(FTIR) Power Spectrum Becomes too Small, or Fluctuates

1. Power spectrum becomes smaller than ones when instruments was installed.
2. Power spectrum becomes small in short term (a day to a week). Power spectrum fluctuates.

Reason
  1. Deterioration because of long term use
  2. Trouble with the power board
  3. Trouble with the detector

 

Solution
  1. Deterioration because of long term use
    • Execute the [Auto Adjust] on [Instrument] button.
    • When power spectrum does not fluctuate in short term, execute a Japanese, Chinese or European Pharmacopoeia. The FTIR is normal when validation passes.

  2. Trouble with the power board
    • The power board might be inoperative. Please contact a Shimadzu sales or service representative.

  3. Trouble with the detector
    • The detector is malfunctioning and correct temperature adjustment cannot be done.
