Uhlobo lwe-Vial luchaphazela njani uhlalutyo lweengcongolo zezinto eziphilayo

Xa ihlalutya amabala e-orlat organisayo Uqwalaselo lomgaqo we-vial lunempembelelo ebonakalayo ekusebenzeni kwemali yokuqokelelwa kwesampulu, ingqibelelo yohlalutyo, kunye nokuchaneka kweziphumo zokuhlaziya. Eli nqaku lichaza indlela iintlobo ezahlukeneyo zokugqiba ezinokuthi zichaphazele ngayo uhlalutshelo lwe-VOC kwaye igxininise ingqalelo ebalulekileyo kubaphandi kunye neengcali ze-lab.

Ukuqonda iintlobo ezahlukeneyo zeCAPS ye-vial

Uhlobo lwentamo ye-vil ibhekisa kwiyilo kunye nobungakanani bokuvulwa okuphezulu kwe-vial. Ukuqwalaselwa okuqhelekileyo zezi zilandelayo:

I-screw-ephezulu ye-vials: i-vials enentanye yetrinta kunye ne-screw-cap ephezulu yokuvalwa okukhuselekileyo. Zithandwa kakhulu ukuba zisebenzise kwaye zomelele, ekubaluleke kakhulu ukugcina ingqibelelo yesampulu.

I-crimp-ephezulu ye-vials: Ezi vils zinentamo egudileyo kwaye zifuna isixhobo sokukhusela ukukhusela i-cap yentsimbi kwirabha okanye i-silicone septum. Olu luyilo lubonelela ngetywina elihle ukuthintela ukuphulukana kweVOC kwaye kufanelekile kwiisampulu eziguqukayo.

I-vials ephezulu ye-Snap: Ezi vils zine-cap-ephezulu ye-snap-ephezulu yokufikelela ngokukhawuleza, kodwa ungatywina kunye ne-screw-top-ephezulu ye-vials. Oku kuqhelekileyo kusetyenziswa iisampulu ezingalunganga.

Impembelelo yesampula ye-BOTTLE yohlalutyo lweVOC

Ukukhetha uhlobo lwentamo ye-Vial kuchaphazela iinkalo ezininzi zohlalutyo lweVOC.

1. Ixabiso lesampulu kunye nokuzinza

Enye yezona zinto zixhalabisayo xa zihlalutya i-VOCS kukugcina ingqibelelo yazo kwiSampu kunye nenkqubo yohlalutyo. Uhlobo lwentamo ye-Vial lidlala indima ebalulekileyo ekuthinteleni ukuphuma.

I-vials edityanisiweyo: Uyilo olunentambo lubonelela ngetywina eliqinileyo, ukunciphisa umngcipheko we-VOC ukuvuza ngexesha lokugcina kunye nohlalutyo. Oku kubaluleke kakhulu kwiisampuli ezinokuthathela ingqalelo ukuvezwa kwe-themosfic.

I-crimpp vials: I-crmimd itywina libonelela ngetywina lomoya, ukunciphisa amandla elahleko yeVOC ngokuvela. Oku kubalulekile xa ujongene neendawo ezixineneyo kakhulu ezibaleka ngokulula kwimozulu.

I-SNAP COCS vials:I-Snap CAPSzilungele, kodwa azitywili kunye ne-screw okanye i-crimps caps kwaye zisiba mbi ngakumbi, ezinokubangela ukulahleka kohlalutyi.

I-2. Ukuphelisa ukhathalelo lwesampula

Uyilo lwentamo ye-vil likwachaphazela ukukhululeka kwesampulu kunye nohlalutyo.

I-Vials edityanisiweyo: Ezi vils kulula ukuzisebenzisa kwaye zinokuvulwa ngokukhawuleza kwaye zivaliwe ngaphandle kwezixhobo ezizodwa. Oku kuba lula ukusebenzisa lula i-gooclow kwilabhoratri exakekileyo.

I-crimpp ephezulu ye-vials: crimps vils pials itywina kodwa kodwa ifuna izixhobo ezongeziweyo (isixhobo se-CruimP) esiya kutywina kwaye sivuleke, esinokuthi sinciphise ixesha lokwenza isampula.

