Imodeli vial incinci inokuba incinci, kodwa ulwazi lukhulu. Xa kuvela iingxaki ze-HLLC, i-vial ye-vial ihlala ijongiwe. Kodwa, ifanele ibe yeyokuqala. Xa ukhetha isampulu yasekunene vial, cinga ngezinto ezintathu: I-Septa, i-CAPS, kunye ne-vial. Eli nqaku liza kuqala ngezinto ze-vial. Iya kukwazisa ngezinto ezisetyenziswa ngokweenkcukacha. Kuya kukunceda ukhethe i-vial elungele wena.

Izazinzulu zisebenzisa izixhobo ezahlukeneyo kwi-HPPC. Zimbini eziphambili zokwenza isampulu ye-vials: iglasi kunye neplastiki.

Esona sampulu siqhelekileyo sovavanyo lwe-HPLC yi-vial yeglasi. I-vials yeglasi eqhelekileyo ifumaneka ngemibala emibini: i-amber kwaye icace. Izinto ezimbini zenza iimodeli ezimbini zesampulu. Iglasi enye eyandisiweyo ye-33 eyandisiweyo, kwaye enye ichwetheza iglasi eyandisiweyo eyi-51 eyandisiweyo. Chwetheza i-33-eyandisiweyo ye-borossilicicate ye-borosililicate glass yeyona iglasi ye-intert ifumaneka. Ilungele iilebhu zohlalutyo ukuze ifumane iziphumo ezisemgangathweni. I-Silicon Oxegen iqalise kwaye ikwanamaxabiso e-bodium kunye nesodium. Kuya kufuneka uqaphele ukuba ulwandiso lwayo lokusebenza lunokuba malunga ne-33x10 ^ (- 7) ℃. Ii-vials ziisampulu ezibonakalayo.

I-vials yesampulu ifumaneka ngemibala emibini: icacile kwaye i-brown.

I-vials ezimdaka ezenziwe ngohlobo i-33-eyandisiweyo yeglasi. Le yeyona voti isetyenzisiweyo kuvavanyo lweChromatographic. Chwetheza iglasi ye-51 eyandisiweyo i-alkaline ngaphezu kohlobo i-33-eyandisiweyo yeglasi ye-furosilicate. Iinjongo ezininzi zelebhu zinokuyisebenzisa. Ukwanda kwayo kukwanda kwe-51x 10 ^ (- 7) ℃. I-Silicon kunye neoksijini yenza ukuba iphakame, kunye ne-boron encinci ye-boron. I-vials yesampulu emdaka iquka uhlobo i-51-eyandisiweyo. Imowudi yesampulu emdaka ibhetele ekugcineni iisampulu zefonti kunendlela ebonakalayo. Kungcono ukugcina zonke iisampulu.

Ngaphandle kwezo zimbini, i-DV (DV) ikwayinto eqhelekileyo yesampulu. Ukulungiswa kweglasi engasebenziyo kufuna iinkqubo ezizodwa. Ilungele iintlobo ezahlukeneyo zesampulu. Oku kubandakanya: Iirandi zezinto eziphilayo, iisampulu zebhayoloji, iziyobisi, kunye neesampulu zokusingqongileyo, njalo njalo. Uhlalutyi bomhlaba onokuthi ubophelele kumphezulu weglasi ye-polar, iglasi yokwenza i-DeActivivation lukhetho olufanelekileyo. Abahlalutyi kufuneka babe ne-polacy eyomeleleyo. Ukuphatha i-vill yesampulu ye-vials enenqanaba lokusebenza kwenqanaba le-gesi Ungagcina i-vials eyenziweyo yomile.

Isixhobo seplastiki

Iplastiki yePolypropylene (PP) ayisebenzi. Ingasetyenziswa kwiimvavanyo apho i-vials yeglasi ayikokhetho.

Iplastiki ye-vs vs

I-vials yeplastikiIxabiso eliphantsi kwilebhu. Bayanceda ukugcina imali. Kodwa kuvavanyo olukhethekileyo, i-vials yeglasi inokumelana kuphela nokufudumeza. Ubushushu obukhulu kakhulu bunokwaphula i-vial. Inokugoba iglasi kwaye ikhuphe izinto eziyingozi. Inokwenzakalisa amava abafundi. Iya kuphendula kwakhona ngesampulu. Oku kuyakutshintsha uzinzo lwesampulu kunye nokuchaneka kohlalutyo. Ngesi sizathu, kubalulekile ukugcina isampulu yesampulu kude kubushushu obuphezulu. Ke, iibhotile ze-PP zisike ukuvezwa kwezinto eziyingozi. Banokusetyenziselwa ukuya kwi-135 ° C ngelixa betywina kakuhle ngexesha lomlilo.

Isampulu ye-GlassNgaba i-Intert kubushushu begumbi, ngelixa ezinye iisampulu zinokusabela ngeplasitics. Iglasi yimveliso ebuthathaka. Ukuba ucinga ngayo kwixesha elide, kuya kufuneka uqaphele ukuba iya kunxiba, yaphule, kwaye nokubangela ukulimala kube ngamava. Awudingi ukuba ube nexhala malunga noku nge-vials yeplastiki.

I-vils ecacileyo yesampulu ibonelela ngendlela engafihli kakuhle yokuqaphela iisampulu ezilula. Izinto ze-PP azinakufikelela ekubonakalisweni kweglasi ecacileyo.

I-vials yeglasi inezinto ezininzi zebhotile. Unokukhetha ukusuka kwiintamo zetayini, i-bayonet tops, kunye ne-crumpp tops. Kodwa, i-vials yeplastiki inee-nqual iingqungquthela ze-bayonet kunye ne-bayonet tops.

Ungaprinta amanqaku abhaliweyo kwi-vials yeglasi, eyenza kube lula ukwahlula kwaye ilawule i-vials yeglasi. Iivils zeplastiki azikwazi kuprintwa ngamanqaku abhaliweyo. Kodwa, imigca yamazika ingashicilelwa kubo. Kwaye, amanqaku abhaliweyo akasayi kutyiwa kukusetyenziswa kwexesha elide.

Ndizibuza ukuba kutheni i-vials chromatography yeGlasi ilunge ngakumbi kune-vials yeplastiki? Jonga eli nqaku lichaza:Izizathu ezi-3 eziphezulu zokuba kutheni iGlasi yeGlasi yeGeramatography ilunge ngakumbi kune-vials yeplastiki.

Okwangoku, i-vials yeglasi kukhetho lokuqala lweelebhu ezininzi zovavanyo lwe-chromatography.

Kuya kufuneka uthathele ingqalelo iimpawu zesampulu, iindleko zovavanyo, ukhetho lwakho, kunye nezixhobo zovavanyo ngelixa ukhetha i-vials. Ukuba unayo nayiphi na imibuzo malunga ne-vial yovavanyo lwakho, nceda uqhagamshelane neqela lethu lokhathalelo lwabathengi kwi-Intanethi. Bayakuvuyela ukunceda.
