Ingano ya SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, na K₂O irakenewe kugira ngo hagenzurwe neza imiterere y'ibicuruzwa no kubahiriza amategeko. Ibikoresho bya Lonnmeter XRF bitanga ibipimo nyabyo kandi bitaziguye by'ibi bice by'ingenzi.
Isesengura risanzwe rigaragaza ihindagurika rya 0.01 wt% kuri oxyde nini, rituma abakora ibintu bagumana urwego rw'ibice bigize ikirahure. Urugero rwa Na₂O cyangwa CaO rudafite ubushobozi rushobora guhindura uburyo ubushyuhe budashobora kugabanuka, ubwumvikane, no kuramba. Gucunga neza bigabanya kwangwa kw'itsinda bitewe n'ibara ritari ryemewe cyangwa kwangirika kwa mekanike.

Imiterere y'ikirahure: Ibintu n'Ibintu bitandukanye
Ibirahuri birenga 70% bigizwe na silica (SiO₂), bitanga ubukana bw'imiterere n'ubudahangarwa bw'imiti. Soda (Na₂O), ubusanzwe 12–15%, igabanya ubukana bw'ishongeshwa, bigatuma ubushobozi bwo gukora burushaho kuba bwiza. Lime (CaO), hafi 9–12%, yongera ubukana n'ubudahangarwa bw'imiti. Alumina (Al₂O₃) kuri 1–3% yongera imbaraga za mekanike kandi ikongera ubushyuhe. Magnesia (MgO) na potashi (K₂O) bikoreshwa mu rugero ruto kugira ngo bitunganye ubukana n'imiterere y'ubuso. Oxyde y'ubutare (PbO), iyo iri hejuru ya 24%, itanga igipimo cyo hejuru cyo kugarura ubushyuhe n'ubucucike bwinshi, bikaba ari ingenzi ku kirahuri cy'amatara n'ubutare bw'ubutare.
Ingano y'ibikoresho igaragazwa n'ibi bintu bigize ikirahure. Ikirahure cya soda-lime ni cyo cyiganje mu musaruro mpuzamahanga bitewe n'imiterere ya mekanike n'iya chimique iringaniye. Ikirahure cya borosilicate, kirimo 10–13% B₂O₃, gituma ubushyuhe buke bukwirakwira, bikaba ingenzi mu ikoreshwa rya laboratwari n'ibikoresho byo guteka. Ikirahure cya lisansi gishyira imbere ubwiza bw'urumuri n'ububengerane ku bikoresho byo ku meza. Ibikoresho bisimbura ikirahure cya aluminosilicate byongera Al₂O₃ kugira ngo birambe mu bidukikije bikomeye. Imikorere ya buri bwoko bw'ikirahure ishingiye ku kugenzura neza imiterere y'ibikoresho by'ikirahure.
Amasaro y'ikirahure avanze, ibinure by'ikirahure, n'ikirahure cy'ifu
Amasaro y'ibirahure avanze atanga uburinganire bwinshi n'ihindagurika rito, atanga ibisubizo nyabyo mu isesengura ry'ibice bya XRF ku ikorwa ry'ibirahure. Matrix yabo ihoraho ikuraho imiterere mito y'ibirahure, bigatuma hagaragazwa neza SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, na K₂O.
Udupira tw’ibirahure dukora nk'ibikoresho byizewe byo kugenzura ubuziranenge bw’ibirahure. Bifasha mu gusesengura vuba imiterere y’ibirahure kandi bigafasha mu kumenya itandukaniro ry’ibirahure cyangwa ubwandu muri laboratwari za QA/QC. Udupira tw’ibirahure dukomeza kuba ibintu by’ingenzi mu miterere y’ibirahure, bigatuma habaho gushakisha neza ibirahure mu gihe cyose bikorerwa.
Ikirahure cy'ifu gishyigikira imiterere yo gusiga, gusya, guhuza imiti, kongera gukoresha, kandi bigafasha kwihutisha imvange. Ingano y'uduce twacyo twiza ituma ibice by'ingenzi bihuzwa neza, bikaba ari ingenzi mu gutegura icyitegererezo. Ikoreshwa ry'ikirahure cy'ifu rigera ku mikorere n'iterambere ry'ibicuruzwa, rigatuma habaho gukurikirana neza imiterere y'ibikoresho by'ikirahure no gushyigikira isesengura rya XRF ritaziguye kandi ryimbitse.

Igenzura ry'Ubuziranenge mu Ikorwa ry'Ikirahure
Igenzura ry’ubuziranenge bw’ibirahure rishingira kuri XRF kugira ngo hagenzurwe ibintu byinshi, byemezwa ko bihuye neza kandi birinda kwandura. Sisitemu za Lonnmeter XRF zipima Si, Na, Ca, Mg, Al, K, Pb, n’ibindi bintu by’ingenzi mu masegonda ari munsi ya 60. Uburyo bwo gusesengura bwa TXRF bupima ibintu by’ingenzi n’ibikurikira, nka Mn, Ni, Cu, Zn, na Sr, kugeza ku rugero rwa sub-ppm.
