ISTRAŽIVANJA
Istraživanja unutar laboratorija usmjerena su na primjenu nuklearnih analitičkih tehnika u elementnoj analizi uzoraka. Nuklearne analitičke tehnike se baziraju na spektroskopiji karakterističnih x-zraka pobuđenih u uzorku, pri čemu se pobuda postiže ili izvorom x-zraka (npr. rendgenska cijev ili sinhrotronsko zračenje) ili s ionima MeV-skih energija. Ove tehnike omogućavaju vrlo efikasne i brze kvantitativne elementne analize kako malih, tako i velikih uzoraka (od čestica aerosola do arheoloških objekata).
POPIS TEHNIKA:
• XRF – fluorescencija x-zraka (X-Ray Fluorescence) i micro-XRF,
• PIXE – česticama izazvana emisija x-zraka (Particle Induced X-ray Emission), i micro-PIXE,
• RBS – Rutherford-ovo raspršenje čestica projektila (Rutherford BackScattering),
• PESA – elestično raspršenje protona (Proton Elastic Scattering Analysis),
• PIGE – česticama izazvana emisija gama-zraka (Particle Induced Gamma-ray Emission),
U Laboratoriju se radi fluorescencija x-zraka (XRF) dok se ostale tehnike, za koje su potrebni akceleratorski sustavi, izvode u Laboratoriju za interakcije ionskih snopova Instituta Ruđer Bošković s kojima imamo dugogodišnju uspješnu suradnju.
SVOJSTVA NUKLEARNIH ANALITIČKIH TEHNIKA:
• Multielementnost: od vodika (PESA) do C,O, N (RBS), Na, Mg, Al, Si (PIGE) i svih ostalih elemenata upotrebom XRF i PIXE tehnika,
• Osjetljivost - tipično koncentracije do ppm nivoa a po potrebi i niže,
• Veliki dinamički raspon - od % sve do ppm u istoj analizi,
• Dovoljan vrlo mali uzorak
• Jednostavna priprema uzoraka
• Nedestruktivnost
• Pozicijska osjetljivost, što znači da se na istom uzorku mogu analizirati mali segmenti, ako se očekuje nehomogenost u materijalu – na taj način omogućava se površinsko pa čak i dubinsko elementno mapiranje uzoraka,
PRIMJENA NUKLEARNIH ANALITIČKIH TEHNIKA:
Nuklearne analitičke tehnike se osim u fundamentalnim znanstvenim istraživanjima primjenjuju i u polju zaštite okoliša i zdravlja, industrijskih procesa, ne-destruktivnih testiranja, forenzici i arheološkim straživanjima, itd. Trenutni fokus istraživanja Laboratorija je analiza lebdećih čestica (aerosoli) u svrhu kojeg se provodi kontinuirano višegodišnje uzorkovanje.
