Ma chromatography-Mass Spectry (GC-MS) ndi njira yamphamvu yowunikira yomwe imagwiritsidwa ntchito kwambiri pakununkhira komanso malonda onunkhira. Njira imaphatikiza kuthekera kwakuthupi kwa chromatography yomwe imawunika ya ma cerotography omwe akuwunika kwa misa misa, ndikupangitsa kukhala chida chofunikira kwambiri kuti chizindikiritse ndi kuchuluka kosakaniza kolakwika kwa mankhwala osasunthika. Nkhaniyi iyang'ana kwambiri chifukwa chake GC-MS imakometsedwa ndi kununkhira kwa kununkhira, kuwunika kwa kununkhira, mfundo zake zogwiritsira ntchito, zabwino zake, ndi ntchito.
Kodi GC-MS ndi chiyani?
Gasi chromatography (GC) ndi njira yomwe imalekanitsa mankhwala osasunthika mu osakaniza motengera kusinthika kwawo ndi kulinganiza kwawo ndi gawo lawo. Chitsanzo chimasokonekera ndi mpweya wa bart (nthawi zambiri hermorgen kapena hydrogen) ndikudutsa mzere wa chromatographic pomwe zigawo zimalekanitsidwa ndi mfundo zawo zowotcha.
Misa Spectring (MS) ndi njira yowunikira yotsatira gc pomwe mafuta olekanitsidwa ndi aionized ndi kuchuluka kwawo kwapadera kumayesedwa. Njirayi imapereka chidziwitso mwatsatanetsatane zolemera komanso kapangidwe ka chinthu chilichonse, kulola chizindikiritso chodziwika bwino.
Mukufuna kudziwa zambiri za kusiyana pakati pa LC-MS ndi GC-MS, chonde onani nkhaniyi: Kodi pali kusiyana kotani pakati pa LC-MS ndi GC-MS?
Momwe GC-MS imagwira ntchito
Kuyamba: Chitsanzo, nthawi zambiri chimakhala mu mawonekedwe amadzimadzi, chimalowetsedwa mu GC System.
Vaporrization: Sampuya imatenthedwa, ndikupangitsa kuti isungunuke.
Kupatukana: Sampuya yoyamwa imadutsa mzere wa chromatographic, pomwe zigawo zina zimalekanitsidwa kutengera katundu wawo.
Ionani: Pamene mankhwalawa amasiya mzatiyo, amalowa mtunda wa misa, komwe amakonzera.
Kusanthula Kwambiri: ma ion amalekanitsidwa chifukwa cha kuchuluka kwawo kwapadera, kupanga misa yambiri yomwe imayimira zigawo za chitsanzo choyambirira.
N 'chifukwa Chiyani Muyenera Kugwiritsa Ntchito DC-MS Zokopera ndi Kusanthula Koma?
1. Kusanthula kwa zosakaniza zovuta
Zonunkhira zambiri komanso zonunkhira nthawi zambiri zimapangidwa ndi zosakaniza zovuta zomwe zimakhala ndi mazana zikwizikwi. GC-Ms wopambana kwambiri kulekanitsa zinthu izi, kulola kuti muchepetse kuwunika kwapadera kulikonse komwe kumakhalapo. Kulemphana kumeneku ndikofunikira kuwongolera kwapadera komanso chitukuko chazogulitsa mu chakudya ndi chakumwa.
2. Malingaliro ndi mawonekedwe
GC-MS imadziwika chifukwa cha chidwi chake chachikulu, chomwe chimapangitsa kuti chizindikiritse mankhwala otsika kwambiri (magawo pa biliyoni). Kukhutira kumeneku ndikofunikira makamaka pakukopera komanso kusanthula kununkhira, ngakhale kuti kumangochulukitsa kumatha kumakhudza kwambiri fungo komanso kukoma. Kuphatikiza apo, mawonekedwe a misa misa amalola kuzindikiritsa kolondola motsutsana ndi zovuta.
3. Kusanthula Kwambiri
GC-MS imapereka chidziwitso chonse komanso chizindikiritso choyenerera. Poyerekeza malowo pansi pa chiwalo cha chromatogramu kudera lomwe lili pansi pa chiwonetsero chovomerezeka, akatswiri amatha kudziwa kuchuluka kwa kusakaniza kwinakwake. Kuchuluka kwa kuchuluka kwake ndikofunikira potsatira malamulo ndikuwonetsetsa kuti zinthu sizisintha.
