An difríocht idir uigí níolón agus PP: Go ginearálta, déantar uigí níolón a fhí ar dtús agus ansin daite, agus mar sin beidh dath an snáth tar éis a ghearradh ag casadh bán mar gheall ar ruaimniú míchothrom, agus an uigí PP daite ar dtús agus ansin fite, mar sin ní bheidh sé. Tá feiniméan ann go bhfuil an snáth bán; i gcodarsnacht leis sin, tá an uigí níolón lonracha agus níos boige ná an uigí PP; is féidir é a idirdhealú freisin trí imoibriú ceimiceach dócháin; go ginearálta tá praghas an uigí níolón níos airde ná praghas an uigí PP.
