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

Ekuhlolweni kwezemvelo okunomthamo ophezulu, ukuphepha kokudla, nobuthi, izinhlanganisela eziyinkimbinkimbi eziqukethe ama-lipid angaguquki, imibala, nezinhlayiya ezisindayo zingcolisa ngokushesha ingxenye yokungenisa yamakholomu e-capillary GC. Lokhu kungcoliswa kubangela ukudonsa kwesiqongo, ukwakheka kwezindawo ezisebenzayo, nokukhukhula kwe-baseline, okuphoqa abahlaziyi ukuthi banqume amakholomu njalo, okunciphisa impilo yekholomu yokuhlaziya futhi kukhuphule izabelo zezinto ezisetshenziswayo.
I-GC capillary column inlet ingcoliswe ama-lipids angavuthiwe, ama-pigments, nezinhlayiya ezibangela ukudonsa kwe-peak

Okubalulekile Okutholakele

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

Kungani I-Matrices Eziyinkimbinkimbi Zicekela Phansi Amakholomu Okuhlaziya

Ukujova Kwe-Matrix Eyinkimbinkimbi (Amafutha/Imibala) ➔ Izinto Ezingaguquki Zifakwa Esigabeni ➔ Ukuwohloka Kwesigaba Esimile ➔ Ukugoba Kwe-Peak Nokushintsha Kwezikhathi Zokugcina ➔ Ukuphoqeleka Ukunciphisa Ikholomu
Umdwebo wokugeleza wenqubo yokucekelwa phansi kwekholomu ye-GC kusukela ekujoveni kwe-matrix kuya ekunqunyweni kwekholomu okuphoqelekile
  1. Ukungcola Kwesigaba Esimile:
  2. Ukudalwa Kwesiza Esisebenzayo:
  3. Ukuhlukaniswa Kwezakhi:

I-ROI Yokufaka Ikolomu Yokuqapha Engasebenzi

Ikolomu lokuhlaziya elijwayelekile elingu-30 m × 0.25 mm ID × 0.25 µm libiza 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 Kwekolomu 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- guard tubing edelayo
Ukuzinza Kwesikhathi Sokugcinwa
Kushintsha njalo lapho kunqunywa
Kuhlala kuzinzile kukholomu yokuhlaziya
Umthwalo Wokuqinisekisa Kabusha Indlela
Phezulu (kudingeka ukulungiswa kwe-RT calibration)
Kuncane (ivolumu ye-void ihlala ifana)
Izindleko Zonyaka Zokushintsha Ikolomu

Kwehliswa kufinyelele ku-40%–50%

Ukukhetha Ikolomu Yokuqapha Efanele Nokubhangqa Kwekolomu Yokuhlaziya

Ukuze ugweme ukunwebeka kwe-peak noma ukungahambisani kwezigaba, ububanzi bangaphakathi boshubhu lokuqapha kanye nokungasebenzi kwamakhemikhali kufanele kuhambisane nokuhleleka kokuhlaziya.

  • I-Chemistry Yobuso Bokungasebenzi:
  • Izixhumanisi Ezingenayo I-Dead-Volume:

Amakholomu e-CHANCEPRO GC kanye Nezinto Ezisetshenziswayo Ezivikelayo

Yakhelwe ukufana namazinga omkhakha wamazwe ngamazwe (ilingana ne-DB-5ms, i-HP-5ms, ne-Rxi-5ms):
  • I-CHANCEPRO High-Inertness Deactivated Guard Tubing:
