I-pre-slit ptfe \ / isiliki septa

Ufuna ukwazi ulwazi olupheleleyo malunga ne-ptfe \ / isilicone Septa, nceda ujonge eli nqaku: Yonke into oyifunayo

Yintoni i-pre-slit septa?

I-Slit yangaphambi kokuba ivalwe i-vial i-villa ivumela i-slit eyenziwe kwangaphambili evumela ukungena ngokulula kwiinaliti ezisetyenziswa kwi-autosamplers. Eli nqaku loyilo liluncedo ngokukhethekileyo kwii-labs ezifuna ukuphinda ziphile kwakhona okanye ziyikhuphe kwi-vial vial. I-Pre-slit septa isuse inaliti evaliweyo emva kwesampulu. I-slit ivumela inaliti ukuba ifikelele kwisampulu ngaphandle kokwenza isiphungulo esitsha ngexesha ngalinye, elinceda ukugcina ingqibelelo yetyheli yetywina.

I-pre-slit ptfe \ / isiliki septa zidityaniswe ngezinto ezimbini eziphambili:

I-ptfele Famite: Lo mahluko unika ukungavisisani kweekhemikhali zekhemikhali, ekhutshiwe, kunye nobuncinci bokuphambuka. I-PTFE yaziwa ngokuba yi-Interter yayo, iyenza ilungele uluhlu olubanzi lweenyibiliki kunye neekhemikhali ezisetyenziswa rhoqo kwi-chemistry yohlalutyo.

I-Silicone Father: Icandelo le-silicone lisongeza amandla kunye nokuqina kwiSeptum. Iphucula ukukwazi ukutshatiswa kwakhona emva kokuxhwilwa kwenaliti, ukuqinisekisa ukuba iisampulu zikhuselwe kungcoliseko kunye nokuphuma.

Ukudityaniswa kwezi zinto kuvelisa iSeptum enokubonisa ukubopha izinto okuphinde nokugcina itywina elinokuthenjwa.

Izibonelelo zeSepta Pal

I-1. I-Pre-Slit Septa yenza lula inkqubo yesampulu. Izilayidi zaphambi kwezilwanyana zivumela iinaliti ezifanelekileyo ukuba zingene ngokulula ngakumbi, ukunciphisa amandla afunekayo ukuze afune iSeptum. Eli nqaku liyingenelo ikakhulu kwiinkqubo ezenzekelayo apho isantya kunye nokusebenza kakuhle kubalulekile.

2. Inzuzo ephambili ye-pre-slit septa kukukwazi kwabo ukunciphisa ukugoba inaliti ngexesha lokukhupha isampula. Ukusikwa kubonelela ngendawo yokungena engapheliyo yenaliti, enceda ukugcina ulungelelwaniso kunye nokunciphisa umahluko kwii-antles zenaliti. Olu phawu loyilo luyekelela amathuba omonakalo we-nenale, ngaloo ndlela ukuphepha ungcoliseko okanye imiqulu engahambelaniyo.

3. Umaleko we-silicone uphucula ubuchule bokungenela emva kwenaliti. Eli nqaku libalulekile kwizicelo ezifuna inaliti ezininzi ukusuka kwi-vial ye-vial, njengoko inceda ukugcina itywina eliqinileyo, ukuthintela isampulu yesampulu kunye nongcoliseko phakathi kwenaliti.

I-4. Ukusika kwangaphambili i-Septa ibonelela ngomoya ogqwesileyo wokuthintela ukwenziwa kwe-vacuum ngaphakathi kwesampulu i-vial vial, ngaloo ndlela ifezekisa ukuzala okugcweleyo. I-Pre-capta ye-Pepta ingakhuthaziswa ngempumelelo uxinzelelo lwe-valoum kwinaliti enkulu. Eli nqaku lithintela iingxaki ezinokubakho ezinxulumene nokuqokelelwa koxinzelelo ngaphakathi kwe-vial, ngaloo ndlela zikuphepha ilahleko okanye ungcoliseko.

I-5. Isiki se-Pepta sihambelana neentlobo ezahlukeneyo zeSilobi se-Automamples, kubandakanya ezo zenziwe ngentsimbi kunye ne-Peek (Polyenetonetone). Okuhluziweyo kuvumela iilebhu zokukhetha amarisithi ngokusekwe kwiimfuno zabo ezithile ngaphandle kokukhathazeka malunga nemicimbi yokuhambelana.

Ukuthelekisa kunye ne-septa engeyiyo i-septa

Ngelixa uSepta wangaphambi kokuba uSepta uneengenelo ezininzi, i-septa engeyiyo i-septa zisetyenziswa rhoqo kwiindawo zelebhu.

