  • Patent number: 11333639
    Abstract: Systems, apparatuses, kits, and methods for purification and analysis of analytes having a broad range of hydrophobicities by liquid chromatography-mass spectrometry (LC-MS). Using one set of liquid chromatography columns, one set of mobile phase buffers, and, optionally, a single ionization method (e.g., electrospray ionization), a wide range of analytes can be purified and analyzed on a liquid chromatography-mass spectrometry (LC-MS) system. LC-MS purification and analysis of analytes having a broad range of partition coefficients is accomplished by selecting LC run parameters and MS system parameters that are particular to different classes of analytes without having to make column or buffer changes or any other hardware configuration changes to the LC-MS system.

  • Patent number: 9063159
    Abstract: Systems, kits, and methods for quantitation of metabolites of vitamin D by liquid chromatography-mass spectrometry (LC-MS). The systems, kits, and methods described herein stabilize and/or promote the formation of the protonated molecular ion ([M+H]+) for the vitamin D metabolites in the ionization source (e.g., electrospray ionization (“ESI”)). Formation of the molecular ion does not involve loss of a water molecule from the parent molecule. Subsequent fragmentation of the [M+H]+ ion yields product ions that are specific to each molecular ion. The systems, kits, and methods described herein provide for no compromise in specificity and provide for a significant increase in sensitivity relative to previously described methods.

  • Patent number: 7767463
    Abstract: A method and system of screening or selecting a mobile phase eluent for a chromatography column is provided. A sample for chromatographic analysis or purification is combined with a solvent and passed through a membrane. A pressure measurement is taken of the sample/solvent combination in the system prior to the membrane. The pressure measurement may be compared to a second pressure and an appropriate solvent may be selected based on the relationship between the first measured pressure and the second pressure.

  • Patent number: 6969400
    Abstract: Provided are crosslinked polymer compositions that include a first synthetic polymer containing multiple nucleophilic groups covalently bound to a second synthetic polymer containing multiple electrophilic groups. The first synthetic polymer is preferably a synthetic polypeptide or a polyethylene glycol that has been modified to contain multiple nucleophilic groups, such as primary amino (—NH2) or thiol (—SH) groups. The second synthetic polymer may be a hydrophilic or hydrophobic synthetic polymer, which contains or has been derivatized to contain, two or more electrophilic groups, such as succinimidyl groups. The compositions may further include other components, such as naturally occurring polysaccharides or proteins (such as glycosaminoglycans or collagen) and/or biologically active agents.
