Imiphumela yomsebenzi inyatheliswa ejelezelwa ama-Analytical Shemistry. Isicupho se-Ion siyisilinda kusuka ku-electrodes. Ngaphakathi, kudalwe amasimu kagesi nezezibuthe, lapho ama-ion of the nto afundwayo ajikeleze.
Kamva kokujikeleza kwama-ion, kungenzeka ukunquma isisindo sabo esinembile. Kule nqubo, kubalulekile ukuthi ama-Ion ajikeleze kakhulu. Futhi kulokhu, insimu kagesi eyakha isicupho nge-elektrodi yayo kufanele ibe yifomu elikhethekile. Le nkambu ibizwa ngegama elihlangene, kanye nezicupho ezihlanganayo ezivumelanisa ezinamandla.
Isicupho sokuqala esivumelanayo (i-DHC) sasungulwa ngo-2011 nguProfesa esikhungweni seSayensi seScience and Engineering Computing Technologies for imisebenzi enemisebenzi emikhulu yedatha (cdise) evgeny nikolaev. Kubizwa kanjalo, ngoba empeleni insimu kuyo ayivumelani, kepha i-ion "kubonakala" ukuthi kungenxa yokujikeleza kwawo ngokushesha.
I-DHC isicupho esihle kakhulu okwamanje ngokunemba kokunquma i-spectrum, ngakho-ke isetshenziswa ngokugcwele kuma-spectrometers amaningi asetshenziswa ezifundweni, ngoba kukhona ukunemba okubalulekile. Ifakwe ku-Mass Spectrometer ene-magrenetic enamandla kazibuthe eLabhorethri kazwelonke yamasimu aqinile kazibuthe, eTallahassee, e-USA.
Ukunemba kokukalwa kwezinqwaba kufanele kukhule ngokuqondile ngokwanda kwensimu kazibuthe (kanye namashumi ezigidi zamadola angamashumi ezigidi zamaRandi). Eqinisweni, kwavela ukuthi ukunemba ngokwanda ngobukhulu bensimu kazibuthe, ngeshwa, akukhulile ngokungaqondile, kepha kuncane kakhulu kunalokho obekulindelwe.
Ososayensi baphakamise ukuthi lokhu kungenxa yokuntuleka kwe-vacuum ogibeni noma ngabe usebenzisa amaphampu aphelele kakhulu. Futhi sakha isicupho sohlobo oluvulekile, okungukuthi, vula kusuka zombili izinhlangothi, ezikuvumela ukuthi ucindezele ngokukhululekile amagesi asele kuwo ukuze ulondoloze i-vacuum edingekayo. Isicupho sabizwa ngeseli le-zig-zag.
"Manje ngelebhu yethu kule divayisi" e-gland "yenziwe. Kuyo sizokwenza ucwaningo bese sihlola ukuthi ukucatshangelwa kwethu kuyiqiniso yini. Kepha uma eyiqiniso - khona-ke isicupho sidalwe futhi sizobuyisela ukuncika okuqondile kokulinganiselwa kwesilinganiso sobuningi kusuka kumandla kazibuthe, okuzonikeza ukunemba okungcono ngamasimu amakhulu kazibuthe. Futhi njengoba ukunemba kukhula ngokukhula kwensimu, lokhu kusho ukuthi isicupho sizovunyelwa ukudala okunembe kunazo zonke kuwo wonke ama-spectrometers akhona, "kusho umfundi othweswe iziqu zeSkoltech u-Anton Loznes.
Ngokusho kwekhanda lokufunda kukaProfesa Evgeny Nikolaev, ama-spectrometers anohlobo olusha oluzokwanda ukunemba kokuhlaziywa kwamasampula ezinto eziphilayo kanye nokuhlanganiswa okungamafutha anjengezinkulungwane ezingama-400.
