what gases do we supply for absorption spectroscopy?
air products' speciality gases have been specifically designed for the analytical user and their equipment. by using the experis® gases product range, the customer can ensure accuracy of results and that their equipment performance is optimised.
bip® nitrogen
critical impurity levels of 10 ppb oxygen and 20 ppb moisture ensures equipment remains accurate for longer
bip® argon
critical impurity levels of 10 ppb oxygen and 20 ppb moisture improves equipment resolution.
synthetic air (zero air)
with low thc components, this gas is ideally suited for measuring or detecting components in very low concentrations.
acetylene
low ph₃ and h₂s specifications provide a cleaner flame with less interference, allowing for optimum analytical results.
