Industry Pain Points & Solutions
Oxidation, microbial contamination and inconsistent batch quality of raw materials and liquid preparations. Exposure to oxygen causes deterioration and bacterial growth in liquid medicines, active pharmaceutical ingredients, microbial strains and formulations, which may lead to full batch rejection. Conventional protection methods fail to isolate air thoroughly and cannot meet GMP sterility requirements.
Solution: High-purity nitrogen is adopted for full-process blanketing, tank protection and pipeline purging. It isolates oxygen and contaminants to maintain sterility, and ensures consistent medicinal efficacy and batch uniformity.

Substandard purity and excessive impurities of purchased gas. Pharmaceutical-grade gas demands high purity, low moisture content and freedom from microbes and particulate matter. Cylinder gas and bulk liquid gas often suffer from purity fluctuations and secondary contamination, resulting in non-compliance during random inspections.
Solution: On-site air separation units combined with downstream purification systems deliver precisely controlled gas quality, fully complying with pharmaceutical gas standards and facilitating smooth drug regulatory and GMP audits.

Insufficient oxygen supply limits capacity and yield in fermentation and cell culture.  The production of antibiotics, vaccines, probiotics and biological products relies on the aerobic metabolism of strains and cells. Traditional oxygen supply systems deliver unstable flow and inadequate dissolved oxygen, bringing extended fermentation cycles, low yield and inconsistent product performance.
Solution: Steady aeration with on-site high-purity oxygen maintains optimal dissolved oxygen levels, improving fermentation efficiency and product yield.

Raw materials are prone to moisture absorption, deterioration and caking during storage. It is difficult to stabilize temperature and humidity in raw material warehouses. API powder and Chinese medicinal materials absorb moisture and oxidize when exposed to air, shortening shelf life and increasing material losses.
Solution: Nitrogen creates an inert storage atmosphere to prevent moisture ingress, oxidation and caking, and reduce raw material rejection rate.

High fire and explosion risks from organic solvents. Flammable alcohols, ethers and esters are widely used in production, extraction and cleaning processes. Accumulation of combustible vapor in workshops, storage tanks and waste liquid areas poses severe safety hazards, especially during hot work and equipment maintenance.
Solution: Nitrogen inerting dilutes flammable gases and purges hazardous media from pipelines and equipment before maintenance, preventing fire and explosion risks from the source.
