Abstract
Refractive index (RI) detection is a common technique used in chemical and biochemical analysis. Rapid monitoring and refractive detection of ultra small volume samples are in great demand. However, it is still a significant challenge for highly precise and miniature detectors to measure ultra small volume samples. This paper will present a flexible method to record the interference fringes which are caused by backscatter with a new linear CCD; furthermore, it will get the information of refractive index by tracking the displacement of fringes with FFT analysis. With this approach, we have been able to obtain detection limits of 2.44×10− 7 \(\triangle\)n, corresponding to 1.37×10− 6 g/mL.
