Origin of Chemical Shifts

It is common to mention the frequency of an NMR instrument instead of its field. When someone says: I have in my laboratory a 100 MHz instrument, it means that a spectrometer where the protons precess with a frequency of 100 MHz (Lamour frequency) is available in the lab…

DEPT: A tool for 13C peak assignments

Distortionless Enhancement by Polarization Transfer (DEPT) is a double resonance pulse program that transfers polarization from an excited nucleus to another – most commonly 1H → 13C. This results in a sensitivity enhancement relative to the standard decoupled 1D carbon spectra (13C), which benefits only from the small Nuclear Overhauser Effect (NOE) enhancements.

Quantifying Battery Additives with the 60PRO

In this ever-evolving world where technology and science keep pushing into new territory, new inventions are being made and state-of-the-art validation methods are being developed. Over the last few decades, lithium-ion batteries have gained more and more traction in their uses, moving from general simple batteries used for powering your calculator or phone, to cars and trucks, and even airplanes (currently only the small ones). However, as simple as batteries may seem, a lot of work must be done behind to scenes to develop these subtle but priceless additions to our lives.

Why does NMR have an inherently low sensitivity?

It is well known that NMR analysis requires a higher concentration of analyte than any other spectroscopic method. For example, UV-Vis requires an analyte concentration range of only nM to µM, while NMR typically requires the analyte to be in the mM range (>1000 times more concentrated!). In this blog, we will demonstrate why NMR is considerably less sensitive than UV-Vis. We have chosen UV-Vis for this comparison as it is widely recognized as one of the most sensitive spectroscopic techniques.
