIC, where oxygen initiates the process.
  2. Controlled Thermal Decomposition: The decomposition furnace gradually increases the temperature to first dry the sample and then decompose it, releasing evolved gases.
  3. Mercury Concentration and Purification: Evolved gases pass through a heated catalyst, removing halogens, nitrogen oxides, and sulfur oxides, while producing free mercury. The remaining combustion products, including elemental mercury (Hg0), are swept through a drying tube and a gold amalgamation trap for concentration.
  4. Mercury Detection: After amalgamation, the trap heats up, releasing the mercury into a carrier gas, which carries it into an atomic absorption spectrometer for precise detection.

Innovative Integrated Modular Design: The Hydra IIC features a modular design that enables easy reconfiguration for different analytical techniques, ensuring adaptability to evolving laboratory requirements. This saves valuable resources, including time, money, and bench space, making it an ideal long-term investment.

Key Features:

  1. Hassle-free Maintenance: The catalyst and gold trap can be easily maintained within minutes, ensuring smooth operations and minimal downtime.
  2. Intelligent Pressure Monitoring: The system alerts users when maintenance is required, promptly addressing issues with the catalyst or sample boat injector.
  3. Impressive Usable Range: The Hydra IIC covers a wide range from 0.001 ng to 1500 ng, accommodating diverse analytical needs.
  4. Remarkably Low Detection Limit: Achieving an instrument detection limit of ≤ 0.001 ng*, the Hydra IIC delivers exceptional sensitivity without the need for sample dilution.
  5. Volatile Hydrocarbon (VHC) Mode: The instrument offers a VHC mode for specialized applications.
  6. On-the-fly Sample Programming: Effortlessly incorporate on-the-fly samples, streamlining analytical workflows.
  7. Expandable Autosampler: The 70-position autosampler can be virtually extended beyond 70 samples, enhancing throughput and flexibility.


The Hydra IIC’s exceptional capabilities make it a versatile solution for diverse applications, providing reliable results regardless of sample matrix differences. With matrix independent calibration, it offers the flexibility of using a single aqueous calibration curve or certified reference materials as standards, simplifying calibration processes.

Applications Include: Beverages, Blood, Coal, Effluent, Fertilizer, Feed, Fly Ash, Foods, Hair, Minerals, Ore, Petrochemical, Sediment, Sludge, Soil, Urine, Wastewater and Water.
