Domestic Ion Chromatography madaidaiciyaBayani:

An auna nau'ikan ion a cikin mafita shine babban abu na gargajiya na binciken sinadarai. Ana samun wasu hanyoyin nazari masu sauri da hankali na anion, kamar sha atomatik, ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙaranc Wadannan hanyoyin suna da tsawon lokaci, suna buƙatar nau'ikan sinadarai da yawa, ƙananan ƙwarewa da tsangwama. Chromatography na ion yana da fa'idodi na sauri, m, zaɓi mai kyau, da kuma auna abubuwa da yawa a lokaci guda, da yawa daga cikinsu sune ions da ke da wuya a yanzu a auna su ta wasu hanyoyi, musamman anions. Binciken ion chromatography na anions sabon ci gaba ne a cikin binciken sinadarai. Idan high mita inductive coupled plasma fitar da spectrum-mass spectrum (ICP-MS) ne a halin yanzu a lokaci guda da sauri, m da kuma daidai bincike hanyar auna multi-abubuwa, to, a lokaci guda da sauri, m da kuma daidai bincike hanyar auna da yawa anions lokacin da * ion chromatography.

Abubuwa:
1. Sauri da sauki
A zamanin zamani, lokacin da ake bukata don kammala aikin bincike yana da mahimmanci. A kan 7 al'ada anions (F)^-、 Cl^-、 Br^-、 NO₂^-、 NO₃^-、 SO₄^2-、 PO₄^3-da shida na yau da kullun cation (Li 、 Na 、 NH4 、 K 、 Mg² 、 Ca² Matsakaicin lokacin bincike ya kasance ƙasa da 10min. rabuwa na yau da kullun anions da aka ambata bakwai zui muhimmanci tare da inganci da sauri rabuwa ginshike dauki kawai 3min.
Sauƙin amfani yana daya daga cikin alamun ci gaban IC na zamani. Wasu matsalolin da masu amfani ke jin matsala an magance su mafi kyau. Misali NaOH shine mai shawarar da aka ba da shawarar don nazarin anions a cikin IC mai hana sinadarai, saboda samfurin halayen hana shi shine ruwa mai ƙarancin wutar lantarki. Amma CO a cikin iska lokacin da aka tsara da kuma amfani₂Koyaushe yana narkewa a cikin mafita na NaOH kuma yana samar da CO₃^2-, sa tushen line yawo, wani lokacin kuma bayyana ghost peaks. Yanayin samar da launi na kan layi bisa ka'idar electrolysis yana guje wa tuntuɓar launi da iska, kawai amfani da linzamin kwamfuta a tashar aiki don samun daidai matakin da ake buƙata na launin KOH mara gurɓataccen launi. Har ila yau, kamar electrochemical membrane inhibitor, babu buƙatar sake dubawa, za a iya ci gaba da aiki.

2. High hankali
Yankin matattarar nazarin ion chromatography shine μg / L-mg / L. Kai tsaye samfurin 50μl, da detection iyaka ga yau da kullun anions kasa da 10μg / L. High tsabtace ruwa da ake amfani da wutar lantarki, nukiliya wutar lantarki da kuma semiconductor masana'antu, ganowa iyaka har zuwa 10 ta hanyar kara yawan samfurin da kuma amfani da kananan rami ginshike (2mm diamita) ko online taro^-12g / L ko ƙasa. Ingantaccen ƙwarewar ganowa sau da yawa yana da alaƙa da ingantaccen zaɓi kamar haɗuwa da IC tare da inductive-coupled plasma-mass spectrum (ICP-MS): iyakokin ganowa don arsenic, gubar, tin, mercury, chromium, titanium, phosphorus, sulfur, vanadium, da nickel suna 20, 0.2, 2, 7, 20, 1, 400, 7000, 110, da 30pg, bi da bi. IO don anion₃^-, BrO₃^-， Cl^-， ClO^₃-, Br^-kuma I^-Gano iyaka ne: 25ng iodine, 0.8ng bromine da 36ng chlorine bi da bi.
Idan aka kwatanta da hanyar ICP-MS, amsa da aka samo bayan ginshiƙi hanya ce mai ƙarancin farashi da sauƙi don haɓaka ƙwarewar ganowa.

3. Good Zaɓi
Binciken hanyar IC na zaɓi na inorganic da organic anionics ana samun shi ne ta hanyar zaɓar tsarin rabuwa da ganowa mai dacewa. Idan aka kwatanta da HPLC, mafi girman tasirin zaɓi na gyare-gyare a IC.

Lokacin da ake amfani da na'urorin ganowa na lantarki, fasahar hana yana da mahimmanci saboda zai iya zama antiionic (misali na NaCl) na ion da ake auna a matsayin tushen tsangwama.^-Lokacin da Na Domin anti-ion, auna NH₄NO₃tsakiyar NH₄ Lokacin da NO₃^-a matsayin anti-ion) a cikin halayen hana zai zama daban-daban tare da H ko OH^-Musayar, shiga cikin sharar ruwa. Yin amfani da masu gano halaye masu narkewa don inganta zaɓi na wasu nazarin samfuran rikitarwa kamar Cl^-Babu sha UV,
Kuma ba₃^-kuma NO^₂-Tare da karfi UV sha, zaɓi tare da UV-gani detector iya gano high Cl da sauƙi^-NO daga₂^-kuma NO₃^-. Ci gaban hanyoyin da aka samo bayan ginshiƙi ya haɓaka zaɓin ganowa na ƙarfe ions, polyvalent anions da sulfates da sauransu. Saboda zaɓin IC, buƙatun samfurin kafin sarrafawa suna da sauƙi, kuma yawanci kawai ana rarraba su da tacewa.

4. Za a iya bincika daban-daban ion mahada lokaci guda
Idan aka kwatanta da hanyar photometry, hanyar sha atomatik, babban amfanin IC shine gano abubuwa da yawa a cikin samfurin lokaci guda. Za a iya samun cikakken bayani game da yin, cation da kuma samfurin samfurin a cikin ɗan gajeren lokaci. Amma wannan ikon ganowa lokaci guda ya iyakance ta hanyar babban bambancin matattarar tsakanin abubuwa daban-daban a cikin samfurin. Misali, yana da wuya a gano babban matattarar da ƙananan matattarar abubuwa a cikin samfurin ruwan sharar gida a lokaci guda, binciken irin wannan samfurin sau da yawa ana amfani da saitunan ƙwarewa daban-daban ko matakan rarrabuwa daban-daban don samun samfurin sau biyu ko fiye.

5. Good kwanciyar hankali na raba ginshike, high karfin
kwanciyar hankali na raba ginshiki ya dogara da nau'in ginshikin cikawa. Ba kamar silicone cikawa da aka yi amfani da shi a HPLC, styrene / polyethylene benzene polymer a IC ne mai amfani da shi sosai. Babban kwanciyar hankali na pH na wannan resin yana ba da damar yin wanki tare da acid mai ƙarfi ko alkali mai ƙarfi, wanda ke da amfani don fadada kewayon aikace-aikace. Sabon nau'in resin mai haɗin kai yana da kwanciyar hankali a cikin mai narkewa. Saboda haka za a iya wanke ginshiƙi tare da mai narkewa don cire gurɓataccen abu. Babban kwanciyar hankali na pH da daidaitaccen mai narkewa na kwayoyin halitta, da kuma babban ƙarfin ginshiƙi, yana sauƙaƙe tsarin sarrafawa kafin samfurin. narkewa, dilution, da tacewa ne manyan abubuwa a cikin samfurin a IC kafin sarrafawa.
