Carbon monoxide (CO) and methane (CH₄) are widely used industrial gases, but when produced and supplied in high purity and ultra high purity grades, they become true specialty gases, requiring advanced analytical control, rigorous safety measures and full traceability.
High purity carbon monoxide has long moved beyond its traditional industrial role. Today, pharmaceutical grade CO is used for medical research, reference standards, calibration gases and high value chemical synthesis, where compliance with pharmacopoeia specifications and strict certification procedures is essential. The combination of toxicity, flammability and high purity makes analytical verification a critical element of the production chain.
Methane, conversely, has become a strategic gas for the semiconductor industry when supplied at ultra high purity (UHP) levels. In applications such as chemical vapor deposition (CVD) and plasma enhanced processes, even trace level contaminants can compromise wafer yield and device performance. As semiconductor technologies continue to scale, the demand for reliable, automated and extremely sensitive gas analysis is steadily increasing.
