I-chromatography ewuketshezi Insimbi engagqwali i-capillary chromasir

Kunezinhlobo ezintathu zensimbi engagqwali capillary: Traline capillary, Ribend capillary kanye Supline capillary. Wonke ama-capillary athatha insimbi engagqwali engu-316L njengempahla, enobubanzi obungu-1.58mm (1/16inch) obungaphandle kuzo zombili iziphetho, 0.79mm (1/32inch) ububanzi obungaphandle phakathi nendawo. I-Traline stainless steel capillary ijwayele ukutsheka, futhi imelana kahle ne-1200bar kanye ne-acid-base. Zombili iziphetho ze-Ribend capillary zenzelwe ukuthi zibe pliant, ezivimbela ukuthi zinganqamuki. Imelana ne-1200bar kanye ne-acid-base kahle. Uma kuqhathaniswa nochungechunge lwe-Traline, i-Ribend inokuphila okude, nokungalungi okungasetshenziswa kuphela ekufakweni kwensimbi okufushane okufanayo. Zombili iziphetho ze-Supline capillary ziklanywe ngelungelo lobunikazi "lomumo" wesigubhu; okungukuthi i-capillary ilayishwe i-gasket yokuvala, ngemva kokuqinisa iminwe, ukuvala uphawu kabili kwezindiza nezinhlangothi kungafinyelelwa. I-capillary ijwayele ukugoqa, okuvimbela ukuphuka. Ingamelana ngaphezu kwe-1200bar, kanye ne-acid-base. I-capillary kanye nokufaka kungahlukaniswa futhi kufakwe esikhundleni sodwa, ukuphila kuze kufike izikhathi ezingu-150 (kwibhantshi lekholomu yokungenisa kanye nedivayisi). Uma kuqhathaniswa nochungechunge lwe-Traline ne-Ribend, uchungechunge lwe-Supline lungafinyelela ukusebenza kokuvala kabili, lusebenze kuzo zonke izinhlobo zamakholomu e-chromatographic, futhi lunciphise ivolumu efile yokuxhumana ye-capillary.

Ukufakwa kwensimbi engagqwali okuqinisa umunwe ku-capillary kulula ukukusebenzisa futhi kufakwe ngokushesha ngaphandle kwanoma yimaphi amathuluzi, noma kusetshenziswe kumakholomu echromatographic athuthuke kakhulu kanye nokulungiswa kwama-valve ashintshayo. Ukufakwa kwe-capillary kuhambisana namakholomu namavalvu avamile e-chromatographic, futhi imelana nokucindezela kwesistimu okufika kumabha angu-400.