I-Snap ephezulu ye-vials: Uyilo olulula luvumela ukufikelela kwesampulu ekhawulezileyo, kodwa oku lula lula kuya kuba ngumlinganiso kwimicimbi enokubakho ngengqibelelo yesampulu.

I-3. I-Autosampler

Iilebhu ezininzi zisebenzisa i-autosamplers ukuba ikhuphe iisampulu kwiinkqubo zabo ze-GC. Uhlobo lomphezulu we-Vial lubalulekile ukuze kulungiswe ezi zixhobo zilandelayo:

I-vials edityanisiweyo: Uninzi lwee-autosample zenzelwe ukuba zilungele ukungasebenzi kakuhle kwii-vials ezinomgangatho, ukuqinisekisa ukusebenza okungaguqukiyo xa ujongile iisampulu.

I-crmimp vils ephezulu ye-vials: Ezinye ii-autosample zinokufumana i-crimps ephezulu ye-vials, kodwa ayizizo zonke iimodeli. Kubalulekile ukukhangela ubume bokuphepha imiba ngexesha lohlalutyo.

I-Snap ephezulu ye-vials: i-snap ephezulu ayisebenzi nazo zonke ii-autosamples njengoko zinganikezeli itywina elihle kwaye linokubangela ukuhanjiswa kwesampulu engahambelaniyo.

Olunye uqwalaselo

Zininzi ezinye izinto ekufuneka ziqwalasele ngaphandle kohlobo lwentamo xa ukhetha i-vial ye-entloko yohlalutyo lweVOC.

I-1. Iitywina

Izinto ezisetyenziselwa i-septum (inxalenye yenaliti) ingena kuyo) ibaluleke kakhulu.I-Silicone Septa zisetyenziswa ngokubanzi ngenxa yokungaxhathisi bazo kunye nokukwazi ukugcina itywina elihle kwiqondo lobushushu elithile. Qiniseka ukuba izinto zokutywina ziyahambelana ne-VOC ehlotyeweyo.

I-2. Umthamo we-vial

Umthamo wePayiphu ngaphezulu kwesampulu yetroli ibalulekile ekulinganeni okusebenzayo phakathi kwezigaba ezingamanzi kunye negesi. I-vials ezinkulu ngokubanzi zibonelela ngakumbi entloko, enyusa ubuntununtunu bokufumana iziqu eziguqukayo.

3. Uzinzo lobushushu

Olunye ukuqwalaselwa kukuba i-vial ingakwazi ukumelana nobushushu ngexesha lohlalutyo. Ezinye ii-VOC kufuneka zifuduselwe ngexesha lohlalutyo, ke i-vial vial kufuneka ikwazi ukugcina ukuthembeka kwayo phantsi kwezi meko ngaphandle kokuphulukana netywina okanye ukuvuya.

Ngolwazi oluthe kratya malunga ne-vials ye-autosampler ye-chromatography, ibhekisa kweli nqaku: I-2 ml automampler vials ye-chromatography yegesi

Isishwankathelo, ukhetho lwesampulu yomlomo we-vil yesampulu inefuthe elibonakalayo kuhlalutyo lweziqulatho zezinto eziphilayo nge-chromatography yerhasi. Izinto ezifana nentembeko yesampulu, ukulungiselela ukusetyenziswa kwesampulu, i-andesampler yokuhambelana, kunye nezinto zokutywina konke kudlala indima ebalulekileyo ekuqinisekiseni ukuchaneka kunye nokuthembeka kweziphumo.

Abaphandi kunye neengcali zelebhu kufuneka ziphonononge ngenyameko le miba xa ukhethaI-vials paicces yohlalutyo lweVOC. Ngokubeka phambili uyilo lwe-vial onokuthi luvalwe ngokuqinileyo, njenge-screw-cap-caps, i-vial-cap-cap inokunciphisa ukulahleka kwezinto eziguqukayo kunye nokuphucula ukusebenza kohlalutyo.
