The purity of gases plays a crucial role in the performance and efficiency of various applied systems. To optimize processes and applications—such as fuel gases, industrial gases, medicinal gases, and more—and reduce pollutant emissions, it is essential to analyze the purity and impurities of the gases in question.
At SIMA LABS, we are fully equipped with the necessary facilities and skilled staff for sampling and testing a wide range of gases (e.g., Biogas, CNG, PNG, gases for medical use and diving, industrial gases, and others), as per the relevant gas specifications.
Compressed Natural Gas (CNG) / Piped Natural Gas (PNG) Analysis:
We offer comprehensive analysis for gases in this category, including:
Methane, Ethane, Propane, n-Butane, n-Pentane, Iso-Butane, Iso-Pentane, Hydrocarbons (C1-C8)
Calorific Value, Methane Number, Dew Point
Impurities such as Moisture/Water Content, CO, CO2, Nitrogen, Oxygen, Oil Content, Total Reduced Sulphur (as Carbon Disulphide and Hydrogen Sulphide)

Medical oxygen is crucial for patient care in hospitals, emergency services, and home healthcare. Its purity and quality are essential for ensuring patient safety and therapeutic effectiveness. At SIMA LABS, we specialize in testing medical oxygen and gases used in medical and diving applications, adhering to ISO 8573-1 and IP-2018 standards. Our thorough testing ensures that the oxygen supplied meets the highest safety standards, free from harmful contaminants.
Why Medical Oxygen Testing Matters
The quality of medical oxygen is essential for:
Patient Safety: Contaminants in medical oxygen can pose significant risks, especially to patients with respiratory conditions.
Regulatory Compliance: Meeting industry standards and legal requirements ensures medical gas suppliers are compliant with safety norms.
Operational Integrity: High-quality medical oxygen supports the effectiveness of medical treatments and therapies.
We focus on testing three major contaminants in compressed air and gases:
Particulate Contaminants: Solid particles that may harm the gas supply.
Water: Moisture that can cause corrosion and microbial growth.
Oil: Hydrocarbon contamination that can affect medical applications.
Our testing process ensures that all medical gases, including oxygen, meet the specified purity and safety standards.
Our Testing Process
At SIMA LABS, we follow a rigorous protocol to test the purity of medical oxygen using advanced Gas Chromatographic analysis. The steps include:
Sample Collection
Medical oxygen samples are collected using sterile, contamination-free Tedlar Bags (PTFE/Polypropylene) to ensure sample integrity.
Contaminant Analysis
We perform a series of tests to measure the purity of medical oxygen, including:
Patient Safety: Contaminants in medical oxygen can pose significant risks, especially to patients with respiratory conditions.
Regulatory Compliance: Meeting industry standards and legal requirements ensures medical gas suppliers are compliant with safety norms.
Operational Integrity: High-quality medical oxygen supports the effectiveness of medical treatments and therapies.
