Gas analysis devices are used to measure the composition of gases and gas mixtures. They are used in a wide variety of areas, such as gas suppliers, industry and laboratories, municipal utilities, gas plant constructors, gas transport companies and gas storage operators.
Analytical equipment for the quality control (QC) of cryogenic gases (such as liquid nitrogen, oxygen, argon, and CO2) is focused on ensuring ultra-high purity, detecting trace impurities (ppm/ppb levels), and monitoring safety. Key technologies include gas chromatography, mass spectrometry, and specific laser-based analyzers.
Applications in Cryogenic Gas QC
- Air Separation Units (ASU): Monitoring oxygen, nitrogen, and argon for contamination, typically requiring detection limits down to parts per trillion.
- Electronic/Semiconductor Gases: Utilizing Fixed Gas Purity Monitoring Systems (GPMS) to track trace oxygen and moisture in hydrogen, helium, and argon.
- Industrial/Medical Gas Quality Assurance: Utilizing Portable CQC Carts for on-site QC and certification before and after filling.
- Safety Monitoring: Utilizing Oxygen Deficiency Monitors to monitor for leaks where cryogenic liquids are vaporized.
