(FTIR) Start-Up Inspection - IRAffinity-1 series

• Dry Indicator Check(This check must be done before turning ON.)

• Silica Gel Check(This check must be done before turning ON.)

The color of Silica gels turns into red from blue as they absorb moisture. They should be replaced when the color has become lavender color (purple).

• Power Spectrum Check

FTIR performance is evaluated by measuring the power spectrum. The power spectrum gives the intensity at various wavenumbers. After ensuring that the sample chamber is empty, enter the following parameters in the Parameter Tab, and measure the power spectrum to verify the specifications.

  • Measuring mode: Power
  • Resolution: 2 cm^-1
  • Range: 4700 to 340 cm^-1
  • N scans: 45 scans
  • Apodization: Happ-Genzel

  • Detector: standard
  • Neam: internal
  • Detector speed: 2.8 mm/sec

  The intensity specifications are given below.

   

    *）There is an absorbance peak of water at 400 cm⁻¹, so correct intensity of the power spectrum is not calculated. Thus the intensity of 403 cm⁻¹ is used for evaluation of the power spectrum.

    

If the intensity does not meet the specifications, or the energy at high wavenumbers (to 4600 cm⁻¹) is extremely low, run [Auto adjustment], and reanalyze the spectrum. If the power spectrum does not improve after the "auto adjustment", the system may be damaged; contact a Shimadzu sales or service representative. If the power spectrum intensity at all wavenumbers is close to zero, the light source may be disconnected.
Contact a Shimadzu sales or service representative, if the light source is disconnected. Light source replacement should be performed by our service personnel.

 

The validation program inspects the FTIR condition instead of Power spectrum check.
IRAffinity-1 series provides the validation programs according to the Japanese Pharmacopoeia, European Pharmacopoeia, Chinese Pharmacopoeia and ASTM.