4. Kusiyanitsa pamapulogalamu
Kugwiritsa ntchito mankhwala a GC-MS kumathandizira kuti igwiritsidwe ntchito m'malo osiyanasiyana a kukoma ndi kusanthula kwa
Makampani Ogulitsa Mankhwala: Ankakonda kusanthula zinthu zosasunthika mu chakudya ndi zakumwa zowonetsetsa kuti zitsimikizike.
Zodzikongoletsera: Onaninso kununkhira kosasinthika kuti musinthe komanso mtundu kuchokera ku batch kuti mutenge.
Kuwunika kwa chilengedwe: kuzindikira zosintha zachilengedwe (vocs) mumlengalenga kapena zitsanzo zamadzi, zomwe zimatha kukhudza malembawo popanga chakudya.
5. Kukula Kwatsopano Kwatsopano
GC-MS imagwira ntchito yofunika kwambiri pakukula, kuthandiza ofufuza kuti adziwe kukoma kwatsopano kapena kukonza mawonekedwe omwe alipo. Mwa kusanthula mitundu yosiyanasiyana ya zosakaniza, opanga mapulogalamu amatha kupanga zokongoletsera zapadera zomwe zimakwaniritsa zokonda zofuna kugula pomwe zikukwaniritsidwa.
Zabwino zogwiritsa ntchito GC-MS
1. Borustness
Makina a GC-MS ali okhazikika kwambiri ndipo amatha kuthana ndi mitundu yosiyanasiyana yopanda zovuta kwambiri kapena kukonza. Kudalirika kumeneku ndikofunikira kwa ma laborator omwe amagwiritsa ntchito kusanthula kwakukulu.
2. Nthawi Yachangu
GC-MS ili ndi nthawi yochepa yopenda mwachidule poyerekeza ndi njira zina, kulola malobori kuti athe kukonza zitsanzo zingapo moyenera. M'malo ogulitsa, nthawi yotembenuka mwachangu ndi yovuta chifukwa nthawi yamasika imakhudza mpikisano.
3. Mbadwo wathunthu
Kuphatikiza kwa chromatographic kokhazikika komanso mibadwo yazidziwitso ya misa imapereka chidziwitso chokwanira pazinthu ndi kuchuluka kwa chinthu chilichonse chophatikizika. Chidziwitso chotopetsa ichi chimathandiza kumvetsetsa bwino zopanga.
4. Ntchito yofananira
Misa Spectry ikhoza kukhala laibulale yofanana ndi zosunga zambiri zomwe zili ndi spectra ya mankhwala odziwika. Ntchitoyi imasinthitsa njira yodziwitsa mwa kupereka tanthauzo lofananizira.
Kugwiritsa ntchito GC-Ms Panu ndi Kusanthula Kwawo
1. Kusanthula Kwake
GC-MS imagwiritsidwa ntchito kwambiri posanthula zokongoletsera mu chakudya, kuthandiza opanga kumvetsetsa momwe zosakaniza zimakhudzira kukoma ndi fungo.
2.
Mu chakudya ndi zodzikongoletsera zodzikongoletsera, GC-MS ndi chida chofunikira chowongolera kuti zitsimikizire kuti zinthuzo zimakumana ndi mfundo zapadera zokhuza kukoma.
3.
Mayiko ambiri amateteza ndalama zotetezeka komanso zonena za kulembera miyezo. GC-MS imatha kuthandizira kuonetsetsa kuti mukutsatira molondola mwa zinthu zomwe zingakhalepo kwa zinthu zomwe zingawonongeke kapena ziweto.
4. Kufufuza ndi Kukula
Ofufuzawo amagwiritsa ntchito GC-MS kuti asanthule mitundu yatsopano kapena yophunzira momwe njira yoyendetsera njira zomwe zimakhudzira ma procts osasunthika kuti mukwaniritse zatsopano.
Gasi Chromatography-Mass Spectry (GC-MS) ndiukadaulo wofunikira pakununkhira komanso kusanthula kununkhira chifukwa kumatha kusiyanitsa zozimitsa zovuta pomwe amapereka chidziwitso chokwanira pazinthu zomwe zili patsamba. Kulimba kwake, kusanthula kwake mwachangu, kuthekera kosiyanasiyana pamapulogalamuwo kumapangitsa chida chofunikira kwambiri kwa mafakitale monga kupanga zakudya komanso zodzoladzola.
Monga momwe othandizira amakondera ndikupitilizabe kusintha, udindo wa GC-m mas polimbikitsa kuti muwonetsetse kuti mitundu ya chitetezo komanso yokhazikika imakwaniritsidwa pamakampani azikhala ofunika kwambiri. Mwa kukonza ukadaulo wowunikirawu, makampani amatha kukulitsa zopereka zawo zogulitsa pogwiritsa ntchito zofunika kwambiri.
Achizungu
