Abstract: The present invention provides methods for high throughput analysis of analytes in complex mixtures for unresolved chromatographic peaks including specific embodiment for summing intensities for each mass transition of interest over a selected chromatographic peak (50) to generate a signal corresponding to total intensity for each transition (55, 60). The intensities are deconvoluted into intensities of individual analytes (65, 70), based on branching ratios acquired from authentic standards, and a comparison to calibration curve is performed to obtain a quantitative concentration measurement of a particular analyte in a sample.

Abstract: A door security device (1) consisting of a substantially trapezoidal plate (4) residing parallel to the plane of the door and an integrally formed lip (6) which is permanently affixed to door frame structural member (2). A door strike reinforcement tube (10) extends perpendicularly from plate (4) and is aligned with door lock striker (25) such that any force applied to the door (15) is resisted by the entire plate reinforcing device. A plurality of strike plate reinforcement extensions (10a) may also be used with multiple lock mechanisms.
