AB  - In this assay, the triple-wavelength overlapping resonance Rayleigh scattering 
      (TWO-RRS) method and the fluorescence quenching method for the quantitative 
      detection of chitooligosaccharides (COS) were developed. In the weakly 
      Britton-Robinson buffer solution, COS interacted with 
      Trisodium-8-hydroxypyrene-1,3,6-trisulfonate (HPTS) to form an ion-association 
      complex of HPTS-COS, which increased the RRS intensities at 321 nm, 430 nm and 
      511 nm and decreased the fluorescence intensities of the system at 512 nm. And 
      the changes in the intensities of both methods were related to the changes in the 
      concentration of COS. Moreover, for the TWO-RRS method, OP-10 made the RRS 
      intensities increased stronger, finally, the three peaks' total was linear to the 
      concentration of COS in the range of 1.00-8.00 mug/mL and the limit of detection 
      (LOD) was 0.247 mug/mL, and for the fluorescence quenching method, the linear 
      range was 0.50-3.50 mug/mL with the LOD of 0.108 mug/mL. Based on these, two new 
      and fast spectral methods with high sensitivity and simplicity for the 
      determination of trace COS had been established. The generation mechanism of the 
      TWO-RRS and the fluorescence quenching was studied. At the same time, the two 
      methods were applied to the determination of COS in health products with 
      satisfactory results.
