Ukuqeda Ukwehliswa Kwe-Active Site Nokwehla Kwe-Peak Tailing Kwezibulala-zinambuzane Ezi-Polar ku-GC/GC-MS

Ekuhlolweni kokuhlola izinsalela zemithi yokubulala izinambuzane (isb., organophosphorus, organochlorines) kanye ne-forensic toxicology workflows, ama-polar analytes afana ne-methamidophos, i-acephate, i-pentachlorophenol, ne-endrin avame ukuhlushwa ukwehla okukhulu kwe-peak tailing, ukwehla kwezinto zokuphendula, noma ukulahleka okuphelele kwesignali. Lokhu konakala kubangelwa ama-silanol active sites () aveziwe kuma-inlet liners nasenhlokweni ye-capillary column.
I-GC-MS chromatogram ekhombisa ukwehla okukhulu kwe-peak tailing ye-polar pesticide i-methamidophos ekuhlaziyweni kwe-trace residue

Amaphuzu Abalulekile

  • Indlela Yokulahleka Kwesignali:
  • Kungani Ama-Liners Avamile Ehluleka Ngokushesha:
  • Isixazululo Esiphelele: I-Chemical Vapor Deposition (CVD) high-density deactivated inlet liners kanye ne-ultra-inert guard column

Indlela Ama-Active Sites Aphazamisa Ngayo Ukuhlaziywa Kwezinsalela Zemithi Yezinambuzane

Ukujova Kwe-Dirty Matrix ➔ I-Thermal Pyrolysis Ku-Inlet ➔ Ama-Silanol (Si-OH) Aveziwe ➔ Ukubola Okubangelwa I-Catalyst Nokuhlanganiswa Kwe-Hydrogen ➔ I-Peak Tailing Enzima Nokulahlekelwa Ukutholakala (Methamidophos / Endrin)
Izindawo ze-silanol ezisebenzayo ku-GC inlet liner ezibangela ukukhanga kwe-hydrogen bonding kanye nokwehliswa kwe-catalytic kwama-pesticides ama-polar
  1. Ukuhlanganiswa Kwe-Hydrogen Bonding Adsorption:
  2. Ukubola Kwe-Thermal & Catalytic Decomposition:
  3. Ukungalingani Kokusebenza Kwe-Dual-Polarity Passivation:

Ukuqhathanisa Ukusebenza: Ama-Liner Ajwayelekile vs. Ukungasebenzi Kwe-CHANCEPRO Ultra-Inert

Ipharamitha Yokusebenza
Ama-Liner / Ama-Guard Ajwayelekile Ezohwebo
Inkomba Yezimboni (Agilent UI / Restek Topaz)
I-CHANCEPRO Ultra-Inert CVD Series
Inqubo Yokungasebenzi
Ukucwiliswa/ukuhlanza ngesigaba soketshezi
Isigaba segesi esishisayo
I-Chemical Vapor Deposition (CVD) Enobuningi Obuphezulu
Iphrofayela Yokungasebenzi Kwendawo
Okulinganiselayo (kuthambekele ekudonseni izisekelo)
Okungasebenzi ngokubanzi
Ukuvikelwa kokungathathi hlangothi kwe-Dual-Polarity (i-asidi nesisekelo)
Isici sokudonsa (
) se-Methamidophos
(noma isiqongo esilahlekile)

Ukuphuka kwe-Endrin / DDT
(yehluleka ukulawula ikhwalithi ngemva kokugijima okungu-30)
​
(kuqinisekiswe phezu kokugijima okungaphezu kwe-100 kwe-matrix)
Umbundu wokuzinza kokushisa

Inketho yoboya be-Inlet Liner
Okungalungisiwe / ukufakwa okuxekile
Uboya obulungisiwe be-Ultra-inert
Uboya be-CVD Deactivated Fused Quartz (In-Situ)

Izinqubo ezi-4 zokugcina ukungathathi hlangothi kohlelo ekugijimeni kwezinsalela eziningi

  1. Sebenzisa i-Guard Column engathathi hlangothi kakhulu:
  2. Khetha i-Liner Geometry efanele:
  3. Hlola Ukungasebenzi Kahle Kwezinhlelo Zansuku Zonke:
  4. Shintsha Izimpawu Zegolide Njalo:
I-CHANCEPRO ultra-inert GC inlet liner ene-CVD deactivated fused quartz wool kanye ne-capillary guard column

Izixazululo Ze-Chromatography Ze-CHANCEPRO Ultra-Inert

Kuklanyelwe ukuthobela imithetho eqinile yokuphepha kokudla (GB 2763, EU 396/2005, US FDA PAM) nokuthobela imvelo:
  • Izinto Zangaphakathi Ze-GC Ze-CHANCEPRO Ultra-Inert:
  • Amashubhu Okuvikela Angaphambi Kokusebenza (0.25 mm / 0.32 mm / 0.53 mm ID):
  • Ukuhambisana Namathuluzi Wonke:
