Izinsika Zokuvikela Zinciphisa Izindleko Zokushintsha Kwekholomu Ye-GC Yokuhlaziya Ngamaphesenti angu-40

Ekuhlolweni kwezemvelo okunomthamo omkhulu, ukuphepha kokudla, kanye nobuthi, izinhlanganisela eziyinkimbinkimbi eziqukethe ama-lipid angaguquki, ama-pigment, nezinhlayiya ezisindayo zingcolisa ngokushesha ingxenye yokungenisa yamakholomu e-capillary GC. Lokhu kungcola kubangela ukudonsa kwe-peak, ukwakheka kwezindawo ezisebenzayo, nokukhukhuleka kwe-baseline, okuphoqa abahlaziyi ukuthi banqume amakholomu njalo, okunciphisa impilo yekholomu yokuhlaziya futhi kukhuphule izabelo zezinto ezisetshenziswayo.
Ikolomu yekholomu ye-GC ingena ngokungcola okungavuthiwe okungamafutha, imibala, nezinhlayiya ezincane ezibangela ukwehla kweqophelo lephiko

Amaphuzu Abalulekile

  • Imbangela Eyinhloko Yokonakala Kwekholomu:
  • Izindleko Eziphezulu Zokunciphisa Njalonjalo:
  • Ukulungiswa Kwezobuchwepheshe: i-guard column enganyakazi enezinga lokushisa eliphezulu (retention gap)

Kungani I-Matrices Eziyinkimbinkimbi Zicekela Phansi Amakholomu Okuhlaziya

Ukujova Kwe-Matrix Eyinkimbinkimbi (Amafutha/Imibala) ➔ Okungaguquki Kufakwa Esigabeni ➔ Ukuwohloka Kwesigaba Esimile ➔ Ukugoba Kwe-Peak Nokushintsha Kwezikhathi Zokugcina ➔ Ukuphoqeleka Ukunciphisa Ikholomu
Umdwebo wokugeleza kwenqubo yokonakala kwekholomu ye-GC kusukela ekujoveni kwe-matrix kuya ekunqanyulweni kwekholomu okuphoqelekile
  1. Ukungcola Kwesigaba Esimile:
  2. Ukudalwa Kwezindawo Ezisebenzayo:
  3. Ukuhlukaniswa Kwezinto Ezihlanganisiwe:

Inzuzo Yokufaka Ikholomu Yokuqapha Engasebenzi

Ikholomu yokuhlaziya evamile engu-30 m × 0.25 mm ID × 0.25 µm ibiza kakhulu kune-shubhu yokuqapha ye-fused silica engasebenzi engu-5–10 m.
Ukuqhathanisa kwekholomu yokuvikela nokujova okuqondile okukhombisa ukuvikelwa kwekholomu yokuhlaziya kanye nokonga kwezindleko okungamaphesenti angama-40
Isilinganiso Sokusebenza
Ngaphandle Kwekholomu Yokuqapha (Ukujova Okuqondile)
Nge-CHANCEPRO Deactivated Guard Column (5m)
Isikhathi Esijwayelekile Sokuphila Kwekholomu Yokuhlaziya
Imijovo engu-200–400 yezinhlanganisela ezingcolile
Imijovo engu-800–1,200+
Isenzo Sokugcina
Nciphisa u-10–20 cm esigabeni sokuhlaziya
Nciphisa noma ushintshe kuphela i-sacrificial guard tubing
Ukuzinza Kwesikhathi Sokugcinwa
Kushintsha njalo ngokunquma ngakunye
Kuhlala kuzinzile kukholomu yokuhlaziya
Umthwalo Wokuqinisekisa Kabusha Indlela
Phezulu (kudingeka ukubuyekezwa kokulinganisa kwe-RT)
Kuncane (ivolumu engenalutho ihlala ingaguquki)
Izindleko Zonyaka Zokushintsha Ikholomu
Isisekelo (100%)
Kuncishiswa kufinyelele ku-40%–50%

Ukukhetha Ukuhlanganiswa Okufanele Kwekholomu Yokuqapha Nekholomu Yokuhlaziya

Ukuze ugweme ukunwebeka kwe-peak noma ukungahambisani kwesigaba, ububanzi bangaphakathi boshubhu lokuqapha kanye nokungasebenzi kwamakhemikhali kufanele kuhambisane nokuhleleka kokuhlaziya.
  • Ukufanisa Ububanzi Bekholomu:
  • Ukungasebenzi Kwe-Surface Chemistry:
  • Izixhumanisi Ezingenayo I-Dead-Volume:

Amakholomu e-CHANCEPRO GC kanye Nezinto Ezisetshenziswayo Ezivikelayo

Yakhelwe ukufana namazinga omkhakha wamazwe ngamazwe (ilingana ne-DB-5ms, HP-5ms, ne-Rxi-5ms):
  • I-CHANCEPRO High-Inertness Deactivated Guard Tubing:
  • Amakholomu e-CHANCEPRO -5MS Low-Bleed Capillary:
  • Izixhumanisi Ezijwayelekile Ezi-Press-Tight Ne-Inert Union:
