Lub ntsiab txhais ntawm Spectrophotometer

Spectrophotometry yog ib tug wavelength los yog absorbance tus ci li tej wavelength khwv yees li, qhov khoom ntawd yog tsom xam yog yuav siv ib los yog quantitative. Yog siv feem ntau wavelength ntau yam: (1) 200 ~ 380 nm uv lub teeb zoo noj, (2) 380 ~ 780 nm pom lub teeb zoo noj, (3) 2.5 ~ 25 microns (raws li nthwv dej ' meter ' andlt; - andgt; 1 ~ 400 cm mus 4000 cm mus andlt; - andgt; 1) infrared cheeb tsam. Ntsuas thiab siv kom ultraviolet spectrophotometer, pom spectrophotometer (colorimeter), infrared spectrophotometer haum atomic spectrophotometer. Xav kom cov neeg thiab precision ntawm xab, txhua yam hauv yus cov nqaij yuav tsum raws li txoj cai hauv cov kev cai lub teb chaws metrological pov thawj los yog txoj cai no qhua, kho lus pov thawj so.
