Menene banbanci tsakanin GC-MS da GC-Ms \ / ms?

Gas Chromatography-Mass Spectometry (GC-Ms) da gas Chromatography-Tandem Mass Spectretry (GC-Ms \ / MS) kyawawan dabaru da aka yi amfani da su a cikin fannoni kamar su, kimiyyar abinci, amincin abinci, da amincin abinci, da aminci. Dukkanin fasahohin biyu sun hada Chromatographic rabuwa tare da taro na spectrometric amma bambanta bambance bambancen aiki amma ban sha'awa, da dama, da aikace-aikace.

1. Menene GC-ms?

GC-MS Ma'auratan Gas na Chromatography, wanda ke raba mahadi maras tsayi ta hanyar tafiye-tafiye tare da tsarin masarauta, wanda ke bayyana mahadi sakamakon cajin (m \ / z) rabo

Abubuwan da key:

• Gas Chomatograph: Musanya mahadi ta hanyar riƙewa lokaci.

• Taro spectrometer: oonizes mahadi (yawanci ta hanyar lantarki ionization, ei) kuma ya samar da Spectra
  

Samfura Samfura:

Ya hada da tanki, ingantaccen lokaci (hakar lokaci) ko hakar ruwa-ruwa (lle), da kuma derivatization don yin mahadi GC-shirye.

2. Menene GC-ms \ / ms?

GC-MS \ / MS ta gabatar da mataki na biyu na bincike na biyu. Bayan zaɓi na farko a farkon quadruple (Q1), zaɓaɓɓen ions ya saba da rikice-rikice na rikice-rikice (CID) ta hanyar tantanin cuta. Ana bincika ƙwararrun ƙwararraki ta sauƙaƙe na biyu (Q2). Wasu tsarin na iya hadawa da quadrupole na uku ko kuma nazarin Tof

Ingantaccen aiki:

• Mafi girman bayani da hankali, musamman ta hanyar dauki matakan dauki dauki da yawa (Mrm)

• Inganci a cikin hadaddun matrices, samar da takamaiman ganewa inda gc-ms-ms na iya gwagwarmaya
  
  

3. Aikace-aikace

GC-MS:

Amfani da shi don:

• Binciken VoC na yau da kullun

• Binciken Binciko

• Ingancin abinci da amincin

• Zane mai cike da muhalli

GC-ms \ / ms:

Daidai ne:

• Damacciyar darajar (misali, magungunan kashe qwari)

• HUKUNCIN Matrijiyoyin da ke da ƙima na faruwa.

• High-isasshen PRICEDING ta amfani da MRM.

• Aikace-aikacen ci gaba, kamar su kayan abinci da wuraren gano kayan abinci.

Q1: Wane bambance-bambance-bambance ne tsakanin GC-Ms da GC-Ms \ / ms?
A1: GC-MS \ / MS \ / MS \ / MS \ / INFEITY ta hanyar ƙarin ƙarin adadin taro da kuma matakan rarrabuwa da ganowa

Q2: Yaushe GC-Ms ya fi so?
A2: Don bincike na yau da kullun game da m mahaɗan ƙwayoyin cuta lokacin da ake buƙata na buƙatun matsakaici da matrixes masu sauki ne.

Q3: Yaushe yakamata in yi amfani da GC-ms \ / ms?
A3: Don Ulancin-Trace-Trace-trage a cikin samfuran hadaddun muhalli, saka idanu na muhalli, alamomi masu kyau, da kuma tantance mahimmin iko.

Q4: Can GC-ms rike da abubuwan da ba a cikin ba?
A4: Ba kai tsaye; ana buƙatar derivatization. Don mafi girma ko ƙwayoyin jileji, LC-MS ko LC-MS \ / MS na iya zama mafi dacewa.

Q5: Ta yaya kudin farashi?
A5: Kayan aikin GC-Ms ba su da tsada (dubun dubatar da USD). GC-ms \ / MS Tsarin (tare da QQS Trap

GC-MS da GC-Ms \ / Ms Dukansu suna ba da damar tsawanta na zamani. GC-ms \ / ms ƙarin haɓakar jin daɗin rayuwa, Zabi, da kuma tsinkayar hankali musamman-musamman da aka gano, nazarin-hadaddun mai rikitarwa. Selection should be based on factors such as target analytes, sample complexity, detection limits, throughput requirements, and budget.
