Paper Abstract

We have used Fourier transform infrared (FT1R) spectroscopy to evaluate the contamination of stainless steel tubing with inner diameters of less than one mm, and lengths of 25 to 100 mm. We will discuss the development of a non-destructive analytical tech-nique which is sensitive to both organic and inorganic contaminants which may arise during fabrication processes. Experimental results will be compared with theoretical calculations for thin films of hydrocarbon lubricants and metal oxides on metallic surfaces. The main advantages of infrared measurements are their non-destructive nature, ease of application, short measurement times, and the ability to interface the necessary auxilliary optics with existing FTIR instruments. The sensitivity of the technique and its application to the evaluation of current cleaning processes will be presented.
