High-pressure, nickel-plated steel cylinder filled with a high capacity oxygen adsorbent. Low initial cost and high capacity gives months of use and reduces down time. Exceptional efficiency typically results in less than 30 ppb oxygen at the outlet.
Oxygen traps protect the liquid phase in HPLC columns from oxidation, and are particularly useful for capillary columns.
Contains 500 g of adsorbent, capable of removing over 1 L of oxygen at standard temperature and pressure.

Cu(II) complexes of N2O2 type ligands, L(1)H2 and L(2)H2 [L(1)H2 = 6,6'-(((pyridin-2-ylmethyl)azanediyl)bis(methylene))bis(2,4-di-tert-butylphenol); L(2)H2 = 2,4-di-tert-butyl-6-(((3-(tert-butyl)-2-hydroxy-5-methylbenzyl)(pyridin-2-yl-methyl)amino)methyl)phenol], have been synthesized. Addition of nitrogen dioxide (NO2) in THF solutions of the complexes resulted in the nitration at the 4-position of a coordinated equatorial
