Ulwazi olulula lwama-chromatographic vials

Ukuhlaziywa kwe-chromatographic kuyindlela yokuhlukanisa nokuhlaziya izingxube eziningi zezakhi. Isebenzisa ikakhulukazi umehluko endaweni ebilayo, ama-polarity kanye nokuhlanganiswa kwengxenye ngayinye kwisampula, ukuze izakhi zihlukaniswe kwikholamu, futhi izingxenye ezihlukanisiwe zitholwa umtshina, ukuze inhlanganisela yengxenye itholwe ngaphansi kokuhlaziywa kwengxenye.

Ngenxa yokusebenza kwayo okuphezulu okuphezulu, ijubane lokuhlaziya ngokushesha kanye nokusetshenziswa kwesampula okuphansi, indlela yokuhlaziya isetshenziswe kabanzi ku-petrochemical, i-biochemical, ukuvikelwa kwezemvelo, imboni yokudla, imboni yokudla, umnyango wezokwelapha, umnyango wezokwelapha, umnyango wezokwelapha, njll. Umnyango. I-Gher Chromatography ixazulula izinkinga ezinjengokuhlolwa kwekhwalithi, ucwaningo lwesayensi, ukutholwa kokungcoliswa, kanye nokulawulwa kokukhiqizwa kwemisebenzi ekhiqizwe izimboni kanye nemikhiqizo yezimboni kule mikhiqizo yezimboni kule mikhiqizo yezezimboni kule mikhiqizo yezimboni.

1) Ulwazi oluyisisekelo mayelana nama-vials:
Izidingo ze-vial zinembile, zingamelana nengcindezi ethile, ukusebenza kahle kokubekwa uphawu, futhi akukho ama-adsorpl kusampula. Ofanele kufanele akhethwe ngokuya ngezidingo zensimbi kanye nesimo sesampula. I-Seating Cap: Ukuze uvikele i-gasket kusuka ku-adderbing izingxenye zesampula, i-gasket ene-PTFE noma i-aluminium langaphakathi liyasetshenziswa. Izimo zokukhetha (lokushisa) kanye nemibandela ethile yesampula incike kwisampula. Ukuhlaziywa kwendlela evamile kungenziwa nge-butyl rubber mat kanye nomugqa we-silicone rubber mats wokuhlaziywa kwe-trace. Uma kunesidingo, ukuhlaziya okungenalutho kwenziwa ukuqinisekisa ukuthi ama-volutiles e-gasket awaphazamisi ukuhlaziywa.

2) Mayelana nokuthi ungakhetha kanjani i-vial eyisampula
Okokuqala, kudingeka siqonde ukuthi ama-vials ikakhulukazi ama-Jaw cap vials, ama-vials ane-cap cap kanye ne-bayonet caps.
Uma ufuna uhlobo lwenhloso ejwayelekile kanye ne-acid, ungakhetha ibhodlela lesampula yengilazi;
Uma isetshenziselwa imiqulu emincane kakhulu yomjovo, kudingeka ilinguni elincane elingaphakathi;
I-Sawaneization \ deactivation iyadingeka uma isetshenziselwa amasampula nokuhlaziywa kwe-TRACE okuboshwe kalula odongeni lwebhodlela lengilazi;
Uma isetshenziselwa amasampula athambile akhanyayo, kudingeka ibhodlela elinsundu;
Uma isetshenziselwa amasampula e-Alcohol noma ama-soluble ancibilikayo, i-polypropylene iyadingeka.

3) Ukusuka ekuhlanzeni ibhodlela lesampula
Eqinisweni, lapho senza i-chromatography ewuketshezi,HPLC VIALSkukodwa, kepha izindleko ziphezulu kakhulu, ngakho-ke manje sidinga ukusebenzisa i-vial ephindaphindwayo, kufanele sihlanzeke kangcono. Singazama ukusebenzisa ama-reagents ezi-organic ukuze ahlanze. I-Ethanol ingasetshenziselwa ukuhlanza. Uma isetshenziswa ngokuphuthumayo, ingagezwa nge-ethanol bese iqhuma yomile nge-soryer yezinwele.
