Kwindawo ye-chromatography, ukuchaneka kunye nokuchaneka kubalulekile ukufumana iziphumo ezinokuthenjwa. Ukhetho lwezinto eziphilayo zidlala indima ebalulekileyo ekuqinisekiseni ingqibelelo yenkqubo yohlalutyo. Iglasi kunye nee-Vials zeplastiki zizinto ezimbini eziqhelekileyo, nganye ineseti yezinto eziluncedo kunye neendlela zokuzibamba. Eli nqaku lidla ubomi bokuthelekisaIglasi ye-chromatographys vialskunye ne-vials yeplastiki, egxile kwifuthe labo ekuchanekeni kohlalutyo.

1. Ukuhambelana kwamachili

I-vials chromatographys yeglasi yenziwa ikakhulu yeglasi ye-borosilicate, impahla eyaziwayo malunga nokungavisisani kweekhemikhali. Le ndawo yenza i-vials yeglasi ilungele uluhlu olubanzi lwezicelo, zivumela abaphandi ukuba baphathe iisampulu ezahlukeneyo kunye nezinyibilikisi ngaphandle kwenkxalabo yokuphelisa izinto ezibonakalayo. Uhlobo lwe-Intert Iglasi iqinisekisa ukuba i-vial ngokwayo ayizizazi izinto zangaphandle kwisampulu, ngaloo ndlela kuphucule ukuchaneka kohlalutyo.

I-Vials yeplastiki, kwelinye icala, inokubonisa iidigri ezahlukeneyo zokuhambelana kweekhemikhali. Inkqubela phambili kwitekhnoloji yePolymer ikhokelele kuphuhliso lwezinto zeplastiki zokuchasana nokuphuculwa, kodwa abaphandi basafuna ukuvavanya ngononophelo iplastiki ethile ngesinyibilikisi kunye nesampulu abanqwenela ukuyisebenzisa. Apho kudibana nemikhalika, i-vials yeglasi kuhlala khetha ukhetho olukhethiweyo lokugcina ingqibelelo yenkqubo yohlalutyo.

I-2. Inambulelo kunye ne-adsorvo

I-intertting ye-vial yeglasi yinto ebalulekileyo ekufumaneni iziphumo ze-chromatographic ezichanekileyo. Njengoko iglasi ayisabelanga okanye ifunxa iisampulu zesampulu, uxinzelelo olulinganayo lubonisa ngokuchanekileyo ukwakhiwa kwesampulu yentsusa. Olu xinzelelo lubalulekile ekufumaneni idatha ethembekileyo kunye nokubuyiselwa kuvavanyo lokuhlaziya.

Ngokwahlukileyo, i-vials yeplastiki inokubeka umngcipheko we-adsorve, apho izinto ze-Vial zifumana iisampulu zesampulu, ezikhokelela kutshintsho kuxinzelelo kunye nokugqwetha iziphumo. Inokubakho i-adsorction ifuna ukuqondwa ngokuchanekileyo kwendlela ethile phakathi kweplastiki kunye nesampulu, ekuqwalaselweni ngononophelo lwempembelelo ezinokubakho kulungiso lohlalutyo.

I-3. Ukuqina komzimba

Ukuqina komzimba kwee-vils kubalulekile, ngakumbi kwiinkqubo ze-chromatography eziphezulu apho ii-vials ziphantsi koxinzelelo loomatshini. I-vials yeglasi yaziwa ngokuba nzima kwabo kwaye inokwenzeka ukuba iqhekeze okanye ichaphazele phantsi koxinzelelo. Oku kunyuka kuqinisekisa ukhuseleko kuzo zombini isampulu kunye nesixhobo se-chromatographic, ukunciphisa umngcipheko wexesha lokuphumla kunye nelahleko yedatha ngenxa yokuqhawula i-vial.

I-vials yeplastikiNika izibonelelo ngokwemilinganiselo yobunzima kunye nokuguquguquka, kodwa kungashenxiswa kumonakalo womzimba. Umngcipheko wokwaphuka lunokuba yinkxalabo enzulu, ngakumbi ekufumaneni iindawo zelebhu. Abaphandi kufuneka bavavanye ngononophelo iipropathi zoomatshini bee-vials zeplastiki zokuqinisekisa ukufaneleka kwabo kwiimeko ezithile zohlalutyo lweChromatographic.

