About www.phosphine.net
Applying a new developed gas chromatographic trace analytical technique we got
extensive knowledge concerning the existence and formation mechanisms of phosphine in the
earth’s environment. We discovered phosphine in waste gas, marsh gas, biogas,
landfill gas, wetland sediment, soil, intestinal tract of mammals, faecal sludge, animal
manure, landfill, technical metals, industrial waste, stone minerals, food and cosmic fall
down. It was also found to be a global trace component of the earth’s atmosphere. Do
not confuse phosphine (PH3) with phosgene (COCl2,
Carbonoxidechloride, Carbonyldichloride, Carbonicaciddichloride). Diphosphine (P2H4 , Diphosphane) a self igniting gas, was found in
fermentation experiments using human feacal bacteria.
(Publication:
Gassmann, G., Glindemann, D.: Phosphane in the Biosphere. Angew.Chem.Intern.Edit. 32
(1993) 761-763.). The results of this
publication, phosphine and diphosphine, was discussed in
various printed media (John
Emsley) and TV media (US discovery channel...) as
the igniter of methane gas in human flatus gas (to produce spontaneous human combustion (SHC), an appropriate
term for this would be "ignis flatus") and in marsh gas (to form swamp lights
named as Will o' the Wisp or
"ignis fatuus". A biochemical pathway of how microorganisms could produce
enzymes to reduce phosphate to phosphine is still not discovered.

Short description of the Sealing-Ring-Business of Dietmar Glindemann (efficient and economical PTFE Sealing Ring for conical glass joints)
Laboratory work with chemical glass equipment and containers often demands
hermetic and clean sealing of conical joints and stoppers. Joint grease is not solvent
resistant and not clean. The known PTFE-joint sleeves and stoppers are expensive and not
very tight. Therefore, a fine PTFE-ring seal on ground tapered glass joints has been
developed. The ring is inexpensive, gas-tight, solvent-tight, chemically inert,
temperature resistant and prevents freezing of joints. Estimated 300,000 seals have been
tested on the market in the last years.
