Packaging

All gas volumes are quoted at Standard Temperature and Pressure (STP) and not at Normal Temperature and Pressure (NTP). One STP Liter is 7.7% more gas than one NTP Liter.
Standard products are packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180 valve. Nominal gas pressures at 21ºC are 850 psig for 25 L and 1570 psig for 45 L. Care must be taken when extracting this product from the cylinder.
This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.

Recommended products

Stainless steel control valves Z146951, Z187224 or either of stainless steel regulators Z148504 and Z148512 is recommended.

A general method to analyze the structure of a supramolecular complex of amyloid fibrils at amino acid residue resolution has been developed. This method combines the NMR-detected hydrogen/deuterium (H/D) exchange technique to detect hydrogen-bonded amide groups and the ability of

Electrospray ionization (ESI) mass spectrometry (MS) is a powerful analytical tool for elucidating structural details of proteins in solution especially when coupled with amide hydrogen/deuterium (H/D) exchange analysis.

Probing the conformational changes of amyloid beta (Aβ) peptide aggregation is challenging owing to the vast heterogeneity of the resulting soluble aggregates. To investigate the formation of these aggregates in solution, we designed an MS-based biophysical approach and applied it
