Our company specializes in manufacturing accurate blends of gas mixtures. We are seeking sources of the following pure gas products…
· Isotopically characterized or purified materials, such as 13CH4, 13CD4, 14N2 (all 14N), H234S, etc.
o High purity methane with a very low 13C content.
o Higher hydrocarbons – C4s and C5s – with at least one 13C or one 12C in the molecule (location is not critical)
o Hydrocarbons where the H content is depleted in D below normal levels, e.g., C1H4, etc
· Capability of isotopic labeling or small-scale custom synthesis
o Some of our adjusting materials may have to be made “from scratch”. Can you share the names of custom manufacturers of such isotopic chemicals?
· Capability of isotope ratio mass spectrometry analysis service to accurately determine delta values for the isotopes we are interested in
o Ability to measure 34S / 32S mass ratios in gas samples is of particular interest.
Typically, gas purities of 99+% would suffice. Quantities of gases are expected to be in the 1 to 5 standard liters range each.
