Aspectus Album vel off-pulveris alba

 

Tubus spiralis conventus chromatographiae contra-currentis feliciter applicatus est in enantioseparatione dl-tryptophan utens serum albuminum bovinum sicut chiralus electrix.Melioratus biphasicus aqueus-aqueus 12.0% (w/w) polyethyleneglycol 8000-9.0% potassae dibasicae potassae phosphatae-0.1% ammoniae-78.9% adhibita est ut systema solvens pro chromatographia contra-currente, in qua Serum bovinum albumin praesertim in inferiori periodo systematis aquei utriusque temporis distributum est.Systema solvens aqueum-aqueum dedit enantioselectivity altissimas pro d- et l-tryptophan in α=2.605 cum ratione distributionis DD=1.200 et DL=0.461.Praecipuum cacumen resolutio consecuta est pro enantioseparatione 2.0mg of dl-tryptophan per tubum spiralem conventum chromatographia contra-currentem sub cella temperatura.Inventum est 0.1% ammoniae in systemate aqueo-aqueo solvendo additum valde enantioseparationes emendasse.Inusitatum apicem valde latum pro l-tryptophan in en antioseparations observatum est.Ut explicationem exponeret, missae translationis rates d- et l-enantiomers per interfaciem inter duos gradus mensurati sunt.Inventum est l-tryptophan minorem molem translationis rate quam d-tryptophan ostendit.Proponebantur ulteriores disputationes pro possibilibus causis transferendi rate differentiam inter enantiomers missam.
