The 1 L quantity option is packaged in a 450 mL carbon steel lecture bottle with a brass CGA 110/180 valve. Nominal gas pressure at 21ºC is 20 psig for 1 L. This pressure is slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder. 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.

Opis ogólny
Oxygen-18O2 is a naturally occurring stable isotope of oxygen. Natural abundance of 18O2 containing at least 99 atom % O-18.
Zastosowanie
18O2 isotopic labelling was employed, in conjunction with time-of-flight secondary ion mass spectrometry, to characterize and elucidate the parts of the degradation mechanisms induced by molecular oxygen. Using 18O2 as a label, it is possible to study collagen degradation with this non-reutilized label and so avoid the large errors that are introduced by the recycling of other labels.
Oxygen-18O2 can be used to study the kinetic and functional analyses in photosynthesis research. It is used to estimate the role of oxygen in the vitamin-K dependent carboxylation reaction. Also used to measure the amount of oxygen produced by the etching a quartz tube with SF6 plasma.

Monitoring isotopic compositions of gaseous products (e.g., H2, O2, and CO2) by time-resolved isotope-ratio membrane-inlet mass spectrometry (TR-IR-MIMS) is widely used for kinetic and functional analyses in photosynthesis research. In particular, in combination with isotopic labeling, TR-MIMS became an essential
