Thawj pawg spectrometer - keeb kwm hu ua parabola spectrograph - tau tsim nyob rau hauv 1912 los ntawm J. J. Thomson, paub zoo tshaj plaws rau nws qhov kev tshawb pom ntawm cov hluav taws xob hauv xyoo 1897. Nws tau siv lub tshuab ntsuas huab cua los nthuav tawm thawj cov pov thawj rau qhov muaj nyob ntawm cov isotopes uas tsis yog radioactive.
Leej twg tsim pawg spectrometer?
Nyob rau xyoo 1932, Kenneth Bainbridge tau tsim lub tshuab ntsuas huab cua nrog lub zog daws teeb meem ntawm 600 thiab qhov txheeb ze qhov tseeb ntawm ib feem ntawm 10, 000.
Leej txiv ntawm Mass Spectroscopy yog leej twg?
Ib tug tuaj yeem pom los ntawm ob peb nqe lus no tias kev tsim keeb kwm ntawm huab hwm coj spectroscopy tau koom nrog ntau tus kws tshawb fawb. Txawm li cas los xij, qhov tseem ceeb tseem ceeb tseem ceeb: ib qho tsis tuaj yeem ua rau tsis txaus siab los ntawm kev koom tes zoo heev los ntawm Thomson, Nobel Laureate ntawm 1906 thiab leej txiv ntawm huab hwm coj spectroscopy.
Dab tsi yog pawg spectrometry siv rau?
Mass spectrometry yog ib qho cuab yeej tshuaj ntsuam siv tau rau kev ntsuas qhov loj-rau-them piv (m / z) ntawm ib lossis ntau lub molecules tam sim no hauv tus qauv. Cov kev ntsuas no feem ntau siv tau los xam qhov hnyav molecular ntawm cov qauv piv txwv ib yam nkaus.
Yuav siv ntau npaum li cas hauv lub ntiaj teb tiag?
Cov ntawv thov tshwj xeeb ntawm huab hwm coj spectrometry suav nrog kuaj tshuaj thiab tshawb pom, kuaj pom cov khoom noj paug, tshuaj xyuas cov tshuaj tua kab, kev txiav txim siab isotope piv, kev txheeb xyuas cov protein, thiab carbon dating.
