What Is Surface Analysis?

What Is Surface Analysis?

Surface analysis is an analytical technique to elucidate elemental composition, chemical state, and micro structure from material surface layer (several nm to several µm). As phenomena such as corrosion, wear, adhesion, and reactions that impact performance and reliability occur primarily on the surface, surface analysis is vital for material evaluation, quality control, and failure analysis.

COSY/TOCSY Analysis│Interpreting spin correlations using 2D NMR

COSY/TOCSY Analysis│Interpreting spin correlations using 2D NMR

In this article, we explain the basic principles and analysis methods of COSY and TOCSY, which are representative techniques of 2D NMR. Starting from confirming correlations between adjacent protons using COSY, we introduce spin network analysis with TOCSY and analysis of carbohydrate using 1D and 2D TOCSY, with concrete examples.

Basics of NOE/NOESY: Causes and Solutions When NOE Is Not Detected

Basics of NOE/NOESY: Causes and Solutions When NOE Is Not Detected

NOE (Nuclear Overhauser Effect) is an important NMR measurement technique that can reveal spatial proximity relationships within molecules. In this column, we discuss the difference between difference NOE, 1D NOESY, and 2D NOESY, and how to select each method, the relaxation time that is key for analysis. The causes and solutions for cases when NOE is not detected are also covered. Moreover, we answer the frequently asked questions and explain the key points for effective use of NOE measurement.
