[NMR analysis blog] Basis on qNMR: Integration Rudiments (Part II)
Basis on qNMR: Integration Rudiments (Part II)
My last post was a basic survey on different measurement strategies for peak areas. Manual methods such as counting squares or cutting and weighing, known as ‘boundary methods’ were introduced for historical reasons. These methods were first used by engineers, cartographers, etc, end then quickly adopted by spectroscopists and chromatographers.
In the digital era, most common peak area measurement involves the calculation of the running sum of all points within the peak(s) boundaries or by other quadrature method (e.g. Trapezoid, Simpson,...

Basis on qNMR: Integration Rudiments (Part I)
First a quick recap. In my last post I put forward the idea that integration of NMR peaks is the basis of quantitative analysis. Before going any further, I would like to mention that, alternatively, peak heights can also be used for quantitation, but unless some special pre-processing is employed (see for example P. A. Haysa, R. A. Thompson, Magn. Reson. Chem., 2009, 47, 819 – 824, doi) measurement of peak areas is generally the recommended method for qNMR assays.
In this post I will cover some very basic rudiments of NMR peak areas...

http://3.bp.blogspot.com/_-MfflvAgRls/SwgqmEW0Y2I/AAAAAAAAAgs/kvnVoDo_Cms/s400/Intro1.jpgWhen I started playing drums, so many years ago, I kept hearing about so-called "Drum Rudiments". By that time, I was too young to realize how important they were and to me, they appear just as boring and repetitive exercises. However, rudiments (basic building blocks or "vocabulary" of drumming) are absolutely essential to master drums (something I have to admit I never achieved :-) )
In the last few years I’ve had the opportunity to meet and interact with many chemists...
