20140242709 | RAPID FLUORESCENCE TAGGING OF GLYCANS AND OTHER BIOMOLECULES WITH ENHANCED MS SIGNALS - Reagents comprising MS active, fluorescent molecules with an activated functionality for reaction with amines useful in tagging biomolecules such as N-glycans and uses thereof are taught and described. | 08-28-2014 |
20140319057 | CHROMATOGRAPHIC MATERIALS FOR THE SEPARATION OF UNSATURATED MOLECULES - The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group. | 10-30-2014 |

20140366656 | SOLID PHASE EXTRACTION DEVICE FOR DRIED SAMPLE CARDS - Described is a device for solid phase extraction of a dried sample of a biological fluid. The device includes a support structure such as a plate or support block that has a first side to receive a dried sample card. The support structure also has a second side that is opposite the first side and a number of apertures that extend between the first and second sides. The device also includes a plurality of wells each containing a sample preparation material and having an inlet end that communicates with a respective aperture at the second side of the support structure. Each dried sample on the dried sample card is aligned with one of the apertures. Extraction samples in each well pass through the sample preparation material, such as a chromatographic sorbent, in the well to remove one or more constituents of the extraction sample. | 12-18-2014 |
