Indlela Yokukhipha I-Septa Coring, Ukuvaleka Kwenalithi, kanye Ne-Ghost Peaks Ku-GC-MS & HPLC Sequences

Kuma-GC-MS nama-HPLC anomthamo ophezulu, ama-ghost peaks nokuguquguquka kwe-baseline kuvame ukuvela enkingeni eyodwa yemishini: ukugwaza kwe-septum. Lapho izinalithi ze-autosampler zigwaza ngokuphindaphindiwe ama-septa angalungiselelwe kahle, izingcezu ezincane ziyahlukanisa zingene esitsheni sesampula noma ekuvuleni, okubangela ukuvaleka, ukungcola, nama-ghost peaks e-siloxane (207, 281, 355).
Inalithi ye-GC-MS autosampler igwaza i-septum yebhodlela ibangele ama-ghost peaks e-siloxane

Okubalulekile Okutholakele

  • Indlela Eyinhloko:
  • Isignesha ye-Mass Spec:
  • Ukulungiswa Kobunjiniyela: ama-septa e-PTFE/Silicone ahlanzekile kakhulu, ahlanganiswe ngokushisa, a-slit ngaphambilini

Yini Ebangela Ukugwaza Kwe-Septum Nokungcola Kohlelo?

Ukubhoboza Okuphindwayo ➔ Ukusikwa Komshini (I-Coring) ➔ Izinhlayiyana Esampulini/Emnyango ➔ Amaphuzu Aphezulu E-Siloxane + Ukuvaleka Kwenalithi
Inalithi yokugawula i-septa emsindweni we-GC-MS icwecwa izingcezu ze-silicone
  1. Amandla Okusikwa Komshini:
  2. Ukungena Kokushisa Emnyango:
  3. I-HPLC Check Valve Nokungcola Kwekholomu:

Ama-Septa Ajwayelekile vs. Ama-Septa Ahlanzekile Kakhulu Asikiwe Ngaphambilini

Ipharamitha
Ama-Septa Ajwayelekile e-9-425 PTFE/Silicone
Ama-Septa Ahlanzekile Kakhulu Asikiwe Ngaphambilini e-CHANCEPRO 9-425
Ukumelana Nokugwaza
Phezulu (ingozi yokugoba/ukugwaza inalithi)
Phansi (umhlahlandlela onembile we-slit eyodwa/ephambanayo)
Izinga Lokugwaza (Imijovo Engaphezu Kwe-50)
Ukukhiqizwa kwezingcezu ezingu-12%–25%
0% (Isiqinisekiso Sokungabikho Kwe-Coring)
Isizinda Se-Siloxane (
207, 281)
Phakathi nendawo kuya phezulu (ukuncibilika kwe-adhesive/raw silicone)
Phansi kakhulu (ukubopha ngokushisa ngaphandle kwe-solvent + ukukhishwa kwe-vacuum)
Ukuvimbela i-Vacuum Yebhodlela
Ivamise ukuvaleka nge-vacuum lapho kudonswa umthamo omkhulu
I-slits isebenza njengendlela yokukhulula ingcindezi ngaphandle kokulahlekelwa yi-solvent
Izinhlelo Zokusebenza Eziqondiwe
I-QA/QC ejwayelekile yomjovo owodwa
I-GC-MS, LC-MS, CRO enomthamo ophezulu
Ukuqhathanisa i-septum ye-PTFE silicone ejwayelekile engu-9-425 ne-septum ye-chromatography ehlanzekile ecwengekileyo

Izinqubo Ezing краше Kakhulu Zokuvimbela Ukugqekezwa Nomsindo Wangemuva

  1. Qondanisa Usayizi Wenalithi Nesitayela Sethiphu:
  2. Shintshela Kuma-Design Asikiwe Ngaphambilini Ukuze Ujove Kaningi:
  3. Qinisekisa I-Bonding Chemistry: ukuhlanganiswa ngokushisa ngaphandle kwe-glue
  4. Implement Inlet Maintenance Intervals:

CHANCEPRO Ultra-Clean 9-425 Chromatography Solutions

Klelwe ukuhlaziywa okunzima kokulandelela, imisebenzi ye-CRO, nokuhlolwa kwemithi okulawulwayo:
  • Izivalo Zokunemba Ezi-Slit Ngaphambilini:
  • Ukuhlanganiswa Okushisayo Okungenayo i-Solvent:
  • Ukupakisha Okuhlanzekile Okungenamoya Ngokukhipha Umoya:
