Patent

CA 2751330

Provided are monodisperse synthetic dendrimer calibrants for mass spectrometry. The calibrants are distinguished by their relative ease and rapidity of synthesis, comparatively low cost, long shelf life, high purity, and amenability to batch synthesis as mixtures. The latter characteristic enables parallel preparation of higher molecular weight compounds displaying useful distributions of discrete molecular weights, thereby providing multi-point mass spectrometry calibration standards. Methods of making and using said calibrants are also provided.

L'invention concerne des étalons de type dendrimères synthétiques monodispersés pour spectroscopie de masse. Les étalons sont relativement simples et rapides à synthétiser, comparativement peu coûteux, très purs, peuvent être conservés longtemps et synthétisés en lot sous forme de mélanges. Cette dernière caractéristique permet la préparation parallèle de composés de poids moléculaire plus élevé présentant des répartitions utiles de poids moléculaires discrets, ce qui permet d'obtenir des étalons multipoints pour spectroscopie de masse. Des procédés de préparation et d'utilisation desdits étalons sont également décrits.
