  • What is the refractive index of Pam solution?
  • The refractive index of PAM solution increases with the increase of temperature, and the values of refractive index of PAM solution are in the range of 1.32–1.38. 1. Introduction
  • What are the refractive index increments of polyacrylamide?
  • The refractive index increments of polyacrylamide for various wavelength were determined both in the usual solvents (water, ethylene glycol, formamide) and in those so far unused (ethanolamine, dimethyl sulfoxide). The values thus obtained are compared with the reported data. The necessity to employ anhydrous polyacrylamide samples is stressed.
  • What is the optical properties of polyacrylamide (PAM) solution?
  • The optical properties of polyacrylamide (PAM) solution play an important role in measuring PAM concentration of the solution in the polymer flooding of oilfield based on optical methods. Transmittance cm −1 °C by an infrared spectrometer) relation.
  • What is a specific refractive index increment?
  • Chromatographia. 2017 Jun; 80 (6): 989–996. The specific refractive index increment (∂ n /∂ c) is an essential datum for the accurate quantitation of molar mass averages and distributions ( inter alia) of macromolecules when refractometry, static light scattering, and/or viscometry detection are coupled on-line to size-based separation techniques.
