Indlela Yokuqeda Ukukhishwa Kwezihlungi Zemijovo kanye nama-Ghost Ions Ekuhlaziyweni Kwe-LC-MS/MS Okulandelekayo

Ku-metabolomics engaqondiwe, ukuhlolwa kwe-high-resolution mass spectrometry (HRMS), kanye nokuhlolwa kwe-Pharmaceutical Extractables & Leachables (E&L), ukuhlanzwa kwesampula nge-syringe filters ezijwayelekile kuvame ukuletha ukungcola okunzima kwe-chemical background. Abahlaziyi abasebenzisa i-Nylon ejwayelekile noma ejwayelekile kanye ne-PTFE filters ezijwayelekile bavame ukubona amaqoqo anamandla e-oligomer angaziwa, ama-plasticizer, nama-surfactant avala ama-target analytes anesisindo esincane futhi onakalisa ukufanisa kwelabhulali ye-spectral.
Ukungcola okukhiphekayo kwe-syringe filter ekulungiseleleni ukuhlunga amasampula e-LC-MS elabhorethri

Okubalulekile Okutholakele

  • Inkinga Nge-Filters Ezijwayelekile:
  • Ukuphazamiseka Kwe-MS Okujwayelekile:
  • Ukulungiswa Kobunjiniyela: Ama-membrane e-LC-MS grade aqinisekisiwe, angena-glue, ahlanganiswe nge-ultrasonic welding, ama-PTFE hydrophilic akhishwe ngaphambilini noma ama-PES protein-low

Indlela Yokukhishwa Kwe-Extractables kanye Nomthelela Ku-MS

Isigaba / Isinyathelo
Indlela Yemichiza Nengokomzimba
Umphumela Wokuhlaziya Ku-LC-MS/MS
1. Ukuthintana Ne-Solvent
Ama-solvent aqinile aphilayo (MeOH, ACN) amanisa ulwelwesi kanye ne-housing ye-polypropylene
Ama-solvent akhulisa i-polymer matrix futhi ancibilikise izithasiselo ezingaphendulwanga
2. Ukuncibilika Kokungcola
Ama-slip agents (oleamide/erucamide), ama-curing agents, kanye nama-adhesives ancibilika kwi-filtrate
Ukuncibilika kwezinto ezinamandla aphansi ezingaboshelwe ngamakhemikhali
3. Ukuncintisana kwe-Ionization
Ama-surfactant ne-oligomer ezacile khipha ngaphesheya kwe-chromatographic gradient
Ukucindezelwa okunzima kwe-ESI ionization kwama-metabolite endabuko anamanani aphansi
4. Ama-Spectral Artifacts
I-polymeric repeating ion series igcwalisa i-MS1 ne-MS2 spectra
False-positive matches in HRMS databases (e.g., METLIN, NIST)
I-chromatogram ye-mass spectrometry eqhathanisa iziqongo zama-ion ezingabonakali ezikhiphekayo nge-filter ne-baseline ehlanzekile

Common Extractable Profiles by Membrane Chemistry

Izinto ezihlukene zokwakha ulwelwesi nezinqubo zokukhiqiza zikhipha izinhlobo ezithile zamakhemikhali eziphazamisa ububanzi obuhlukene bezisindo:
  • I-Polyamide / i-Nylon ejwayelekile:
  • I-PTFE enezindleko eziphansi eboshelwe nge-glue:
  • Izithasiselo ze-Polypropylene Housing:

Izinqubo ezinhle zokunciphisa izinto ezikhiphekayo ngesikhathi sokuhlunga amasampula nge-syringe filter ku-LC-MS

Izinqubo Ezi-4 Ezingcono Kakhulu Zokunciphisa Okukhishwayo Ngesikhathi Sokuhlunga Isampula

  1. Lahla I-Filtrate Yokuqala (Pre-Flush):0.5 mL kuya ku-1.0 mL
  2. Qeda i-Nylon ye-Mass Spectrometry: i-Hydrophilic PTFE engenamsebenzi ngamakhemikhali noma i-Polyethersulfone (PES) enganamatheli kancane
  3. Qinisekisa Ukwakhiwa Okungenayo i-Adhesive:
  4. Sebenzisa Ama-Syringe Filter Blanks:

Ama-Syringe Filters e-CHANCEPRO Certified Ultra-Clean LC-MS

Akhelwe ngokukhethekile i-non-targeted metabolomics, i-forensic screening, kanye nokuhlaziya amazinga aphansi e-trace-level impurities:
  • Ama-Membrane Asebenza Ngaphambilini Ahlanzekile Kakhulu:
  • I-Virgin Housing Engenazo I-Additive:
  • Isitifiketi Se-Batch-Specific LC-MS/MS:
