1. Isilinganiso se-Photometric: Ungakhetha ubude begagasi bokuhlola bephoyinti elilodwa kanye nendlela yokuhlola oyidingayo phakathi kwebanga elingu-320-1100nm ukuze unqume ukumunca noma ukudluliswa kwesampula.Ungakwazi futhi ukufunda ngokuqondile ukugxila kwesampula ngokufaka i-concentration evamile noma isici sokuhlushwa.
2. Isilinganiso sobuningi: Linganisa isisombululo sesampula sokugxila okungaziwa ngokusebenzisa ijika lezinto ezaziwayo zepharamitha noma umise ngokuzenzakalelayo ijika lesixazululo elijwayelekile;nge-oda lokuqala, i-oda lokuqala lokuwela u-zero, i-second-order, ne-third-order curve fitting, nokulungiswa kwe-wavelength eyodwa, ukulungiswa kwe-isoabsorption okuphindwe kabili kwe-Wavelength, indlela enamaphuzu amathathu ozikhethela yona;ijika elijwayelekile lingagcinwa futhi likhunjulwe;
3. Isilinganiso sekhwalithi: Setha ububanzi be-wavelength nesikhawu sokuskena, bese ukala ukumunca, ukudluliswa, ukuboniswa namandla amasampuli aqinile noma awuketshezi ngezikhathi ezithile.Ingakwazi futhi ukusondeza, ukushelela, isihlungi, ukubona, ukulondoloza, ukuphrinta, njll. kwe-spectrum elinganisiwe;
4. Ukulinganisa isikhathi: Ukulinganisa isikhathi kubizwa nangokuthi ukulinganisa kwe-kinetic.Isampula iskenwa ngezikhawu zebanga lesikhathi lokumunca noma ukudluliswa ngokuya ngephoyinti elimisiwe lobude beza.Ukumunca kungaguqulelwa ekubenilwa kwesilinganiso sokugxilisa ingqondo noma ukusabela ngokufaka isici sokuhlushwa.
Ukubalwa kwesilinganiso sokusabela kwe-enzyme kinetic.Izindlela ezahlukahlukene zokucubungula imephu njengokukala, ukushelela, ukuhlunga, ukutholwa kokuphakama kanye nesigodi, nokuphuma kuyatholakala ngokukhetha kwakho;
5. Isilinganiso se-wavelength eningi: Ungasetha amaphoyinti angama-wavelength angama-30 ukukala ukumunca noma ukudluliswa kwesixazululo sesampula.
6. Imisebenzi yokusiza: isikhathi sokuqongelela sokukhanyisa isibani se-tungsten, isibani se-deuterium, isibani se-tungsten esizimele sivaliwe futhi sivuliwe, i-UV kanye nokukhanya okubonakalayo okushintshwayo kokukhetha iphuzu le-wavelength, ukukhethwa kolimi lokusebenza (isiShayina, isiNgisi), ukulinganiswa kwe-wavelength okuzenzakalelayo.
