Kushandiswa kweGC-MS mune yekuchengetedza kuchengetedza bvunzo

Gasi Chromatography-Mass SpectRometry (GC-ms) ndeye Ine Inosimba Yekuongorora maitiro ayo anoshandiswa zvakanyanya mukuedzwa kwekuchengetedza chikafu. Iyo nzira inosanganisa mukurumbira wekuparadzaniswa kwegasi neChromatography nekugona kwehuwandu hwekuongorora misa kweMisangano Yekusimbisa Kunogonesa kuongororwa kwezvinhu zvakaoma zvematrices. Izvi zvinotevera kutarisisa kwekukosha, zvinoshandiswa, uye zvakanakira zveGC-MS mukuona kuchengetedzwa kwekudya.

GC-ms yakakosha yekuzivisa uye inokatyamadza inosvibisa uye inosara muchikafu. Kunzwa kwayo kukuru uye kusarudzika kunoita kuti zvive zvakanyatsonaka kuongorora zvakaderera-polarity, kuisana, uye kugadzikana kwakasimba, kunozivikanwa munzvimbo dzekuchengetedza chikafu. Maitiro akakosha ekuona zvinhu zvinokuvadza zvakadai semishonga yekuuraya zvipembenene, masimbi anorema, uye zvimwe zvinosvibisa izvo zvinogona kuisa njodzi kune hutano hwekutengesa hutano.

Kuti uwane rumwe ruzivo nezve autosamupler vials yegesi chromatography, kureva chinyorwa ichi: 2ml autosamppler vials yegesi chromatography

Kushandiswa kweGC-MS mukuchengetedza chikafu

1. Kuuraya Pestic Long Ongororo: Imwe yeiyo mainal application yeGC-ms mukuchengetedzeka kwechikafu ndeyekuonekwa kwehenderekedzo ye porticide. Nezvekuwedzera zvinetso nezvezvikonzero zvechipfuva zvehutano hwevanhu uye zvakatipoteredza, masangano ekudzora anoda kuyedzwa kuyera kuti ave nechokwadi chekuti chikafu chinosangana nekuchengetedza tsika dzekuchengetedza. GC-ms inokwanisa kuona mishonga yakawanda yakasara panguva imwe chete, ichiita sarudzo inoshanda yemabharabhu ekuita kuti anyatsoongorora.

2.. Maitiro acho anokwanisa kupatsanura mishonga yakaoma, saka trace huwandu hwezvakashata izvo zvingaitika zvisingaonekwe zvinogona kucherechedzwa. Kugona uku kwakakosha kuti uve nechokwadi chekuti zvigadzirwa zvekudya zvakasununguka pazvinhu zvinokuvadza uye kuchengetedza hutano hweveruzhinji.

3. Nekuongorora mishonga inosimbisa inokonzeresa kuravira uye kunhuhwirira, vagadziri vanogona kuvandudza chigadzirwa mhando uye kutevedzana kwemutengi. Ichi chishandiso chinoratidza kuwanda kweGC-ms, iyo isingagumi kune nyaya dzekuchengetedza.

4. Kuongororwa kwehutano: GC-ms inogona kushandiswa kuongorora zvirimo zvekudya zvekudya, senge mafuta eacids uye mavitamini. Ichi chishandiso chinonyanya kukosha pakuratidzira maResufacturers 'hutano hwehutano. Kunyorwa kwakatyisa kwehutano kunobatsira vatengi kuita sarudzo dzekudya.

5. Hunhu hwekudzora: Kuwedzera pakuona zvinosvibisa, GC-MS inotamba chinzvimbo chakakosha mukugadzirisa kwemhando yekugadzirisa muindasitiri yechikafu. Nekuona kusanzwisisika mune flavor profiles uye kuumbwa kwehunyanzvi, vagadziri vanogona kuchengetedza zvakakwirira zviyero zvezvigadzirwa zvavo.

Zvakanakira kushandisa GC-MS yekuyedzwa kwekudya

Kukwikwidza kwepamusoro uye kusarudza: GC-ms inogona kuona makomputa zvakanyanya nekukasira (zvikamu pamabhiriyoni), zvichiita kuti ive yakakodzera kuongorora zvinoshatisa zvinosvibisa.

Kuongorora kwakazara: Iko kusanganiswa kwegesi chromatography uye misa misa misa inogona kuita kuongororwa kwakakodzera uye kuwanda kwemasampu akaomarara.

Kuedza: GC-MS inogona kuongorora akasiyana emakompeni mumhando dzakasiyana-siyana dzematrices dzekudya, kusanganisira solids, zvinwiwa, uye magasi.

Migumisiro inokurumidza: Iyo tekinoroji inopa zviwanikwa zvekuongorora nekukurumidza, izvo zvakakosha kuti urambe uchichengetedza zviyero zvekuchengetedza chikafu mune indasitiri inokurumidza.

Unoda kuziva zvakawanda nezve mutsauko pakati peLC-ms uye GC-MS, ndapota tarisa chinyorwa ichi:Ndeupi musiyano uripo pakati peLC-ms uye GC-MS?

Kuchenjera kweGC-MS mukuedzwa kwekudya

Kuti uwedzere kunatsiridza zvakanyatsojeka kweGC-MS kusawanikwa kwezvekudya zvekudya, kuongororwa kunoitwa zvinoenderana nemamiriro ekushandisa chaicho.

Chekutanga, nyatsonzwisisa zvizere hunhu hwemasampula ekudya kuti uongororwe, uye zvesayenzi uye zvine rutsics sarudza nzira yeGC-ms. Panguva imwecheteyo, gadzira chiitiko chakakwana chekuongororwa uye maitiro ekugadzira, uye ita kuti gadziriswe gadziriro yekugadzirira neimwe nzira yekunyorera yegirasi. Zvinoshanda zvinobudirira uye kuderedza zvinhu zvakasiyana siyana zvisina kujairika muchikamu chekuedza kudzivirira maitiro pakukonzerwa nekuwanikwa kwemhedzisiro uye kuve nechokwadi chekushandiswa kweGC-ms application kune zvinowanikwa zvinovandudzwa.

Chechipiri, nyatso shandisa paramita yegesi chromatography-misa misa mishonga midziyo. Semuenzaniso: Kuisa tembiricha yekoramu bhokisi, kusarudzwa kweiyo detector, kusarudzwa kweiyo Chromatographic column, etc. inofanirwa kuzadzisa zvinodiwa pakuedzwa. Gadzirisa nharaunda yakazara yekuongorora kwechikafu kuti ive nechokwadi chekushanda uye njere kusarudzwa kwechiridzwa. Asati aedza vashandi vanoshandisa zviri pamutemo iyo GC-ms chiridzwa, ivo vanofanirwa kutarisa chokwadi chemidziyo zvakare. Enzanisa kuyedza bvunzo uye wozviongorora kuti vave nechokwadi chekuti kuongororwa kwekudya kunosangana nezvinodiwa zvechromatography-misa spectrometry tekinoroji.

GC-ms azova tekinoroji yekuchengetedza kwekuchengetedza kwekudya nekuona kwayo kwekushungurudzika kwayo, kuisazve, uye kugona kuitisa kuongororwa kwakazara kwezvinhu zvakasiyana siyana. Nekukura kuri kuramba kuchisimba Nekutora izvi tekinoroji yeudiki
