Elemental analysis. A LECO CHNS-932 elemental analysis
apparatus was used to determine the amount of C and N in chitosan.
In this case, samples were heated to a temperature of 1000 C and
approximately 2 mg of chitosan was placed inside a silver capsule
and dropped into the CHNS-932 furnace, where it was completely
combusted. This instrument relies upon infrared detection to measure
the weight percent of carbon, while nitrogen was measured by
thermal conductivity detection. The DD of chitosan was determined
by the formula below (Kasaai, Arul, & Charlet, 2000):
