Description

Heliox CAS NO 58933-55-4 is a specialized medical and industrial gas mixture primarily composed of helium and oxygen. This product is critical for applications requiring a low-density, high-thermal-conductivity breathing medium to reduce airway resistance and work of breathing. It is essential for the medical, diving, and aerospace industries, where precise gas mixtures are necessary for respiratory therapy, deep-sea diving operations, and leak detection. Our supply ensures consistent composition, high purity, and reliable delivery for demanding technical and therapeutic uses.

Application

• Medical Respiratory Therapy: Used in hospitals and critical care for patients with upper airway obstruction, asthma exacerbations, and chronic obstructive pulmonary disease (COPD) to improve ventilation.
• Deep-Sea Diving Gas Mixtures: Serves as a breathing gas for technical and commercial divers to prevent nitrogen narcosis and reduce breathing effort at depth.
• Leak Detection in High-Vacuum Systems: Employed as a tracer gas in the semiconductor, aerospace, and HVAC industries due to helium's small atomic size and inert properties.
• Underwater Welding and Cutting: Provides a shielding atmosphere for underwater operations where standard gases are impractical.
• Aerospace & Balloon Inflation: Used in specific applications for inflation where non-flammability and lift are required, though typically at lower oxygen concentrations.
• Research & Calibration Gas: Acts as a standard or carrier gas in analytical laboratories and for calibrating respiratory and gas analysis equipment.

Quality Control

Our Heliox mixtures are produced and analyzed under strict quality protocols to ensure precise composition, high purity, and consistency for critical applications. We provide Certificates of Analysis (COA) with each batch, detailing the exact percentages of helium and oxygen, along with verification of critical impurity levels (such as moisture, hydrocarbons, and other gases). Production adheres to relevant medical and industrial gas standards. Specifications can be customized to meet specific pharmacopeial (e.g., medical-grade) or technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store compressed gas cylinders in a well-ventilated, secure, and upright position in a cool, dry area away from direct sunlight, heat sources, and flammable materials. Keep at room temperature (15-25°C). Ensure storage area is clearly marked and complies with local regulations for compressed medical/industrial gases. Protect cylinders from physical damage and corrosion.
