Study Notes

Gin tic me acel me Spektrofotometri UV-Vis

  • Spektrofotometri UV-Vis obedo me tic me ngolo jami ma moko i labol kun lube ki kit ma jami magi gitye kwede ka ce tye jami ma neno lok me electromagnetic.
  • Tim tic man cung ne i kom tam me gweno mac me taratara ma molekul onyo ion gweno i labol i borrwom me piny ma okato ange.
  • Mac ma kitiyo kwede kwanyo:
    • Ultraviolet (UV): 200–380 nm
    • Visible (Vis): 380–700 nm
    • Inframerah (IR): 700–3000 nm
  • Borrwom me piny kinyuto ki alama λ (lambda).
  • Kit ma piny nen kwede nyuto wat ma tye i kin borrwom me piny gin ki gweno onyo lo mac me labol.

Kit ma Spektrofotometri UV-Vis Tic kwede

  • Tim tic madit me spektrofotometri UV-Vis obedo miyo elektron dok malo ki kabedo ma iting ikome (ground state) dok i kabedo ma iting ikome makato (excited state) pien gwenyo mac me UV onyo Vis.
  • Ground state: Kabedo ma elektron bedo iye ma peya obedo ka gweno teko.
  • Excited state: Kabedo ma elektron odongo iye iting ikome ka gweno teko ki i mac me UV-Vis.
  • Ka mac kato ki i labol, taratara mogo bigweny, dok taratara mogo bidong ka kato.
  • Dwe me mac ma kigweno pire tek tutwal ki dwe me jami ma tye i labol.

Pot Pot Madongo me Spektrofotometer UV-Vis

  • Spektrofotometer UV-Vis tye ki pot pot madongo mogo me ngolo dwe me gweno onyo lo mac me labol:
    • Mac ma Medo Tere
      • Medo mac me UV gin ki Vis
      • Kit me mac ma medo tere
        • Lamu me Deuterium (UV): 190–380 nm (ticce romo nino 500)
        • Lamu me Tungsten-Halogen (Vis & Near IR): 350–2200 nm (ticce romo nino 1000)
        • Lamu me Mercury: Kitiyo kwede me yubo borrwom me piny (365 nm)
    • Monokromator
      • Ticce obedo me poko mac me polikromatis me doko mac me monokromatis (borrwom me piny acel keken).
      • Tye ki:
        • Prisma: Me poko mac.
        • Kisi Difraksi (Grating): Poko mac kun lubo rwom me borrwom me piny.
        • Celah Optik: Tiro mac ma opokere otera i labol.
    • Cuvette
      • Agulu ma nen tere me keto labol iye.
      • Jami ma cuvette otedo kiye cung ne i kom borrwom me piny ma kitiyo kwede:
        • Kuarsa: Pi UV
        • Gelas/Plastik: Pi Vis
      • Kit me cuvette:
        • Single Beam: Yo mac acel kato ki i cuvette acel.
        • Double Beam: Yo mac aryo, acel pi labol dok acel pi ma kinyutiye, miyo tic me ngolo dwe odong maber.
    • Detektor
      • Loko mac ma labol oloyo me doko sinyal me latrik.
      • Kit me detektor:
        • Photodiode
        • Photomultiplier Tube (PMT)
    • Readout/Display
      • Nyuto atematema ma kilwongo kun lube ki gweno, lo mac, onyo dwe me jami ma tye i labol.

Kit me Ngolo Jami ma Tye i Spektrofotometri UV-Vis

  • Ngolo Jami ki Kiyo
    • Kun lube ki borrwom me piny madit (λmax) ka gweno oting ikome otime.
    • Pok jami ma kitgi pat kun lube ki kit ma en gwenyo mac kwede.
  • Ngolo Dwe me Jami
    • Kun kitiyo ki cik me Lambert-Beer:
      • A = εbc
        • A: Gweno (Absorbansi)
        • ε: Koefisien me gweno me molar
        • b: Bor me yo me mac (cm)
        • c: Dwe me yugi (mol/L)

Jami ma Kilwongo i Spektrofotometri

  • Gweno (A)
    • Dwe me mac ma labol ogweno.
    • Dwe me gweno: 0 – 1
  • Lo Mac (%T)
    • Percente me mac ma labol oloyo.
    • Dwe me lo mac: 0% (mac ogweny woko) – 100% (mac oloyo woko)
    • Wat ma tye i kin gweno gin ki lo mac:
      • A = -log(T)

Mac ma Kiweko i Spektrofotometri

Kit me Monokromator

  • Prisma: Poko mac kun lube ki kit me gobo mac.
  • Kisi Difraksi (Grating): Poko mac kun lube ki kit ma polge atung atung kwede.
  • Celah Optik: Tiro mac me monokromatis otera i labol.

Kit ma Spektrofotometri UV-Vis Kitiyo Kwede

  • Ngolo dwe me jami i yugi.
  • Ngolo jami kun lube ki kit ma en gwenyo mac kwede.
  • Ngolo kit ma jami leng kwede.
  • Kitiyo kwede i pot pot mapat pat calo kemical me ngolo jami, faramasi, biokemical, gin ki kabedo.