Gukurikirana ibintu bifatika birinda amabara adakenewe n'intege nke za mekanike. Gutahura ubunini bwa Fe, Ti, na Pb bishyigikira imiterere y'urumuri kandi bigakuraho ibyago bituruka ku bintu bikubiye mu bipimo cyangwa aho ibintu bikomerera. Gupima ibice by'urumuri, bifashishwa na XRF-CT igezweho n'uburyo bwo gufunga, bigenzura imiterere y'ahantu ku rupapuro cyangwa ikirahuri cyabumbwe, bikaba ari ingenzi mu gukora ibintu binini.
Ibikoresho bya XRF byoroshye kandi biri mu murongo byikora ku buryo bworoshye, bigahuza ibisubizo mu kugenzura ibikorwa mu buryo bwihuse. Ubu buryo bunoza ubwiza bw'ibirahuri, bushyigikira imiterere y'ibicuruzwa no gusubiza ako kanya ku buryo butari bwo.
Uburyo bwo Kumenya no Gutandukanya Ubwoko
Ubwoko bw'uburyo bwo kumenya ikirahure burimo gupima ibikumwe bya XRF, gupima ubucucike, no gusuzuma igipimo cya refractive index. Gupima ibikumwe bya XRF bitanga ishusho itaziguye kandi idasenya ibintu byose by'ingenzi bigize ikirahure, bigatuma hamenyekana Si, Na, Ca, Mg, Al, Pb, na K hamwe n'ubushobozi bwo gusubiramo munsi ya 3% RSD. Ibipimo by'ubucucike bifasha gutandukanya imiterere y'ibikoresho by'ikirahure bifite itandukaniro kuva kuri 2.2 g/cm³ (soda-lime) kugeza kuri 3.1 g/cm³ (ikirahure cya lead). Isuzuma ry'igipimo cya refractive index ritandukanya neza ikirahure cya soda-lime, borosilicate, n'ikirahure cya lead; agaciro gasanzwe ka nD kari hagati ya 1.51 na 1.70.
Isesengura ry'imibare ryongera ubuziranenge bwo kumenya. K-bivuze gushyira hamwe ibice by'ibirahure hakoreshejwe amakuru menshi ya XRF, bishyigikira igipimo cyo guhuza icyiciro cy'ubushakashatsi kiri hejuru ya 95%. Isesengura ry'umukara ritandukanya impinduka nto ariko zigaragara hagati y'ibice cyangwa ubwoko butandukanye. Modele za shimi zigabanya imiterere y'ibirahure (urugero: amasaro y'ibirahure avanze ugereranyije n'ibirahure bivanze) hakoreshejwe ibikumwe by'ibanze bifite ubuziranenge burenze 98% iyo bihujwe n'amakuru ya XRF.
Igenzura ry'Ubuziranenge mu Gukora Ikirahuri
Kwemeza ubuziranenge bw'ikorwa ry'ibirahure biterwa no gupima byihuse kandi neza ibintu byinshi. Abasesenguzi ba XRF bakorerwa kuri interineti na laboratwari bagenzura imiterere y'ibikoresho by'ibirahure mu masegonda make. Itara rya X-ray rigaragaza SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, na K₂O, bifasha kugenzura ibintu bigize ibirahure n'uburyo bingana.
Dukurikije amakuru y’inganda, XRF igera ku mupaka wo kuyimenya kugeza kuri 1 ppm ku bintu bito, bigatuma haboneka ibintu bihumanya ikirere bigira ingaruka ku miterere cyangwa ubwiza bw’ibintu. Gushyira mu bikorwa XRF bitanga ibitekerezo bitaziguye ku gukosora ibikorwa, bikongera umusaruro kugeza kuri 15% mu mirongo igenzurwa neza.
Gutondekanya hakoreshejwe ikoranabuhanga bihuza n'umusaruro, bigatuma habaho kugenzura buri gihe imiterere y'ibikoresho by'ibirahure. Ibi bigabanya ihindagurika ry'ibicuruzwa bitandukanye kandi bigakuraho ibicuruzwa bidasanzwe. Gusuzuma ibintu byinshi ni ingenzi mu gusuzuma imiterere y'ibirahure byahujwe, ikoreshwa ry'udupira tw'ibirahure, n'ikoreshwa ry'ibirahure by'ifu. Igenzura ryimbitse rikorwa aho hantu rigabanya igihe cyo kudakora kandi rigatuma habaho gukosora ako kanya, bigafasha ireme ry'ibicuruzwa ku buryo buhoraho.
Ongera uburyo bwawe bwo gusesengura ikirahure
Imashini zisesengura za Lonnmeter XRF zipima neza ibintu by'ingenzi mu miterere y'ibirahuri: SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, K₂O. Ibi bikoresho bitanga uburyo bwo kumenya ibintu byinshi kugira ngo harebwe ubuziranenge bw'ibirahuri bikoreshwe kandi bigenzurwe vuba amasaro y'ibirahuri, uduce duto tw'ibirahuri, n'ibirahuri by'ifu. Kugira ngo usesengure ibirahuri bigezweho, hindura uburyo bwawe.Imashini ya XRFgushyigikira ibisabwa bitandukanye mu gukora ibirahuri no kumenya ibikenewe.
