Description

Nitrogen CAS NO 17778-88-0 is a fundamental industrial gas essential for creating inert, non-reactive environments. Its high purity and reliable supply are critical for ensuring process safety, product quality, and yield optimization across numerous high-tech industries. This product is indispensable for sectors including electronics manufacturing, pharmaceuticals, food and beverage processing, and chemical synthesis.

Application

• Inerting & Purging: Used to displace oxygen and moisture in chemical reactors, storage tanks, and pipelines to prevent oxidation, fire, and explosion hazards.
• Electronics Manufacturing: Serves as a carrier and purge gas in semiconductor fabrication, LED production, and soldering processes to protect sensitive components.
• Food & Beverage Packaging: Employed in Modified Atmosphere Packaging (MAP) to extend shelf life by displacing oxygen, preserving freshness, color, and flavor.
• Pharmaceutical Production: Provides an inert blanket during the synthesis, drying, and packaging of active pharmaceutical ingredients (APIs) to maintain stability.
• Heat Treating & Metallurgy: Used in annealing, sintering, and brazing furnaces to prevent metal oxidation and decarburization.
• Analytical Instrumentation: Functions as a carrier gas in Gas Chromatography (GC) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Oil & Gas Recovery: Injected into reservoirs for enhanced oil recovery (EOR) and for maintaining pressure in pipelines.
• Laser Cutting: Acts as an assist gas for cutting non-ferrous metals like aluminum and stainless steel.

Quality Control

Our Nitrogen is produced and tested to meet stringent industry specifications, including high-purity grades for critical applications. We ensure compliance with relevant standards such as USP-NF for pharmaceutical uses and food-grade protocols. Certificates of Analysis (COA) detailing purity, moisture, and oxygen content are provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Compressed nitrogen gas cylinders should be stored upright in a well-ventilated, cool, dry, and secure area away from heat sources and flammable materials. Liquid nitrogen must be stored in approved cryogenic containers (Dewars) to minimize evaporation and with adequate ventilation to prevent oxygen depletion. Keep container valves closed when not in use.
