How to Analyze Samples Using FTIR

FTIR, or Fourier Transform Infrared Spectroscopy, is a technique used to analyze the absorption spectrum of a given liquid, solid or gas. The advantage of FTIR to standard spectroscopy is the ability to collect data over a wide spectrum rather than a narrow one. Fortunately, analyzing samples using FTIR is just as simple as any other form of spectral analysis.

Things You'll Need

FTIR machine
FTIR spectroscopy software
Kimwipes
Acetone

Instructions

- 1
  Turn on the computer you are using to collect the data and the FTIR apparatus.
- 2
  Clean the sample holder with acetone. This is usually done using Kimwipes as they are delicate and will not scratch the sample holder.
- 3
  Turn on and log into the spectroscopy software installed on the computer.
- 4
  Set up the parameters of the test, usually done using the instrument setup button. In this menu enter the sample name and the range you would like to scan.
- 5
  Collect a "blank" reading of the sample holder. This is usually done by pressing either the "background" or "blank" button in the spectroscopy software.
- 6
  Insert the sample into the sample holder and click "start" to collect your spectrum.
