Analytical chemistry

Analytical chemistry, rasayan vigyan ke ek hissa hae. Ii chij me chemical ke analyse kare hae. Isme natural aur artificial chij ke chemical component study karaa jaae hae. Iske kae ke khatir chromatography, mass spectrometry, flame test jaise technique ke kaam me laawa jaae hae.

Analytical chemistry, rasayan vigyan ke pahila din se important rahaa, jisse ii paawa jaawe sakat rahaa ki ek chij me kon-kon element aur chemical hae. Ii time me analytical chemistry ke khaas yogdaan me rahaa Justus von Liebig se development of systematic elemental analysis aur systematized organic analysis based on the specific reactions of functional groups.Template:Fix/category^{[citation needed]}

Pahila instrumental analysis ek flame emissive spectrometry rahaa, jiske Robert Bunsen aur Gustav Kirchhoff suruu kare rahin, aur jon rubidium (Rb) aur caesium (Cs) ke 1860 me paawe rahin.^[1]

Analytical chemistry me sab se jaada pagriti took 1900 ke baad bhais rahaa. Ii time me, instrumental analysis dhire-dhire field me jaada kaam me laawe jaae lagaa rahaa. Dher basic spectroscopic aur spectrometric techniques ke 20th century ke suruu me paawa gais rahaa aur 20th century ke ant talak refine karaa gais rahaa.^[2]

Separation vigyan ke pagriti yahii rakam ke time line ke follow kare hae aur jaada transform hoe gais , high performance instruments se.^[3] 1970s me isme se dher technique ke saathe kaam me laawe jaawe lagaa, jiske "hybrid techniques" bola jaawe hae, ek sample ke ke characterization ke complete kare ke khaatir.Template:Fix/category^{[citation needed]}
