Kwihlabathi lohlalutyo lwekhemikhali kunye novavanyo lwelabhoratri, ukuchaneka kubalulekile. Nokuba wenza ichromatography okanye olunye uhlalutyo, umgangatho wesixhobo sakho ukuchaphazela ngokuthe ngqo ukuthembeka kweziphumo zakho. Elinye icandelo elibalulekileyo elihlala lingahoywa yisampulu yelophu ngaphakathiI-agilent autosampler injectors. Le nxalenye encinci kodwa ebalulekileyo iqinisekisa ukuba iisampulu zifakwe ngokuchanekileyo kwinkqubo, echaphazela ukusebenza ngokubanzi kunye nokusebenza kakuhle kohlalutyo.
Kodwa yintoni kanye eyenza isampulu yesampulu elungileyo, kwaye kutheni izinto zayo zibaluleke kangaka? Kweli nqaku, siza kuphonononga indima yeesampulu zesampulu, izixhobo ezisetyenzisiweyo, kunye nendlela yokukhetha ezona ndlela zilungileyo zokuseta elabhoratri yakho.
Yintoni iSampuli yeLoop kwaye kutheni ibalulekile?
Isampuli yesampulu yinto encinci, i-tubular component ngaphakathi kwe-autosampler injector system ephethe umthamo ochanekileyo wesampuli ngaphambi kokuba ifakwe kwi-chromatograph okanye ezinye izixhobo zokuhlalutya. Injongo yalo kukuqinisekisa ukuba isampuli esitofiweyo ngumthamo ochanekileyo, ochaphazela ngokuthe ngqo ukuchaneka kunye nokuveliswa kweziphumo zovavanyo.
Imiqulu yesampulu engachanekanga ingakhokelela kwidatha egwenxa, ekhokelela kwiimpazamo ezinokuthi zibekho kuhlalutyo kwaye ekugqibeleni zichaphazele uphando okanye iziphumo zemveliso. Ngoko ke, ukuqinisekisa umgangatho kunye nokuchaneka kwesampulu yesampulu kubalulekile ekufumaneni iziphumo ezithembekileyo kwiinkqubo zokuhlalutya.
Umba wezinto: Intsimbi engatyiwayo vs. PEEK
Izinto ezisetyenziselwa ukwakhiwa kwesampulu yesampulu zinokuchaphazela kakhulu ukusebenza kwayo kunye nokuphila ixesha elide. Izinto ezimbini eziqhelekileyo ezisetyenziselwa ukwenza iilophu zesampulu zeziyenziwe ngentsimbi eshayinayokwayeI-PEEK (I-Polyetheretherketone). Makhe siphonononge ukuba ezi mathiriyeli zahluka njani kwaye kutheni nganye ingalungela iimfuno ezahlukeneyo zelabhoratri.
Iisampulu zesampulu yentsimbi engatyiwayo
Intsimbi engenastainless ibiyinto yokuya kwisampulu yesampulu yelophu iminyaka emininzi. Eyaziwayo ngokuhlala kwayo, ukuxhathisa ukubola, kunye nokukwazi ukumelana noxinzelelo oluphezulu, insimbi engenasici inika umsebenzi obalaseleyo kwiindawo ezininzi zebhubhoratri. Isakhiwo sayo esiqinileyo siqinisekisa ukuba isampuli yesampulu igcina imilo yayo kunye nokunyaniseka, ukunciphisa umngcipheko wokuvuza kunye nokulahleka kwesampuli ngexesha lokutofa.
Ukongeza, insimbi engenasici iyamelana noluhlu olubanzi lweekhemikhali, iyenza ilungele ukusetyenziswa kwizicelo ezahlukeneyo apho uzinzo lweekhemikhali lubalulekile. Nangona kunjalo, iilophu zentsimbi engenakutyiwa zisenokungalungeli iisampulu ezinovakalelo kakhulu okanye iimeko ezifuna amanqanaba asezantsi kakhulu okungcoliseka, njengoko imathiriyeli ngamanye amaxesha inokunika umkhondo wesinyithi kwisampulu.
