1.Indlela entsha yokuphucula i-ninhydrin okanye i-1,8-diazafluoren-9-one (i-DFO)-inyangelwe iminwe efihlakeleyo yeminwe kwiphepha le-thermal iya kuchazwa.Uninzi lwemiphezulu ye-thermosensitive yephepha le-thermal iba mnyama xa iphathwa nge-DFO okanye isisombululo se-ninhydrin petroleum ether (NPB).Esi siphumo sinciphisa umahluko phakathi kweminwe ephuhlisiweyo kunye nemvelaphi.Indlela entsha echazwe inciphisa le nkunkuma emnyama ngaphandle kokususa umaleko we-thermosensitive kunye neenxalenye zeminwe ephuhlisiwe, njengoko kwenzeka ngokuhlamba i-acetone.Ngendlela entsha, iminwe ephuhlisiwe ibonakala kwimigca ebukhali kunye nokuchasana okuphezulu.Uvavanyo olubanzi lwenziwa, olukhokelela kwisisombululo esilungisiweyo sokusebenza, esihlawulisa iphepha ngobuncinci beekhemikhali, zingabizi, kwaye zenza ukuba ubuninzi bamaphepha baphathwe ngexesha elifutshane.Isisombululo esisebenzayo siqulethe izinto ezithengiswayo, ezingaguqukiyo, i-nitrogenous organic compounds kwaye zingasetyenziswa njengokusetyenziswa kwesisombululo se-NPB ngokudipha.
I-2.Eli phepha lichaza isifundo sokuphendula phakathi kwe-1, i-8-diazafluoren-9-enye (i-DFO) kunye ne-amino acid L-alanine kwi-methyl alcohol.Inzala ethile yahlawulwa kwindima enokwenzeka yesinyibilikisi ebonakala ngathi isabelana ne-DFO ukwenza i-hemiketal eluhlobo olusebenzayo.Indlela yokusabela enokwenzeka iyacetywa ngokusekelwe kwidatha yangoku eqokelelweyo.Iziphakathi zokusabela kunye neemveliso zachongwa ngeendlela ezahlukeneyo ze-spectroscopic ezibandakanya i-mass spectrometry (MS), i-nuclear magnetic resonance (NMR) spectroscopy, kunye ne-X-ray crystallography.
