Designed primarily for use as a carrier gas in gas chromatography (GC), the Trace 250 precision hydrogen generator is also suitable for detectors that require a hydrogen-on-demand solution for fuel gases such as FID and FPD. One generator can power multiple GC instruments. This generator provides a safe, reliable and convenient solution for users using hydrogen as a GC carrier gas. It produces the highest purity Hydrogen from the Precision Series by using a proton exchange membrane to produce hydrogen gas from deionized water. Pressure swing adsorption and molecular sieve technology are also used to reduce moisture content to trace levels. The Precision Hydrogen Trace Generators are also suitable for providing collision gas for ICP-MS. Characteristics:. Suitable as a flame and carrier gas at trace detection limits. 99.99999%* purity. Internal leak detection with automatic shut-off function. Proven PEM technology for safe and reliable hydrogen production. Regenerative PSA dryers for maximum purity. Automatic charging pump as standard. Maintenance is limited to replacing the deionizer cartridge. Compact, space-saving module design. Generates hydrogen on demand, minimal storage of hydrogen in the system. Combination of multiple units possible for higher flow requirements. GC oven hydrogen leak detector available as an optional extra. Precision air compressor (110V model). The Precision Air Compressor is specifically designed and engineered to provide a dedicated, fully integrated source of compressed air for Precision Nitrogen and Precision Zero Air Gas Generators. Housed in the same compact, stackable format as the generators, the Precision Air Compressor Module can be added to any Precision stack – typically as a base unit – to create a complete, self-contained GC gas solution, even in the absence of home supply. Through a unique duplex compressor mounting system, the Precision Air Compressor also benefits from low noise and vibration, making it relatively quiet when operating within a typical laboratory. Characteristics:. Compressed air supply for Precision nitrogen and zero air generators. One unit can power both the Precision Nitrogen and Zero Air Generators in one stack. Duplex compressor mounting system to dampen noise and vibration. Service & repair status display. Precision zero air 1.5 gas generator. The Precision Zero Air Generators are specifically designed to provide clean, dry, hydrocarbon-free air as a flame supporting gas for GC at standard and trace detection limits. As with all Precision Series generators, Zero Air benefits from a compact and modular, stackable design that minimizes the overall space required for GC gas supply and provides flexibility to add or remove modules as laboratory needs change over time. Characteristics:. Integrates seamlessly with other Precision units. Hydrocarbon content (as methane) < 0.05 ppm for leading purity in the market. Minimal lifetime maintenance requirements, no expensive spare parts for catalyst chambers. Avoiding the risk of contaminants entering the system when changing empty cylinders. No risk of running out of gas in the middle of the analysis. Compatible with the Precision air compressor. Status indication via lighting characteristics (amber warm-up, green ready) Labprocure is responsible for this device.
