Ta yaya HPLC ta bambanta da shafin GC?

HPLC (babban aiki na ruwa na ruwa) da GC na gas (ƙamshin gas) sune ingantattun dabaru masu ƙarfi da aka saba da su don rabawa, gano mahadi, da ƙarin mahadi a cikin samfuran samfura iri-iri. Koyaya, sun banbanta sosai dangane da aikin aiki, kayan aiki, da aikace-aikace. Wannan labarin ya yi amfani da mahimman bambance-bambance tsakanin HPLC da GC na GC, mai da hankali kan zanensu, aikin, da dacewa don bincike daban-daban.

Tsarin zane

HPLC ginshiƙai

Hakkokin HPLC yawanci yana gajarta kuma yana ƙaruwa fiye da igiyoyin GC. Yawancin lokaci suna zuwa 30 cm tsayi kuma suna da diamita na ciki daga 2.1 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm zuwa 8 mm. Facking a cikin ginshiƙan HPLC ya ƙunshi kananan barbashi (yawanci ƙasa da 5 microns a diamita) wanda ke ba da babban yanki don yin hulɗa tare da abubuwan samfuran. Abubuwan da ke tattare da abubuwan da aka shirya na waɗannan abubuwan da ke ba su damar haɓaka mahimman mahadi dangane da kaddarorin sunadarai.

Babban fasali:

Tsawon: Har zuwa 30 cm

Diamita: Yawanci tsakanin 2.1 mm da 8 mm

Kayan marufi masu falle: kananan barbashi (e.g. silica) tare da gyare-gyare daban-daban waɗanda suka dace da ƙimar rabuwa daban-daban (misali al'ada).

GNC ginen GC

GC columns, by contrast, are longer and narrower, typically up to 100 m in length and have an internal diameter ranging from 0.1 mm to 1 mm. Ana iya raba su cikin nau'ikan manyan nau'ikan guda biyu: cakulan columns da tsararren ginshiƙai. Cikakken ginshiƙai suna dauke da wani sashi mai tsayayyen tsari ko kuma mai da hankali a kan tallafi mai kyau, yayin da ginshiƙi mai kyau suna da fim ɗin bakin ciki a jikin bango na tsakiya.

Babban fasali:

Nau'in: cakulan ginshiƙai (m ko ruwa mai tsayi) da kuma capillary ginshiƙi (bude tubular tsarin).

Aikin hannu

Babban aikin chromatography

A cikin HPLC, lokacin hannu shine yawanci sauran ruwa ko cakuda polar ko abubuwan da ba su da ba. Hanyoyin gama gari sun haɗa da ruwa, methanol, acetomeitrile, da kuma wasu buffers. Zabi na Mobile yana da mahimmanci saboda yana shafar hulɗa tsakanin mai bincike da kuma lokaci na tsaye a cikin shafi.

Gas Chromatography

GC yayi amfani da matattarar hannu na gcarous, mafi yawanci ana saba da iskar gas kamar helium ko nitrogen. Samfura dole ne ya kasance mai isasshen isa ya ƙafe lokacin da aka gabatar a cikin shafi. Wannan buƙatun yana nufin cewa GC shi ne da ya dace da nazarin mahaɗan volatile, yayin da HPLC na iya ɗaukar kewayon abubuwa, gami da mahaɗan marasa amfani.

Hanyar rabuwa

Babban aikin chromatography

HPLC ya raba mahadi dangane da kusanci ga tsararren dan wasan zuwa Mobile Pas. Ana iya amfani da nau'ikan wurare daban-daban na chromatographagen:

Ragewa na Karo: Aikin Nunin Nuna tare da Polar Mobile Pas.

Lokaci na al'ada na al'ada: Polar heainy wani lokaci tare da Mobile Mobile.

Ion musayar chromatography: raba nau'in caji dangane da hulɗa tare da cajin lokaci mai caji.

Girma girman cromogography: ware kwayoyin halitta dangane da girman.

Gas Chromatography

A cikin Chromatography, rarrabuwar kawunan da aka samu da farko a cikin yanayi da kuma tafasasshen abubuwan da aka yi. Hadarin da ke fitar da sauƙin ɗauka daga shafi na farko, yayin da ƙasa da mahaɗan masu zuwa zasu ɗauki dogon lokaci don wucewa ta. TAKARWA tsakanin masu bincike kuma farashin mai na iya cutar da lokaci.

Sensivity da ƙuduri

HPLC Sendurity

HPLC gabaɗaya tana da mafi girman hankali ga mahaɗan da ba mai canzawa ba saboda yana da damar bincika ƙananan taro na samfurori ba tare da ruwa ba. Yin amfani da ƙaramin tsire-tsire masu girma a cikin HPLC na HPLC na samar da yanki mafi girma don hulɗa, wanda ke inganta ƙuduri.

Gc na gc

Tun da yake tunda gas Chromatography na iya maida hankali ne ta hanyar Expaporation, zai iya samun babban hankali ga mahadi mahadi. Cikakken ginshiƙai gaba ɗaya suna da mafi kyawun ƙuduri fiye da ginshiƙan da aka cushe saboda tsawon lokacinsu da ƙananan diamita.

Aikace-aikacen HPLC da GC

Aikace-aikacen HPLC

Ana amfani da HPLC a cikin fannoni daban-daban saboda yawan ƙarfinsa:

Binciken magunguna: An yi amfani da gwajin tsarin miyagun ƙwayoyi da ingancin inganci.

Gwajin muhalli: nazarin gurbata cikin ruwa da kuma samfurori ƙasa.

Gwajin aminci na abinci: gano gurbata da tabbatar da ingancin abinci.

Ka'idojin kimiya: Tsallake sunadarai da kuma nucleic acid.

Aikace-aikacen Churomatography Aikace-aikacen

GC da farko ana amfani dashi don bincika mahaɗan volatile:

Binciken muhalli: auna volatile na kwayoyin halitta a cikin gurbata iska da ruwa.

Nazari da masu binciken oroma: gano abubuwan da ke cikin gida a cikin abinci.

A taƙaice, HPLC da GC fasahohin chromatographic ne waɗanda suka dace da nau'ikan nazarin da ke bisa ga tsarin ƙirarsu, Ajiyayyen lokaci, tsarin rabuwai, aikace-aikace, somaturity, da kuma damar yanke hukunci. HPLC ta dace da mahaɗan labile ko mahimman labulan da ke buƙatar sashen hannu na ruwa, yayin da GC Excels a nazarin volatives ta amfani da matattarar kayan ado. Fahimtar wadannan bambance-bambance suna ba masu bincike damar zaɓar hanyar da ta dace don takamaiman bukatunsu na musamman, tabbatar da cikakken sakamako a fannoni daban-daban.
