And the bio-oil was analyzed by elementary analysis, Fourier transform infrared spectroscopic analysis (FT-IR) and gas chromatography mass spectrometry (GC MS).
Metallo-molecular systems were characterized by elementary analysis, spectral techniques (FT-IR, ESI-MS) and evaluated in terms of their magnetic properties.
The macromolecular structure of the resulting copolymers was wholly characterized by elementary analysis, IR, UV vis, high-resolution 1H NMR, and solid-state high-resolution 13C NMR.
The formation and composition of four new IPECs between EPO and L100-55 westablishedshed by elementary analysis.
The catalysts were characterized by elementary analysis, X-ray diffraction (XRD), transmission electron microscopy (TEM) coupled by EDS and X-ray photoelectrons spectroscopy (XPS).
It is recommended to obtain this value by elementary analysis.
The basis is the carbon content is the TOC used in a 500 ml batch; this must be previously determined e.g. by elementary analysis.

Although the overall degree of sulfation can be easily determined by elementary analysis (i.e., by the determination of the sulfur content of a GAG sample), a more detailed structural analysis of the sulfation pattern is a challenging task.
