FTIR (2)Questions for FTIR Spectrometer

NoQuestion Answer1How to make FTIR spectrum sharper ?Prepare good samples (not mixed with impurities absorption of light in the survey area)Can set resolution (Resolution) in the Advance of Measument setup.

2How to use FTIR for monitoring used oil?3How to maintain FTIR?If using the ATR: clean surface measurement sample window after each useIf you use the transmittance: clean the chamber after each use, avoid dust in the chamberPreservation equipment in humidity below 60%

4How to identified problem in FTIR and how to solve it?This is the process of automatic test hardware each boot. If any problems part, on the software will have a red or yellow warning depending on condition .- Yellow light :1. the OPUS status light becomes yellow If the desiccant is saturated and cannot further absorb any humidity, it has to be replaced.2. IR source has not yet reached its operating temperature- Red light :Spectrometer malfunction, defective spectrometer component

5Can you tell me about aperture setting in FTIR?Trong phn mm bn vo phn "Help" -> Help Topic. Sau search Aperture s c m t kh y 6How to make optimum setting in FTIR in order to get best result?Can optimize the settings by changing the parameters like Resolution (resolution), scan time (Number is scanned) in position measument Advance in Setup. However changing these parameters will change the pattern scan time.7How to know that polistyrene that we use for Performance Qualification still ok?To check Polystyrene is in good or not? We can only send to the manufacturer for checking. Or an agency that has the device is working correctly for inspection.

8What kind of important spare part that we have to stock?Laser source, IR source,Silicagel.

9What kind of problem that usually happen in FTIR? Normally, the life of laser source 2500h (or about 4 to 5 years). If Weak laser source machine will have a warning, require replacement.Use a long time, silica gel inside the machine (in the back) can be filled with water, less effective. Humidity in the machine rise up too high, it will warning and require replacement. For the machine user and window beam splitter by KBR may be broken or blurred due to intolerable humidity, be replaced.
