Examples（review of a report）
|
The following example is part of our review of a chemical analysys company's report on molecular structure analysis.
| |
For a commercially available curing agent, we reviewed of a report on molecular stracture analysis by a major analysis company.
The company inferred from measured data of NMR, MALDI-MS, GCMS that a molecular stracture was in a following Figure.
But the molecular structure was incorrect. For example, The peak of 3.3 ppm in the NMR spectrum was not assigned and each peak area was in conflict with the molecular stracture.
We analyzed the same data and revealed the correct stracture of the agent, but the structure is not disclosed on the web.

Examples（molecular structure analysis）
|
The followings are analysis examples of relatively simple molecular structure for us.
R (1,2 ・・・) and x, y, m, n, o etc. are abstractly expressed on this homepage, but those will be expressed concretely in our report.

This structure was analyzed by 1H-NMR and Py-GCMS.
Perfluoropolyether (PFPE) |
This structure was analyzed by 1H-NMR,13C-NM and19F-NMR.
R1 and R2 are different alkyl functions, R3 is PEO(polyethylene oxide) derivative.
This structure was analyzed by 1H-NMR,13C-NMR and 29Si-NMR.
The reaction product of hexamethylene diisocyanate, isophorone diisocyanate, 2-hydroxyethyl acrylate and glycerol dimethacrylate. This structure was analyzed by1H-NMR, 13C-NMR, H-H COSY, HSQC and Py-GCMS.
