Nguwuphi umahluko phakathi kwe-GC-NS kunye ne-GC-Nks \ / Nks?

I-chromatography-mass spectrometry (GC-MS) kunye ne-chromatography-tandem ye-chactrametry (GC-\ /s) ziindlela ezinamandla zokuhlalutya ezisetyenziswayo kwimihlaba efana ne-chiemuceuticals, iSayensi yokutya, kunye neFournsics. Zombini ubuchwephesha badibanisa ukwahlulwa kwe-chromatographic kunye ne-spectrometric efunyenweyo kodwa yahlukile ekusebenzeni, ubuntununtunu, ubuntu, kunye nokusetyenziswa.

1. Yintoni i-GC-Nks?

I-GC-NS itshatise i-chromatography yegesi, eyahlulahlula amakhonkco okubiwa ngamanqaku abilayo kunye nokusebenzisana nenqanaba lesitayile, echaza imilinganiselo esekwe kwi-Mass

Izinto eziphambili:

• I-chromatograph yerhasi: Yahlulahlulahlulwa kweendawo zokugcina ixesha.

• I-Mass Spectrometer: I-Iosted I-Computers (iqhelekile kwi-Ionron ye-Eletron, i-EI) kwaye ivelisa uphawu
  

Ukulungiselela isampulu:

Kubandakanya ukuqulunqwa, ukususwa kwesigaba sokuqina

2. Yintoni i-GC-ms \ / Nks?

I-GC-Nks \ / Nks indanisa inqanaba lesibini lohlalutyo lwesininzi. Emva kokukhetha i-ion yokuqala ye-quadrupole (Q1), ii-ions ezikhethiweyo zenziwe nge-collices I-ion ye-ions ziyahlalutywa yi-quadrupole yesibini (Q2). Ezinye iinkqubo zinokubandakanya i-quadrupole yesithathu okanye i-tof realleler

Umsebenzi ophuculweyo:

• Ubunyani obuphezulu kunye nemvakalelo, ngakumbi ngokujonga okuninzi kweliso (i-MRM)

• Isebenza kakuhle kwiimatriki ezintsonkothileyo, ukubonelela ngesaziso esichanekileyo apho i-GC-Nks inokuzabalaza
  
  

3. Izicelo

I-GC-Nks:

Isetyenziselwa ukusetyenziswa:

• Uhlalutyo lweVOC

• UPRANIST

• Umgangatho wokutya kunye nobunyani

• Uvavanyo olungcolisekileyo lokusingqongileyo

I-GC-Nks \ /Ms:

Ilungele:

• Ukulandelela

• Imatriki enzima apho kwenzeka khona.

• Ukutyikitywa kwe-Desticide yePiestide usebenzisa i-mrm.

• Izicelo eziPhambili, ezinjengeemorinsi zokutya kunye nokufunyanwa kwendawo yokusingqongileyo.

I-5. FAQ

I-Q1: Nguwuphi umahluko omkhulu ophakathi kwe-GC-NS kunye ne-GC-Nks \ / Nks?
I-A1: GC-Nks \ / Ms ibonelela ngokuphuculwa okuphuculweyo kunye nemvakalelo yokuphucula amanqanaba ongezelelweyo okucoca kunye namanqanaba okuqhekeka, kufanelekile ukuba iisampulu ezintsonkothileyo kunye nokufumana umkhondo

I-Q2: I-GC-DS ikhethwa nini?
A2: Uhlalutyo lwesiqhelo lweendawo ezingcolisekileyo eziguqukayo xa iimfuno zemvakalelo zilula kwaye imatriki zilula.

Q3: Ndingayisebenzisa nini i-GC-Nks \ / Nks?
A3: Ukulungiselela ukulandelwa kwe-Ultra kwiisampulu ezintsonkothileyo, ukuhlolwa kwendalo esingqongileyo, ukuhlolwa kwegalelo eliphezulu, kunye nokuchongwa kwengxelo ye-forensic.

I-Q4: Ngaba i-GC-MS ibamba i-non-cotiles?
A4: hayi ngqo; I-Derivatating iyafuneka. Kwimigangatho emikhulu okanye ye-LC-Nks okanye i-LC-Nks \ / IMS inokuba ilungile ngakumbi.

Q5: Zithelekiswa njani neendleko?
I-A5 yezixhobo ze-GC-MS zihlala zibiza kakhulu (amashumi amawaka e-USD). I-GC-Nks \ / sks System (kunye ne-QQQ okanye i-Ion TrapUtions) ixabisa kakhulu ngaphandle kokusebenza okuphezulu kuhlalutyo oluphakamileyo

I-GC-Nks kunye ne-GC-Nks \ / Ms zombini zinikezela amandla ohlalutyo. I-GC-Nks \ / Ms ngakumbi ukuphucula imvakalelo, ukukhetha, kunye nokuqonda ngokwalesakhiwo- iluncedo kakhulu kwinqanaba lomkhondo, ukuhlalutya okukhulu. Ukukhetha kufuneka kusekwe kwizinto ezinje ngeethagethi, iithamsanqa, imida yokufumanisa, iimfuno zokufaka, kunye nohlahlo-lwabiwo mali.