I-4. I-Autosampler

I-Autosamplers zihlala zisetyenziswa kwiinkqubo ze-chromatography ze-chromatography zesampulu ezichanekileyo. Ii-vials zeglasi zihlala zihambelana ngakumbi ne-autosamplers ngenxa yemo yazo yokuzinza kunye nokuzinza. Ukufakwa kwee-vials zeglasi kwenza umsebenzi ogudileyo kunye nokuthembeka okuthembekileyo kwe-autosamplers, igalelo ekuchazeni isampulu yesampulu yokufumana isampulu kunye nohlalutyo olulandelayo.

I-vials zeplastiki iyakwazi ukwenziwa ngokungqinelana ne-autosamplers, kodwa abaphandi kufuneka baqinisekise ukuba ii-vials zeplastiki zikhetha zihlangabezane neemfuno ezithile zenkqubo yazo ezenzekelayo. Umahluko kwiipropathi ezinkulu kunye noomatshini zinokubangela iingxaki ngocwangciso oluthile lwe-autosampler kwaye zinokuchaphazela ukuchaneka kwesampula yesampuluni kwaye kungoko kuchanekile iziphumo ze-chromatographic iziphumo.

5. Imvakalelo yokukhanya

Kwimvavanyo ebandakanya iisampulu ezibuthathaka ukukhanya, ukhetho lwezixhobo ze-Vial zinokuchaphazela uzinzo lwesampulu. I-vials yeglasi yi-opaque kwaye ke ibonelela ngokhuseleko olugqwesileyo ngokuchasene nokukhanya, ukunciphisa amandla okuphendula okuphezulu okunokutshintsha ukwakhiwa kweesampulu zefonti. Oku kubaluleke kakhulu kuhlalutyo, apho ukugcina ingqibelelo yesampulu kubaluleke kakhulu.

I-Vials zeplastiki zilungele izicelo ezininzi kodwa zinokutyhilwa kukukhanya ngakumbi. Abaphandi abasebenza neesampulu ezibuthathaka ezikhanyayo kufuneka zivavanye ngolwazi ngocoselelo lwezixhobo ezikhethiweyo zeplastiki kwaye ziqwalasele amanyathelo ongezelelweyo, anjengokugcina iisampulu zeplastiki okanye ukunciphisa umngcipheko wokutshintsha kwesampulu. .

Impembelelo yokusingqongileyo

Njengoko uluntu lwesayensi luhlala lusiba nenkxalabo malunga nokuzinza, impembelelo yokusingqongileyo yezixhobo ze-visi ifumana ingqalelo eyongezelelweyo. I-vials vials ineengenelo kwiiplasitiki ezithile ngokwempembelelo yokuphinda zisebenze kunye nefuthe elisezantsi lokusingqongileyo. Iglasi inokuphinda isebenze kwakhona.Allysis kunokufuneka ukuba ithathele ingqalelo ingqalelo yohlalutyo kunye nefuthe elibanzi lwendalo lezinto ezikhethiweyo.

ISIQINISEKISO:

Ukukhetha phakathi kweglasi okanye iplastikhi yeplastikhi yeplastiki kubandakanya uvavanyo lwe-nuald zezinto ezahlukeneyo, nganye inefuthe elikhethekileyo ekuchanekeni kohlalutyo. Abaphandi kufuneka bathathele ingqalelo ukungangqinelani kwekhemikhali, ukungangqinelani, ukuqina komzimba, imvakalelo ye-autosampler, imvakalelo yokukhanya kunye nefuthe lendalo esisingqongileyo kwizinto zonke ezivaliweyo zohlalutyo.

I-vials yeglasiHlala umphezulu wokuchasana nemichiza, ukungangqinelani kunye nokuqina, kodwa inkqubela phambili kwiteknoloji ye-Vial yePlasitiki yenze i-Glass i-Glass i-vil i-vil i-vil inketho ebonakalayo, ngakumbi kwizicelo apho iMisebenzi yazo ihambelana khona iimfuno zazo zihambelana nazo iimfuno zazo. Ekugqibeleni, ukufuna ukuchaneka kohlalutyo kufuna uvavanyo lwentengiso kunye nokuqonda ngokupheleleyo indlela ezinokuthandwanga ngayo okuchaphazela ngayo ukuthembeka nokuchaneka kweziphumo.
