Stable HF mixtures in PPM levels
A new range of hydrogen fluoride mixtures for environmental analysis with a shelf life of six months for the environmental monitoring market have been launched into the UK market by Air Liquide
Historically it has always been difficult to obtain these mixtures because of issues over accuracy and stability In response Air Liquide began a research and development programme into the analysis and delivery of hydrogen fluoride

Created to meet the growing need in biotechnology and pharmaceutical R and D communities for individual identification of ever smaller quantities of fluid or dry samples
Some of the findings of that research were reported at Pittcon.
The result has been investment in a new centralised filling centre at Air Liquides special gas facility at Mitry-Mory complete with new analytical techniques and preparation and filling procedures.
The new product range is available in B5 and B10 cylinders (5 and 10 litres) complete with a special corrosion resistant valve fitting and so are readily transportable.
It is possible to request mixtures from the range 10 to 500ppm of hydrogen fluoride in nitrogen.
There are 18 possible mixtures available so there is a comprehensive coverage of possible requirements for users.
These products all come with a guarantee of stability for 6 months from manufacture.
David Hurren, laboratory and analysis manager UK, commented: "This new product launch shows the commitment to invest in R+D and bring forward products that are of benefit to the environmental monitoring market.
"We have ongoing developments to look to extend our range both in terms of lower levels of components such as on NOx and also to extend shelf-life such as our offer of hydrogen chloride mixtures with a three year guarantee of stability.".
