Bruker has announced the launch of the new G4 Icarus™ Series 2, a versatile, high-sensitivity combustion analyser for carbon and sulfur concentration measurements in inorganic samples. The G4 Icarus Series 2 extends Bruker’s line of compact, high-efficiency and low-maintenance combustion analysers by introducing novel, high-sensitivity detection technology in combination with a unique, industry-proven furnace.
The G4 Icarus Series 2 is equipped with HighSense™ LED-powered detectors based on Non-Dispersive UV (NDUV) absorption photometry for sulfur detection. In contrast to traditional IR absorption detectors, HighSense™ delivers a 10 times better signal-to-noise ratio and a linear dynamic range of five orders of magnitude with no spectral or thermal interference. Based on this novel detection technique, the G4 Icarus Series 2 outperforms conventional combustion analysers in analytical precision and accuracy, making it an excellent tool for demanding applications in academic and industrial laboratories.
The furnace zone of the G4 Icarus Series 2 is shielded by Bruker’s unique ZoneProtect™ technology, ensuring clean, efficient combustion with minimum maintenance and low cost of operation. Integrated automatic cleaning by ZoneProtect reduces cycle times to below one minute, and thereby increases sample throughput. This makes the G4 Icarus Series 2 a great choice for quality control in primary metal manufacturing, ceramics, mining and cement industries.
The elemental content of carbon and sulfur within a material has a great impact on its physical properties while the quality control of industrial processes places high demands on analytical speed, stability and uptime, ease-of-use and maintenance. Combustion analysis with the G4 ICARUS Series 2 meets and exceeds all these demanding requirements. The solid sample, placed in a ceramic crucible together with accelerator material, is heated directly using a sealed high frequency (HF) induction furnace. The molten sample is combusted in a flow of pure oxygen. The pressurised oxygen flow in combination with Bruker’s unique Zone Protect™ ensures a complete, clean combustion without undesirable side effects. Its entire flow path consists of chemically inert polymer tubing to avoid “hang-up” or “carry-over” effects and corrosion.
The ceramic crucible containing the sample and accelerator is positioned close below a gas extraction nozzle. The oxygen gas – needed for the combustion process – is supplied from the outside and flows through the annular flow gap formed between the crucible and extraction nozzle. This creates a vortex that ensures an optimal, surplus supply of oxygen to the molten sample. Liberated combustion gases and dust particles are instantly purged through the extraction nozzle, while its collar shields the quartz tube from splatters of the liquid sample. After the analysis, during the cleaning, the crucible acts as a waste bin.
