Ultra high purity (UHP) is a standard that must be met in all aspects—from the gas itself to the components that handle ultra high purity gases. UHP is required for applications in industries such as semiconductor, micro-electronics, chemical and oil, as well as food and beverage processing and packaging.
Ultra high purity gas requires UHP components in the equipment that handles and processes them. These components must have an electropolished internal surface finish and be cleaned and packaged according to strict specifications. But what exactly is ultra high purity, and why is it important? Read on for details.
What Is a Ultra High Purity Gas?
Ultra high purity refers to gases with specific impurities held to levels less than 0.1 parts per million (ppm). For eUltra high purity gas refers to a state of matter with specific impurities held to levels less than 0.1 parts per million (ppm). Individual gases like oxygen, hydrogen, nitrogen, argon, and helium are considered ultra pure.
To ensure gases maintain ultra high purity, any process-handling component that comes into contact with the gas must also meet UHP standards. ChemTec’s LPH Series of flow monitors and EFV Series of excess flow valves are offered with UHP configurations to support these needs.
Industries with applications requiring Ultra High Purity standards include:
- Semiconductor manufacturing processes
- Pharma/Biopharmaceutical processes
- Food and beverage processing/packaging
- Specialty gas and chemical processes
ChemTec’s UHP-rated products can be found in custom process skids and gas delivery systems throughout these industry applications.
Semiconductor Industry
Semiconductor manufacturing devices require ultra pure gases and environments because even the smallest impurity can destroy batches of wafers during production. In the etching process, ultra high purity gases are critical to ensure the removal of any debris generated as a byproduct during fabrication.
Food & Beverage Industry
In food packaging, high purity nitrogen gas is used to preserve product quality, slow spoilage, and extend shelf life. It also cushions and protects delicate foods during handling.
Nitrogen with a concentration above 99.998% is considered a high-purity fraction and is commonly used in packaging lines where cleanliness and performance are essential.
Pharma/Biopharm
Purity is essential at every stage of pharmaceutical production. Impurities in gases—such as water vapor or foreign contaminants—can compromise outcomes or ruin the end product.
UHP gases are used both during manufacturing and packaging. A single contamination in either phase can jeopardize the entire process.
