  • Title: Design and performance of a high pressure insert for use in a standard magic angle spinning NMR probe.
    Author: Deuchande T, Breton O, Haedelt J, Hughes E.
    Journal: J Magn Reson; 2006 Dec; 183(2):178-82. PubMed ID: 16962344.
    Abstract:
    In this paper we describe the construction and performance of high pressure magic angle inserts made from the polymer PEEK. The inserts were designed to fit inside standard commercial 7 mm magic angle spinning rotors and spin at the maximum frequency of the probe. The sample volume of the inserts was 100 microL. A gas loading chamber that operates at room temperature is described. The performance of the inserts is discussed for a number of gases in terms of resolution as a function of spinning speed and leakage of the gas due to permeation through the polymer. Finally, some preliminary results are shown in relation to complex food materials.