I-PEEK iSampule yeLoops
I-PEEK yipolymer esebenza kakhulu eyaziwa ngokuba yi-inertness yayo yeekhemikhali, amandla omatshini, kunye nokuchasana nokushisa okuphezulu. Iisampulu zesampulu zelophu ezenziwe kwiPEEK ziluncedo ngakumbi kwizicelo ezinovakalelo apho ungcoliseko oluvela kwisinyithi okanye ezinye izinto ziyinkxalabo. Iimpawu ze-PEEK ezingasebenziyo ziqinisekisa ukuba ayisebenzi kunye nesampuli, iyenza ibe yinto efanelekileyo yokuphatha izinto eziguquguqukayo okanye ezisebenzayo.
Enye inzuzo ye-PEEK kukuguquguquka kwayo kunye nobunzima obulula xa kuthelekiswa nensimbi engenasici, enokwenza kube lula ukuphatha ngexesha lofakelo okanye ukutshintshwa. Nangona kunjalo, i-PEEK ayinakumelana noxinzelelo oluphezulu kunye nensimbi engenasici, ngoko ke ukusetyenziswa kwayo ngokuqhelekileyo kunconywa kwiinkqubo zoxinzelelo oluphantsi.
Ungayikhetha njani iSampuli eLungileyo kwiSicelo sakho
Ukukhetha isampulu yesampulu elungileyo kuxhomekeke kwizinto ezininzi, kuquka ubume besampulu, uhlobo lohlalutyo, kunye nokusingqongileyo okusebenzayo. Nazi ezinye izinto ekufuneka uziqwalasele xa ukhetha imathiriyeli yesampulu yesampulu yakho:
1. Uhlobo lweSampuli: Ukuba usebenza ngeesampulu ezinovakalelo okanye eziguquguqukayo, isampulu yesampulu yePEEK inokuba lolona khetho lungcono ngenxa yobume bayo bokungasebenzi. Nangona kunjalo, kwizicelo ezinamandla ngakumbi okanye kwimizi-mveliso, insimbi engenasici inokuba lolona khetho luhlala ixesha elide.
2. Ukuhambelana kweMichiza: Zombini izixhobo zinika ukuchasana okuhle kwiikhemikhali, kodwa kwiimeko ezigqithisileyo zeekhemikhali, insimbi engenasici inokugqwesa iPEEK. Ngalo lonke ixesha qinisekisa ukuba izinto ozikhethayo ziyahambelana nezinyibilikisi kunye nee-reagents ezisetyenziswa kuhlalutyo lwakho.
3. Iimeko zoxinzelelo: Ukuba inkqubo yakho isebenza kuxinzelelo oluphezulu, insimbi engenasici inokuba lolona khetho lungcono njengoko inokumelana nale meko ngaphandle kokuthomalalisa ingqibelelo yayo.
4. Ukuqina: Insimbi engenasici yinto ehlala ixesha elide, ngakumbi kwiinkqubo ezifuna ukusetyenziswa rhoqo. I-PEEK, ngelixa iqinile, ayinakuhlala ixesha elide phantsi kokusetyenziswa kakhulu okanye iimeko ezinzima.
5. Ubungakanani kunye nokuguquguquka: Ukuba ukuguquguquka kunye nokulula ukufakela kubalulekile, iilophu zesampulu zePEEK zibonelela ngenketho elula kwaye eguquguqukayo. Ngakolunye uhlangothi, insimbi engenasici, inika ukuqina, okunokuthi ngamanye amaxesha kuthembeke ngakumbi kwiinkqubo ezithile.
Ukuqukumbela
Iisampulu zesampulu ziyinxalenye encinci kodwa ebaluleke kakhulu kwi-Agilent autosampler injectors, kwaye ukukhetha izinto ezifanelekileyo kwilophu yakho kubalulekile ekuqinisekiseni ukuchaneka, ukusebenza kakuhle, kunye nokuphila ixesha elide kwiinkqubo zakho zohlalutyo. Nokuba ukhetha insimbi engenasici okanye i-PEEK, ukuqonda izibonelelo zesixhobo ngasinye kuya kukunceda wenze isigqibo esinolwazi malunga neemfuno zakho zelabhoratri.
Ngokutyala imali kwisampulu yesampulu ekumgangatho ophezulu kunye nokugcina izixhobo zakho rhoqo, unokuphucula ukuchaneka kohlalutyo lwakho kwaye ufezekise iziphumo ezithembekileyo ngalo lonke ixesha. Ukuba ukulungele ukuphonononga iisampulu zesampulu ephezulu kwilabhoratri yakho,Chromasirinikeza uluhlu lweenketho zokusebenza eziphezulu ukuhlangabezana neemfuno zakho.
