Ndeupi musiyano uripo pakati peGC-ms uye GC-MS \ / ms?

Gasi Chromatography-Mass SpectRogry (GC-MS) uye GAC-ms Matipi ese ari maviri anobatanidza chromatographic kupatsanurana nehuremu hwekuona asi dzakasiyana zvakanyanya mukushanda, kunzwa, uye zvinonyatsoitika, uye zvinoshandiswa.

1. Chii chinonzi gc-ms?

GC-ms Gasi Chromatography, iyo inoparadzanisa mishonga yekubatanidza uye yekubatira nepakati uye misa masaga, iyo inozivisa makomputa yakavakirwa pane misa-to-m \ / z \

ZVINOKOSHA ZVINOKOSHA:

• Gasi chromatograph: inoparadzanisa makomponi kuburikidza nekuchengetwa nguva.

• Misa misa spectrometer: ionizere makomputa (kazhinji kuburikidza nemagetsi ionization, EI) uye inogadzira Spectra
  

Kuenzanisira Kuenzanisa:

Inosanganisira Filtration, Solid phase Exction (SPE) kana mvura-yemvura yekubvisa (lle), uye kubva mukugadzira makomichi GC-yakagadzirira.

2. Chii chinonzi gc-ms \ / ms?

GC-ms \ / ms inosvitsa chikamu chechipiri chekuongorora misa. Mushure mekusarudzwa kwekutanga ion mune yekutanga Quadrupole (Q1), yakasarudzwa ions ichisangana-inokonzerwa neyakagadziriswa (cid) muchitokisi chekubatanidza. Fragment ions dzinozoongororwa neyechipiri quadrupole (Q2). Mamwe masisitimu anogona kusanganisira yechitatu quadrupole kana tof auyelyzer

Kuwedzera Kuita:

• Yakakwirira kwazvo uye kunzwa, kunyanya kuburikidza neakawanda maitiro ekugadzirisa (mm)

• Inobudirira mumatanho akaoma, kupa chirevo chaicho uko imwe-stage gc-ms inogona kurwisa
  
  

3. Zvikumbiro

GC-MS:

Inowanzoshandiswa:

• Maitiro enhau ekuongorora

• Forensic kuongorora

• Hunhu hwekudya uye chokwadi

• Environmental inosvibisa kuongorora

GC-MS \ / ms:

Yakanakira:

• Trace quancation (i.e., pesticides at ppt mazinga)

• Akaomarara matrices uko co-elution inoitika.

• Yakakwira-incutput pesticide inoongorora uchishandisa mmm.

• Zvikumbiro zvepamberi, zvakadai sekudya kwekudya uye zvakatipoteredza trace.

5. FAQ

Q1: Ndeupi musiyano mukuru uripo pakati peGC-MS uye GC-MS \ / ms?
A1: GC-MS \ / inopa inovharirwa pachena uye yekunzwa kuburikidza nekuwedzera misa kusefa uye kupatsanurana matanho, yakanaka kune yakaoma samples uye tsananguro yakaoma

Q2: Rini GC-MS YAKADZIDZWA?
A2: Zvekuongorora maitiro ezvinyorwa zvekusimbisa organic kana kunzwa kwekunzwa kuri mwero uye matrices ari nyore.

Q3: Ndirini pandinofanira kushandisa GC-MS \ / ms?
A3: Kune Ultra-trace huwandu mumasampu akaomarara, kutarisisa kwekutarisa, kukwirira-nekucherechedzwa kwekucherechedzwa, uye kufungidzira.

Q4: Inogona GC-MS bata isina-isina kujairika makomputa?
A4: Kwete zvakananga; derivatization inodiwa. Kune yakakura kana inokara mishonga yerevhizimusi, LC-ms kana LC-ms 4./ MS inogona kunge yakakodzera.

Q5: Mari inobhadharwa sei?
A5: GC-ms zviridzwa kazhinji kazhinji zvinodhura (makumi ezviuru eSD). GC-MS \ / ms System (neQQQ kana ION TAP Dhizaini) Inodhura zvakanyanya asi inopa mashura ekuita seyakanyanya kuongorora

GC-ms uye GC-MS \ / ms zvese zvinopa robustical kugona. GC-MS \ / ms inoenderera mberi inosimbisa kunzwa, kusarudza, uye kugadzirwa injere-kunyanya inobatsira mukutsvaga-mwero, yakakwirira-yakaoma kuongorora. Kusarudzwa kunofanirwa kuve kwakavakirwa pazvinhu zvakadai sekutariswa kwekuongorora, sampuke kuoma, kuona miganhu, kuishandisa zvinodiwa, uye bhajeti.
