Typical uses of XRF include the analysis of petroleum oils and fuel, plastic, rubber and textiles, pharmaceutical products, foodstuffs, cosmetics and body care products, fertilizers, geological materials, mining feeds, slags and tails, cement, heat-resistant materials, glass, ceramics, catalysts, wafers; the determination of coatings on paper, film, polyester; metals and alloys, glass and plastic; forensics; multi-layer thin films on silicon wafers, photovoltaics and rotating storage media as well as pollution monitoring of solid waste, effluent, cleaning fluids, pools and filters. In addition, X-ray Transmission ( XRT) process gauges are employed to measure sulfur ( S) in crude oil and marine bunker fuel.

XRF spectrometers are the elemental analysis tool of choice, for many applications, in that they are smaller, simpler in design and cost less to operate than other technologies like inductively coupled plasma optical emission spectroscopy ( ICP-OES) and atomic absorption ( AA) or atomic fluorescence ( AF) spectroscopy. Examples of some common EDXRF applications are: Cement and raw meal: sulfur, iron, calcium, silicon, aluminum, magnesium, etc; Kaolin clay: titanium, iron, aluminum, silicon, etc; Granular catalysts: palladium, platinum, rhodium, ruthenium, etc; Ores: copper, tin, gold, silver, etc; Cement and mortar fillers: sulfur in ash; Gasoline, diesel and RFG: sulfur, manganese, lead, etc; Residual gas oils: sulfur, chlorine, vanadium, nickel, etc; Secondary oil: chlorine, etc; Kerosine, naphtha: sulfur, etc; Crude oil and bunker fuels: sulfur, vanadium, nickel, etc; Plating, pickling & pre-treatment baths: gold, copper, rhodium, platinum, nickel, sulfates, phosphates, chlorides, etc; Acetic acid: magnesium, cobalt and bromine; Terephthalic acid ( TPA) : cobalt, manganese, iron, etc; Dimethyl terephthalate ( DMT) : heavy metals; PVC copolymer solutions: chlorine; Photographic emulsion: silver; Clay: metals and non-metals; Waste and effluent streams: RCRA metals, chlorides, phosphates, etc; Food, pet food and other animal feed: potassium, phosphorus and chlorine; Cosmetics: zinc, titanium, calcium, manganese, iron, silicon, phosphorus, sulfur, aluminum, and sodium; Wood treatment: CCA, Penta, ACQ, ACZA, phosphorus-based fire retardants, copper naphthanate, zinc napthanate, TBTO, IPBC and combinations of these; Antacids: calcium; and Toothpaste: phosphorus and tin.

tipe XRF termasuk analisis dari minyak bumi dan bahan bakar, plastik, karet dan tekstil, produk farmasi, makanan, kosmetik dan produk perawatan tubuh, pupuk, bahan geologi, feed pertambangan, terak dan ekor, semen, bahan tahan panas, kaca , keramik, katalis, wafer, penentuan lapisan pada poliester kertas, film; logam dan paduan, kaca dan plastik; forensik, multi-lapisan film tipis pada wafer silikon, photovoltaics dan media penyimpanan berputar serta pemantauan pencemaran limbah padat , limbah, membersihkan cairan, kolam dan filter. Selain itu, sinar-X Transmisi ( XRT) pengukur proses yang digunakan untuk mengukur belerang ( S) dalam minyak mentah dan bahan bakar bunker laut.

Spektrometer XRF merupakan alat analisis unsur pilihan, untuk aplikasi banyak, bahwa mereka lebih kecil, sederhana dalam desain dan biaya lebih sedikit untuk mengoperasikan dibandingkan dengan teknologi lain seperti induktif coupled plasma spektroskopi emisi optik ( ICP-OES) dan serapan atom ( AA) atau fluoresensi atom ( AF) spektroskopi. Contoh beberapa aplikasi EDXRF umum adalah: Semen dan makan mentah: belerang, besi, kalsium, silikon, aluminium, magnesium, dll; Kaolin clay: titanium, besi, aluminium, silikon, dll; katalis Granular: paladium, platinum, rhodium, ruthenium , dll; Bijih: tembaga, timah, emas, perak, dll; Semen dan pengisi mortir: sulfur dalam abu, Bensin, diesel dan RFG: belerang, mangan, timah, dll; minyak gas Residual: belerang, klor, vanadium, nikel, dll, minyak Sekunder: klorin, dll; Kerosine, nafta: belerang, dll; minyak mentah dan bahan bakar bungker: sulfur, vanadium, nikel, dll; Plating, acar & pra-perawatan mandi: emas, tembaga, rodium, platina, nikel, sulfat, fosfat, klorida, dll; asam asetat: magnesium, kobalt dan bromin; asam tereftalat ( TPA) : kobalt, mangan, besi, dll; Dimetil tereftalat ( DMT) : logam berat; PVC kopolimer solusi: klorin; emulsi Fotografi: perak ; Clay: logam dan non-logam; Limbah dan aliran efluen: logam RCRA, klorida, fosfat, dll; Makanan, makanan hewan dan pakan hewan lain: kalium, fosfor dan klorin; Kosmetik: seng, titanium, kalsium, mangan, besi, silikon, fosfor, belerang, aluminium, dan natrium, pengobatan Kayu: CCA, Penta, ACQ, ACZA, fosfor berbasis penghambat api, naphthanate tembaga, seng napthanate, TBTO, IPBC dan kombinasi ini; Antasida: kalsium, dan Pasta gigi: fosfor dan timah.