I-PATA YOKUGQIBELA

Ukugcinwa kwexesha elide: EngafakwangaI-Septa inokusetyenziselwa inaliti ezininzi kunye nokugcinwa kwesampulu. Ezi ziqwenga zihlala zicetyiswa ukuba zigcinwe ixesha elide kwiisampulu kuba zinokugcina itywina elinzima xa lingasebenzi.

Ukukhuselwa kwi-Evaporation: Engafakwanga I-Septa inika ukhuseleko olungcono ekunikezelweni ngaphambi kokuba lihlatywe, libenze balungele iisampulu eziguqukayo ezinokuthi zikhuphe ngokukhawuleza.

Ngaba ufuna ukwazi ukuba ukhetha i-septa kwi-pre-slit okanye hayi? Nceda ujonge eli nqaku: Ungayikhetha njani i-Septa Pal-Slit okanye hayi?

Ukuqwalaselwa xa ukhetha iSepta

Xa ukhetha phakathi kwe-Pal-Slit kunye ne-Slit Septa, kukho izinto ezininzi ekufuneka ziqwalaselwe:

1. Uhlobo lwesampulu yesampulu iya kuhlaziywa luya kuba nefuthe ekukhetheni izinto zeSeptum. Umzekelo, ukuba izinyibilikisi ezibonakalayo kakhulu okanye izinto ezisebenzayo ziyasetyenziswa, ukuqinisekisa ukuhambelana ne-PTFE kunye ne-Siliconees zigxeka.

2. Ukuba usampulu okanye uhlalutyi i-vials amaxesha amaninzi, i-plit plit septa ibonelela ngokulula kunye nokusebenza kakuhle. Ngokuchaseneyo, i-septa engeyiyo i-septa inokulunga ngakumbi ukuba kugcinwe ixesha elide kuyafuneka kwaye ufikelelo lungaphantsi.

3. Ukukhetha inaliti yesampulu kuya kuba nefuthe kwisigqibo. I-Pre-Slit Septa ilungele iinaliti ezicekeceke, ngelixa i-septa engeyiyo i-SPTA inokuthathwa ngcono kwiinaliti ezifunelwa yitywina elifuna ukuba litywina.

4. I-Pre-capta Ngaba uluhlu lwamaqondo obushushu osebenza nge-40 ° C ukuya kwi-200 ° C; kakhului-sls I-ptfe \ / Isiliki septa inokumelana namaqondo obushushu ukuya kuthi ga kwi-200 ° C, kodwa angahluka ngokuxhomekeke ekuqulunqweni.

Izicelo zeSepta yangaphambi kweSepta

I-Pre-Sild Septa isetyenziswe ngokubanzi kwizicelo ezahlukeneyo kuhlalutyo lwe-chemistry:

Uhlalutyo lokusingqongileyo: Ukuhlolwa kwendalo: Ukuhlolwa kwendalo, iisampulu kufuneka zikhutshwe rhoqo kwii-vils ezinee-orting eziqukethe iziko lezinto eziphilayo (VOCs), kwaye ukusika kwangaphambili iSeptTa kuququzelela isampulu ekhawulezayo.

Ukuvavanywa kwamachiza amachiza: kwiilebhu zamachiza apho kufuneka inaliti kwaye ineenaliti eziphindaphindiweyo ziyafuneka, ezi Septa ziphucule ukuphindaphinda kwaye zinciphise ungcoliseko lomnqamlezo.

Uvavanyo lokutya lokutya: Kulondolozo lohlalutyo lokutya apho imithanga ye-volatile kufuneka ibekwe esweni ngokusondeleyo, ngaphambi kwexeshai-sls I-Septa yenza ukuba isampulu esebenzayo ngaphandle kokulalanisa kwingqibelelo yesampulu.

Ufuna ukwazi ulwazi olupheleleyo malunga ne-ptfe \ / isilicone Septa, nceda ujonge eli nqaku:Ipremiyamu ptfe kunye ne-silicone Septa: Iziko elinokuthenjwa

Ngaphambi kwexeshai-sls Ptfe \ / isilicone Septa zizinto ezibalulekileyo kwiilebhu zanamhlanje zohlalutyo zisebenzisa i-chromatography yegesi kunye neendlela zobunzima be-shoctrometry. Zenzelwa ukuba zikhululwe ukusetyenziswa, ukuphuculwa kokuzala, ukucutha imiba enxulumene nenaliti, kwaye isebenze kwiimeko eziphezulu zokungena. Ukudibanisa ukunganyangeki kwekhemikhali kwe-ptfe ngesifo se-silicone, ezi ziSepta zibonelela ngesisombululo esisebenzayo sokugcina ingqibelelo yesampulu kwizicelo ezahlukeneyo zohlalutyo. Ngokuqonda izibonelelo kunye nokusikelwa umda kwendlela nganye, abahlalutyi zinokuqinisekisa ukuba ukhetho lwabo luya kuxhasa iziphumo ezichanekileyo zomsebenzi wovavanyo.
