Septa Kusankha kwa Autosambir

Septum yomwe mumasankha yanuAutosambirr Vialimatha kusintha zitsanzo za kusintha, chitetezo chachitsanzo, singano ndi zotchinga, komanso chida. Musalole zovuta za septa kusankhidwa kukuchepetsa.

Chida chosankha

Chida cha Septa chimalimbikitsa Septa yabwino kwambiri poyankha mafunso ochepa, monga:

1. HPLC, UHPLC, kapena GC?

2. Screw showr zisoti, zigamba zapamwamba zazikulu, ndi kugwadira?

3. Autosambler Studle Mtundu & Wegmer Weameter?

4. Slit kapena zopanda pake?

5. Kuthekera?

6. Ma sol sol sol sol the Septa adzadziwitsidwa?

7. Jakisoni angapo?

Mtengo wa SEPA

Chida chosankha cha Septa chimagwiritsa ntchito tchati pansipa kuti asankhe septum yomwe ingathandize kupewa kuipitsidwa ndikupewa kuwonongeka.

Mfundo zinayi zofunika kuzilingalira posankhaSepta yoyenera:

1. Chida

Wogulitsa aliyense amagwiritsa ntchito mitundu yosiyanasiyana ya invorcar ndi zida zina, ndikusankha zigawo za slit, kapena kusankha zinthu zomwe zili ndi m'mphepete mwa nyanja zamagetsi, monga singano.

2. Zisankho za chidwi

Ngati mankhwala anu akugwiritsa ntchito mosamala kenako ndikusankha SePA yomwe ingapereke chidindo cholimba ndi chinsinsi choletsa kutaya. Mapulogalamu athu apamwamba atsekedwa (ma avcs) zochotsa zomwe zikuchitika pokwaniritsa chidindo chokwanira potseka vial.

3.

Zina zofananira zomwe zimagwiritsidwa ntchito nthawi zambiri kwa HPLC, UHPLC, ndi GC imasokoneza kukhulupirika kwa SePTTA.

4. Kutentha

Ngati mukufuna kuyika vuli yokhometsedwa bwino m'malo otentha kwambiri, muyenera kuganizira zida za Septa zomwe zimatha kupirira kutentha kwambiri.

Zipangizo za Septa& Katundu

Septa amapangidwa kuchokera kuzinthu zosiyanasiyana. Onani pansipa kuti matanthauzidwe ndi mitundu yosiyanasiyana ya zida za septa.

SePta ya mphira

Amagwiritsidwa ntchito makamaka pakusanthula kwa ma chromatography. Imapereka kuthekera kotheratu kokhazikika komanso kusiyanasiyana kwa mankhwala. Osavomerezeka kuti jakisoni angapo kapena azigwira zitsanzo zowunikiranso. Ptfe ndi chotetezera chomwe chidasweka chimawulula mphira kuti chiwombedwe cha mankhwala.

PTFF \ / mphira wofiira: duumeter yotsika mphira imalola kulowa kwa singano. Septum yotchuka komanso yachuma kwa General Gec.

PTFF \ / mphira: kalasi yovuta ya mphira wogwiritsira ntchito ndi singano yoboola. Septa wotchuka kwambiri komanso wachuma wa General GC.

Pre-slit ptfe \ / mphira wofiira: Pre-rait, mphira wowoneka bwino wokhala ndi wowonda (0,003 ") wosanjikiza wa PTF. Zogwiritsa ntchito singano yoonda kwambiri kapena nthawi yomwe vacuum ikhoza kupanga vial.

Silicone mphira septa

Mtengo wapamwamba kwambiri, wa silicone walemba ptfe. Gwiritsani ntchito zinthu zabwino kwambiri zomwe zingasinthe. Septum imaletsa kuvala ndikulimbikitsidwa pomwe jakisoni angapo amafunikira. Amakonda Septa kuti agwiritse ntchito mu madzi a chromatography.

PTFF \ / Silicone: silicone yofewa kwambiri yofewa ku PTF. Septum imaletsa kutchinga ndipo tikulimbikitsidwa chifukwa cha zida zokhala ndi singano zabwino za geagege. Ndinalimbikitsanso LC-MS ndi GC-MS chifukwa cha chiyero chachikulu.

PTFF \ / sticone \ / ptfe: wosanjikiza wa ptfe mbali iliyonse ya sisili silicine. Kugonjetsedwa kwambiri ndikugwirizanitsa ndi mawonekedwe apamwamba obwereza. Analimbikitsanso ntchito zofunitsa zomwe zimasanthula monga kusanthula kwanthawi yayitali, nthawi yayitali pakati pa jakisoni, kapena miyeso yamkati. Gwiritsani ntchito autosample iliyonse pogwiritsa ntchito mainchesi akuluakulu, ntchentche ya blunt.

Pre-slit ptfe \ / silicone: Pre-slit, silika wapamwamba kwambiri wonyezimira wa PTF. Zogwiritsa ntchito pogwiritsa ntchito singano yoonda kwambiri kapena nthawi zina ngati vacuum ikhoza kupanga vial.

Ptfe ndi fluoropolymers

Zabwino kwambiri kukana mankhwala ndikugwiritsa ntchito ngati malo otetezera osagwirizana ndi ma elastomers osagonjetseka.

Butyl mphira \ / chlorobutyl rabara

Chisankho chachuma kutentha kwa kutentha (<125 ° C) kapena ntchito zotsika kwambiri. Osayenera ma Alkanes, benzene, chlorinated sol sol kapena cyclohexane popanda choteteza porter.

Silika rabar

Kusankha Kwambiri Septa kwa osinthika ndi nsonga zochepa kwambiri. Komanso zabwino za mowa ndi zitsanzo zam'madzi. Zabwino zobweretsa mawonekedwe ndi kukana kupangira.

Zachilengedwe Ptfe \ / silika wabuluu: Njira yabwino kwambiri Septa pomwe kutentha kuli zoposa 125 ° C.

Zachilengedwe ptfe \ / silika wofiyira: Kutentha kwakukulu kopangidwa chisindikizo ndi magazi pang'ono. Chisankho chabwino kwambiri septa pamene kutentha kuli 300 ° C.

Blue silicone \ / chofiira cha PTF: Kugonda 1.4 mm ndi nkhope ya PTF. Kuyambiranso kuthekera kumakhala kochepa chifukwa cha speinner siketi.

Aluminium \ / silika yoyera: nkhope yowonetsera aluminium imateteza chisindikizo cha siloyi. Silicone yoyera ndiyoyenera kugwiritsidwa ntchito mpaka 170 ° C.

Aluminium \ / silika wofiyira: nkhope yowonetsera aluminium imateteza chisindikizo cha siloyi. Silika wofiira ndi woyenera kugwiritsa ntchito kutentha mpaka 250 ° C.

Slika ya buluu \ / chilengedwe cha ptfe: Silicone yofewa yokhala ndi mawonekedwe oyera osokoneza bongo. Zisindikizo zongana ndizoyenera kutsuka, zosungunulira zosungunulira, ndi gawo lolimba la microectraction (spme) zogwirira ntchito ndi zina zofananira. Osati zowongolera zowongolera.

Mapeto

Malingaliro ena okhudza Septa kusankha amafunika kuphatikiza. Zosankhidwa zina zokhudza Septa kusankha zimalandiridwa.
