Kodi pali kusiyana kotani pakati pa gc-ms ndi gc-ms \ / ms?

Ma chromatography - misa spectmetry (GC-MS) ndi mpweya chrometography-tandem spectometry (GC-MS) ndi njira zachilengedwe zogwirira ntchito, sayansi yachilengedwe, chitetezo cha chakudya. Njira zonse ziwiri kuphatikiza ma chromatographraphic kuphatikizika kwa misa koma kumasiyana kwenikweni pakugwira ntchito, chidwi, mwachindunji, ndi ntchito.

1. Kodi GC-MS ndi chiyani?

GC-MS okwatirana a chromatography, yomwe imalekanitsa zinthu zosasunthika ndi gawo lowotcha ndi njira yolumikizirana ndi gawo lalikulu, lomwe limazindikiritsa mankhwala okhazikika (m \ z).

Zigawo zazikuluzikulu:

• Chromatograph: imalekanitsa mankhwala kudzera nthawi yosunga.

• Misa spectrometer: ma ionizes mankhwala (wamba kudzera pa electron, ei) ndikupanga spectra
  

Kukonzekera zitsanzo:

Kuphatikiza kusefa, gawo lolimba (SPE) kapena madzi-madzi kusefukira (LLE), ndi derivatation kuti apange mankhwala okonzeka.

2. GC-MS \ / ms?

GC-MS \ / MS imabweretsa gawo lachiwiri la kusanthula kwakukulu. Pambuyo pokonzanso ma ion osankhidwa mu quadruple yoyamba (Q1), ma ions osankhidwa omwe amabwera chifukwa cha cell (ced) mu cell. Chidutswa chabodza chimasanthula ndi quadrupse yachiwiri (Q2). Makina ena angaphatikizepo mtundu wachitatu kapena tfa

Magwiridwe Ake:

• Zachilengedwe komanso chidwi, makamaka kudzera pazinthu zingapo zowunikira (arrm)

• Kugwiritsa ntchito matrict ovutikira, kupereka chizindikiritso chotsimikizika komwe GC-MS imatha kulimbana
  
  

3. Ntchito

GC-MS:

Zomwe zimagwiritsidwa ntchito kawiri:

• Kusanthula kwa Voutine Voc

• Zofufuza zamtsogolo

• Chakudya chamtundu ndi chotsimikizika

• Kuyang'ana zachilengedwe

Gc-ms \ / ms:

Zabwino kwa:

• Tsatirani Zowonjezera (E.g.

• Matricts osavuta komwe kulumikizana kumachitika.

• Kuyang'ana kwambiri kuzolowera kugwiritsa ntchito marrm.

• Mapulogalamu otsogola, monga chakudya cha chakudya ndi kupezeka kwachilengedwe.
  
  

  

4. Kusiyana kwakukulu

5. FAQ

Q1: Ndi kusiyana kwakukulu kotani komwe kuli pakati pa GC-MS ndi GC-MS \ / ms?
A1: GC-MS \ / MS imathandizira kusanja ndi kukhudzila kudzera muzowonjezera zosewerera ndi kuphatikizika, zabwino pa zitsanzo zovuta ndi kuzindikira

Q2: Kodi GC-MS imakonda liti?
A2: Kusanthula kwa zinthu zosinthika kwa orsolatile omwe amaphatikizidwa pakumva chidwi kwambiri komanso materics ndi osavuta.

Q3: Ndiyenera kugwiritsa ntchito liti GC-MS \ / ms?
A3: Pazinthu za ultra-trace mu zitsanzo zovuta, kuwunika kwachilengedwe, kuwunikira kwambiri, ndi kuzindikiritsa kuwonekera.

Q4: Kodi GC-MS ithetse mankhwala osasunthika?
A4: Osati mwachindunji; Kusiyidwa ndikofunikira. Kwa mankhwala owonjezera kapena amphamvu kwambiri, LC-MS kapena LC-MS \ / MS ikhoza kukhala yoyenera.

Q5: Kodi ndalama zimafanana bwanji?
A5: Zida za GC-MS nthawi zambiri zimakhala zotsika mtengo (makumi zikwizikwi za USD). GC-MS \ / MS Systems (ndi QQQ kapena ion kapena ion Curtuption) Mulingo kwambiri koma perekani magwiridwe antchito apadera

GC-MS ndi GC-MS \ / ma MS onse amapereka mphamvu zolimba. GC-MS \ / MS ikuthandizira pakuyankhulana, kusanza, komanso kumvetsetsa kwazinthu, makamaka pakuwunika, kuchuluka kwambiri kosavuta. Kusankhidwa kuyenera kukhazikitsidwa ndi zinthu monga momwe mukufuna kuwunikira, zitsanzo zovutikira, malire ozindikira, zofunikira zakutha, ndi bajeti.
