Gas chromatography. yiwuwa na da hanyar

Gas chromatography - analysis hanya, samun mai kyau msar tambayar ci gaba. Wannan bincike ta msar tambayar da m tushe da gudummawar na tsawon shekaru goma, saurin ci gaban da wannan dabara.

An sani cewa gas chromatography daban-daban daga wasu hanyoyin da cewa gas amfani a cikinta, a matsayin mobile lokaci. A tsit lokaci zai iya zama mai ɗamfarar ko ruwa. Dangane da wannan shawara adsorption gas ko gas-ruwa chromatography.

The rabuwa garwayayye abubuwa a na'urorin irin matsayin gas chromatograph, shi ne saboda da m maimaitawa na aiwatar da rarraba aka gyara tsakanin tsit ruwa ko m lokaci da kuma wani motsi gas. The rabuwa tsari dogara ne a kan bambance-bambance a volatility da solubility na analytes. Daya bangaren, wanda volatility a ba yawan zafin jiki mafi girma da kuma kasa da solubility na tsit lokaci za ta motsa ta hanyar da shafi sauri.

Amfani da gas a matsayin m mirgina damar samun abũbuwan amfãni kamar rabuwa da bijiro da batun kafa abubuwa tsabta da kuma gudun analysis. Test samfurin da aka gabatar a cikin shafi a gaseous nau'i ko a tururi form. Tare da wannan hanya shi ne zai yiwu mu tantance ba kawai gas amma kuma ruwa da kuma m abubuwa, wanda fassara a cikin so jihar ta dumama. A wannan batun, a gas chromatography da yawan zafin jiki a da dukan tsari, taka wani muhimmanci sosai rawa. Performance iyaka ga gas adsorption analysis Hanyar jeri daga 70 zuwa 600 ° C, da kuma ga gas-ruwa - daga 20 zuwa 400 ° C. Industry samar da wani gas chromatograph, wanda damar shirye-shirye da yawan zafin jiki a gaba.

Wannan hanya ya sa ya yiwu don nazarin wani abu kwayoyin nauyi kasa da 400. Ba su decompose a danshin, kuma ba su canja tsarin a cikin m sandaro.

Yafi a cikin analytical yi amfani da iskar gas-ruwa chromatography. Idan aka kwatanta da gas adsorption yana da wasu abũbuwan amfãni, wanda ake dangantawa da yafi mai fadi da kewayon yiwu tsit ruwa lokaci, da kuma high tsarki da kuma cewa shi ne quite muhimmanci, tare da homogeneity na taya.

Gas chromatography - wani m hanya, halin high daidaito, ji na ƙwarai da ikon sanya aiki da kai. A versatility da kuma sassauci na hanyar amfani domin sanin wani batu da na'urar. Gas chromatography cewa aiki don gwada yawa bincike na samar da unambiguous sakamakon, wadda ba a cikin shakka.

Wannan hanya za a iya magance da dama hikimar tantance matsalolin, rabawa da sanin da rabo daga haši zuwa m tururi matsa lamba. A Hanyar gas chromatography da ake amfani da tsarkakewa sunadarai, tsagawa cikin mutum aka gyara daga cikin cakuda da. Shi ne musamman tasiri a cikin rabuwa da irin wannan abun da ke ciki na abubuwa wanda kasance a cikin wannan aji: Organic acid, alcohols, hydrocarbons.
