Sept Sarudzo ye Autosamppler Vals

Septum yaunosarudza yakoautosampler vialinogona kukanganisa maitiro emuenzaniso kubuda, sampula yekuchengetedza, tsono inodarika uye yekuvhara, uye chiridzwa chekugara. Usarega kuoma kweSeptsa sarudzo kukudzikama.

Septa Selection chishandiso

Chishandiso cheSctle chekusarudza chinokurudzira kwazvo Septa yakanakisa nekupindura mibvunzo mishoma yakapusa, yakadai se:

1. Hplc, UHPLC, kana GC?

2. Screw tambo yezvipenga, Crimp Pamusoro Caps, uye Snap-It CAPS?

3. Autosampler Sindano Type & Tip Diameter?

4. Slit kana isiri-slit dhizaini?

5. Ridzai kugona?

6. Sol Solvent uye tembiricha iyo yeSista ichaoneswa?

7. Akawanda majekiseni?

Sept Sarudzo Muti

Chishandiso cheSctle chishandiso chinoshandisa chati pazasi kuti usarudze septum ichabatsira kudzivirira kusvibiswa uye kudzivirira kukuvara.

Pfungwa ina dzinokosha dzaunoda kufunga kana uchisarudzaSeka yakakodzera Septa:

1. Chiridzwa

Chiverengero chimwe nechimwe chinoshandisa jekiseni akasiyana emhando dzekushayiwa uye kune zvimwe zviridzwa, kana kusasarudza zvinhu nemhenderekedzo yezasi (kuomarara) kukosha kuchabatsira kudzikisira mikana yezvinhu zvetsiva, sekukotama.

2. Makomendi ekufarira

Kana makomputa ako ari kuwirirana saka kusarudza Septa iyo ichapa chisimbiso chakasimba ndeye kiyi yekudzivirira kurasikirwa kwakaringana. Yedu Yepamberi Yevhavha Yevhavha System (Avcs) Caps Bvisa Subjectivity Kutenderera Kukonzeresa Salimal Compression kana kuvhara vial.

3. Sol Solvent

Mamwe masosi anowanzo shandiswa kune HPLC, UHPLC, uye ECC Kwayedza inogona kukanganisa SEPTA kuvimbika.

4. Tembiricha

Kana iwe uchifanira kuisa iyo yakasarudzika yemuenzaniso mumagariro akakwira, iwe uchafanirwa kufunga nezveSeptta zvinhu zvinogona kutsungirira kupisa kwakanyanya.

Sept zvinhu& Zvivakwa

Septa anogadzirwa kubva kune akasiyana zvinhu. Ona pazasi kuti tsanangudzo uye kushandiswa kwemhando dzakasiyana dzeSept zvinhu.

Rubber Septa

Ivo vanoshandiswa zvakanyanya pakuongorora maitiro mune gasi chromatography. Inopa kugona zvine mwero kuti uwedzere uye yakanaka yemakemikari kana Isingakurudzirwe kujekesa kwakawanda kana kubata samples kuti uwedzere kuongorora. PTFE inzvimbo yekudzivirira yakambotyorwa kufumura rabara kurwiswa kwemakemikari.

PTFE \ / Red Rubber: Yakadzika Rubber Durometer inobvumira sindano. Chidimbu chakakurumbira uye chehupfumi chekare cheGeneral GC zvinangwa.

PTFE \ / Rubber: Yakaomesera giredhi yeRabha yekushandisa nekubaya sindano. Inonyanya kufarirwa uye yehupfumi Septa yeGeneral GC zvinangwa.

Pre-Slit PTFE \ / Red Rubber: Pre-slit, yakakwira-mhando tsvuku rabara neyekuonda (0.003 ")

Silicone Rubber Septa

Yakakwira-mhando, silicone rubber yakareruka kune ptfe. Shandisa apo hunhu hwakanakisa hwekuwedzera chinhu chinofanira. Septum inoramba kuora uye inokurudzirwa kana majekiseni akawanda anodikanwa. Inosarudza Septa yekushandisa mumvura chromatography application.

Ptfe \ / silicone: yakachena kwazvo silicone yakarongedzwa kune ptfe. Septum inoramba kuora uye inokurudzirwa kuti zviridzwa nematehwe akanaka emajinga. Zvakare yakakurudzirwa yeLC-ms uye GC-MS nekuda kwekunaka kwakanyanya.

PTFE \ / Silicone \ / ptfe: denderedzwa rePTFE pane rimwe nerimwe rutivi rwepakati pekuomarara. Yakanyanya kupokana kuenderana neyepamusoro-avhareji yekufananidza maitiro. Yakakurudzirwa kune inonyanya kudiwa application yakadai sekutevera kuongorora, nguva refu pakati pejekiseni, kana yemukati memukati. Shandisa chero autosampler uchishandisa yakakura dhayamu, isina-tip syringe madhiri.

Pre-Slit PTFE \ / Silicone: Pre-slit, yakakwirira-mhando yakachena chena silicone yakatarisana ne ptfe. Zvekushandisa uchishandisa yakaonda-gage syringe sindano kana mune zviitiko kana acuum inogona kuumba mune vial.

Ptfe uye fluoropolysmers

Yakanaka kwazvo yemakemikari kuramba uye inoshandiswa seyakadzivirira denderedzwa revashoma vanopesana elastomers.

Butyl Rubber \ / ChloroButyl Rubber

Chisarudzo chehupfumi chekushambadzira kwakaderera (<125 ° C) kana kuderera-kudzvinyirira mafomu. Haina kukodzera kune alkanes, benzene, chlorinated sol sol molents kana cyclohexane isina ptfe inodzivirira.

Silicone Rubber

Yakanakisa Sept Sarudzo yekusavimbika ine yakanyanya kusimuka kumashure mapepa uye kuderera kwekufungidzira. Zvakare zvakanaka kune alcohols uye mahure emvura. Yakanaka yekuongorora maitiro uye kuramba kuora.

Natural ptfe \ / blue silicone: yakanakisa Septa sarudzo kana tembiricha inopfuura 125 ° C.

Natural ptfe \ / tsvuku silicone: yakakwira tembiricha yakasimbiswa chisimbiso neine yakaderera kubuda ropa. Sarudzo yeSepta yakanakisa kana tembiricha iri kusvika mazana matatu ° c.

Blue Silicone \ / Red PTFE: Zvakaoma 1.4 mm Chisimbiso nePTFE CHETE. Kuongorora kwehukuru kune mashoma nekuda kweiyo yakatetepa silicone layer.

Aluminium \ / chena silicone: inoratidza aluminium kumeso inodzivirira chisimbiso cheSilitone. Iyo chena silicone yakakodzera kushandiswa kusvika pa150 ° c.

Aluminium \ / Red Silicone: inoratidza aluminium kumeso inodzivirira chisimbiso cheSilitone. Iyo tsvuku silicone yakakodzera kushandiswa pakupisa kusvika ku25 ° c.

Blue Silicone \ / Yakasikwa PTFE: Silcone silicone ine yakachena fomu yekukanganisa kushoma. Zvisimbiso zvevatengi zvakakodzera kuti solvent kugeza, solvent kubviswa, uye yakasimba chikamu microextraccary (spme) zvikumbiro pamwe nezvimwe zvakafanana. Kwete kune zvakananga mumusoro mashandisirwo.

Mhedziso

Dzimwe pfungwa pamusoro peSepta sarudzo inoda yako pamwe. Saka sarudzo dzakawanda nezve sarudzo yekusarudzwa kweSchsa inogamuchirwa.
