Ungayikhetha njani i-vials ye-HPPC

Ngovavanyo lweChromatographic, abasebenzi beLabhoratri bahlala bejamelana nengxaki yokukhetha izicelo zokukhetha amanyeneyo.Nikukhetha ukukhetha isampulu yesampulu efanelekileyo kuvavanyo kubaluleke kakhulu. Sebenzisa isampulu yesampulu engalunganga kunokubangela iziphumo ezibi zovavanyo. Inokwenzakalisa isampulu okanye i-chromatograph.

Zininzi kakhulu iitayile zeemodeli zesampulu, simele sikhethe njani? Eli nqaku liza kukubonisa indlela yokukhetha i-vials. Ukwenza njalo kuya kuphucula ukuchaneka kwakho kuvavanyo lweChromatographic.

Ukukhetha i-autosampam ye-autonampler ekunene kuyinto ebalulekileyo ekuqinisekiseni ukuchaneka kunye nokuthembeka kweziphumo zovavanyo lwakho:Amanqaku ama-5 kufuneka aqwalasele xa ekhetha i-vial ye-autosampler.

Iindidi ze-vials ze-HPPC

Sinokuhlela imizobo yesampulu ngokwesixhobo sabo, umlomo webhotile, kunye nolwakhiwo lwangaphakathi. Iindidi ezahlukeneyo zee-vial zesampulu zilungele iimvavanyo ezahlukeneyo.

Izixhobo
Phambi kokuba ukuqonde umxholo, masiqale siqonde ulwandiso lokwandiswa komgangatho. I-Coandin Ands Ands iguqukile kubude benqanaba ngalinye lobushushu. I-conder yokwandiswa esezantsi kuthetha ukuba iglasi inokumelana notshintsho lwamaqondo obushushu. Kwilizwi, yile: amandla eglasi ukuze akwazi ukumelana notshintsho lobushushu. I-USP (i-United States PharmacopeIa) iyayenza ngokwezifiso uqhelekileyo yeglasi yelebhu. Isekwe ekuchaseni amanzi.

Siyazi i-conmar ye-commar yokusebenza kweglasi. Ke, ukhetho lwezinto ezibonakalayo kwii-vic zesampulu zilula.

I-1. Uhlobo lwe-USP 1, iklasi iglasi engama-33 ye-rarosililicate yiglasi ye-hert. Isetyenziswe ngokubanzi kwiilabhoratri, ngakumbi kwi-chromatography. Iklasi iglasi iqashelwe ikakhulu i-silicon kunye neoksijini, ngexabiso le-bodium. Ine-solity esezantsi kunye nokuxhonywa komgangatho olwenziweyo onama-33.

2. Uhlobo lwe-USP 1, iklasi B 51 iglasi ye-silicon kunye neoksijini. Inexabiso elincinci le-boron, isodium, kunye neentsimbi ezininzi i-alkali kune-Glass. Ukanti, isenokufezekisa iimfuno zelebhu

I-3. Iglasi engasebenziyo okanye iglasi evaliweyo yenye yeglasi ye-borosilicicate. Senziwe i-Intert ngokuthintela umphezulu wayo nge-silanes yendalo. Kakhulu i-hydrophobic kunye ne-inert ngumphezulu weglasi. Isebenza ngempumelelo kwi-CREAMIT yesampula yexesha elide, i-PH-ejongene ne-ph-eneenkcukacha, kunye nohlalutyo lwe-trace.

I-4. Uhlobo lwe-USP kunye ne-NP Sodium-Calcium iglasi enganyangeki. Azichasanga kuneglasi ye-borossilicate.

5.I-Polypropylene yeZixhobo (PP).

Uhlobo lomlomo
I-1. I-Clamp 2. Iyolonet yomlomo 3. Umlomo womlomo

Umbala womzimba we-vials
Cacisa okanye i-amber

Ukuqwalaselwa ngokukhetha i-vials ye-HPPL

Ukuziqhelanisa
Emva kokuba uqonde umxholo we-vial ye-vial yesampulu, siza kuthetha ngokuhambelana kwayo nohlalutyo kunye nesinyibilikisi kufuneka sithathelwe ingqalelo xa ukhetha isampulu ye-vial.

1. Sebenzisa iisampulu zesampulu emdaka kwiisampulu ezibuthathaka. Iisampulu ezimdaka kwi-vials zinokufihla ngokufihlakeleyo kwaye zithintele iifoto.

