Has anyone ever observed signals due to phosphate additives in air compressor
oil when running 31P NMR experiments on low concentration samples? If so,
were the signals due to liquid phosphate residues coating probe surfaces or
due to vapor phase residues? In either case, how was the problem resolved?
We have a singlet at ca. -34 ppm (from H3PO4) that can be observed with or
without the sample.
Many thanks in advance. Will post summary to group.
Best regards,
Lawrence