I-2. Iisampulu ze-polar ezinamandla zithathwa ngokulula yiglasi, kungoko zisebenzisa imitya emiselweyo.

3. Ngombhalo ophononongwayo, sebenzisa iityhubhu zangaphakathi. Unokusebenzisa iityhubhu zangaphakathi ezingaphakathi, okanyeImodeli ephezulu yokubuyisela kwimeko yesiqhelo. Ezi zezona zisampulu ziqhelekileyo ezinevolumu encinci.

4. Kuhlalutyo lwe-IOI, sebenzisa i-vials yesampulu eyenziwe ngePolypropylene (PP), hayi i-vials yeglasi.

Khetha ngokwesampulu yesampulu

Ukufumana iisampulu ze-trace, kufuneka sisebenzise i-vials ezincinci. Benza iziphumo zovavanyo ezichanekileyo. Oku kulandelayo zii-vic ezifanelekileyo kwiisampuli zenkcazo eyahlukeneyo.

I-1. Isampulu yesampulu engaphantsi kwe-2ml
Iivileni ziza ngeendlela ezininzi.Kukho i-vials micromlemple (15μl-800μlμl) kunye nesampulu yokufumana isampulu ye-vials (i-30μl-1.5ml). Kukwakhona iityhubhu zangaphakathi (10000μl-400μl). Kukho ne-250μl i-vials ye-pialplene ye-polyproplene. Kukho neesampulu ze-vials ezixhonywe kwi-Tubs yangaphakathi yangaphakathi (250μl-300lμl).

I-2.2ml isampulu yesandla
Isampulu ye-Glass, I-polypropylene yesampulu ye-vials.

I-3. Isampulu yesampulu inkulu kune-2ml
I-4ml isampulu ye-Vials, ii-vials paishs ze-vials, iityhubhu zovavanyo, njl.

Ukuqonda iindidi ezahlukeneyo ze-vials ezisetyenziselwa i-chromatography (i-HPPC). Dive kolu vimba ukuze ufunde ngakumbi malunga nokukhetha ezona vils ezilungileyo ze-HPLC kwiimfuno zakho ezithile:I-Encyclopedia ye-vials ye-HPLC

Khetha ngokwendlela yokuvala

I-vials yomlomo edityanisiweyo zihlala zilungile kwi-LC kunye ne-LC / ye-MS. Banamathambo asezantsi kwaye baphinde basebenze. Xa kuthelekiswa ne-CRIMP cap, le ndlela yokuvala ayinabungozi kwizandla kwaye ayidingeki izixhobo ezongezelelweyo. Isikrelemnqa-kwi-Caps vial vial ifumaneka kuzo zombini ii-caps ezinesidima ezenzelwe i-autosamplers kunye ne-caps eqinileyo ezenzelwe ukugcina isampula.

I-crimp:Izixhobo ezizodwa ziyafuneka kwi-capping.Benza itywina elikhuselekileyo lamaxesha ogcino olwandisiweyo xa wambeka ekunene. I-crimp-cap yesampulu ilungele i-GC kunye ne-GC \ / IMS Izicelo. Kuba i-CRIMP ye-CRIMP ayisebenzi, ibonelela ngokhuseleko oluphezulu lokutya, ii-forensi, kunye nolunye usetyenziso apho isampulu ifunwa khona. Ukuba imiqathango eguquguqukayo iyahlalutywa, i-crimp-cap yesampulu iyacetyiswa.

I-snap ephezulu yeCAPS:Iziphumo zokutywina kwe-bayonet ayilunganga njengezinye iindlela ezimbini zokutywina. I-bayonet cap Isampuli ayinakucinezelwa, kwaye iplastiki yeplastiki ye-bayot inokugqunywe ngaphandle kwezixhobo, ezilungele kakhulu.

Sebenzisa ibhotile ye-PE ye-PE ngokutywina.Ukuxhathisa kwayo ekucoceni nasekutywineni. Kuyadideka kwaye kulula ukuyisebenzisa, kodwa ifuna ukuba iphinde iphinde iqhubeke.

Ukukhetha isiciko esifanelekileyo se-vials yakho yeChromatography kubalulekile ekuqinisekiseni ingqibelelo yesampulu kunye nokufezekisa iziphumo ezichanekileyo zohlalutyo. Nasi isikhokelo sokukunceda ukhethe i-cap cap ye-vials yakho ye-chromatography: Ungayikhetha njani i-cap ye-vials yakho ye-chromatography?
