摘要： In the case where a given mass range is repeatedly scanned to sequentially create mass spectra and create a mass chromatogram or the like, when a number of data, which are arranged on the mass axis and constitute a mass profile of the given mass range, are collected for a predetermined number of the alignment (S1 and S2), a two-dimensional filtering process is performed by correcting the target data, for each data aligned in the mass axis direction, using the data contiguous before and after in the mass axis direction and the data contiguous before and after in the time axis direction (S3). For the mass profile constituted of the data thus processed, a peak detection is performed (S4) and the peak's mass number is determined to create a mass spectrum (S5). Consequently, the mass numbers' fluctuation in the mass spectrum is moderated, the mass resolution is increased, and the accuracy of the mass chromatogram is also increased.

摘要： Signals obtained in High Performance Liquid Chromatography (HPLC) are notoriously noisy. The signal can be improved by increasing the path length of the light passing through the sample, but increased path length also invites greater refraction and reflection of that light. A novel approach is to utilize a number of photocell sensors lined up along a capillary through which the solution passes. Through careful measurement and calculation, a signal for a single fluid particle can be produced by all the photocell sensors. By incorporating an appropriate delay between each signal, to take into account the finite speed of the fluid, the resulting plurality of noisy signals can be summed or statistically correlated. The signal, containing the important information about the fluid, will increase with the number of photocells used, while the noise increases by the square root of the number of photocells used. The signal to noise ratio, then, increases as the square of the number of photocells used. In this way, the effective path length is increased without including any moving parts.

摘要： A high dynamic range apparatus for separation and detection of polynucleotide fragments has a housing adapted to receive an electrophoresis gel holder containing an electrophoresis gel loaded with fluorophore-labeled samples; one or more laser diodes for providing radiation of a frequency suitable for excitation of the fluorophore which irradiates a an array of excitation/detection sites on the electrophoresis gel; an array of detectors aligned with the excitation/detection sites for collecting fluorescent emissions; and one or more components for increasing the dynamic range of the instrument by at least an order of magnitude. These components, which can be used individually or in combination include detectors that are connected to a signal processing system that modulates the period of signal integration employed so that large signals are totaled at short time intervals and smaller signals are totaled at longer time intervals; the use of a beam splitter to produces a high intensity beam of emitted light and a low intensity beam of emitted light from each excitation/detection site; and a device for modulating the intensity of the excitation beam can be used to improve the dynamic range of the instrument.

摘要： A waveform-analyzing system, particularly for use with chromatographs, wherein the waveform is integrated between selected characteristic points thereof, and selected peaks of the waveform are used as recycling zero time markers which act to restart a timing device programmed to stop before each successive one of said selected peaks instead of operating relative to a continuously running time scale defined by a single point at the beginning of the waveform.

摘要： A method of analyzing data from a mass spectrometer for a data dependent acquisition is described. In an embodiment of this method, mass spectral scans are taken of a sample eluted from a liquid chromatography column. An extracted ion chromatogram (XIC) is then created for each m/z data point of the mass spectral scans and the XIC for each m/z data point are correlated to a model function, such as a monotonically increasing function, or the first half of a gaussian function, to obtain a XIC correlation value. A weighting function is then applied to the XIC correlation value to obtain a current weighted intensity. The current weighted intensity for each m/z point is used to reconstruct a weighted mass spectrum, which is then used to make a real-time decision for the data dependent acquisition. In an embodiment, the data dependent acquisition is the performance of tandem mass spectrometry. Embodiments of the invention also describe a sample processing apparatus for the data dependent acquisition and a computer readable medium that provides instructions to the sample processing apparatus to perform the method described above.

摘要： An improved method and apparatus for identifying peaks and for determining the boundaries of those peaks, and boundaries of multiple peaks and shoulders within chromatograms. The method and apparatus effects real time identification and determination of the boundaries of these peaks for the purpose of fraction collection. The method and apparatus determines the boundary of a peak within a detector response profile that comprises data points plotted graphically on an X and Y-axis wherein the X-axis represents a first variable and the Y-axis represents a second variable, each variable having a value. The plot at each of the data points has a slope. Data points having a slope which deviates from a consistent value define a peak, and data points having a slope with a consistent value define a baseline.

摘要： Deconvolution of up to three overlapping chromatographic peaks is provided in which pure spectral components are extrapolated from a Euclidean-normalized expression of chromatographic data in the space of the three principal factors. A coordinate transformation to planar coordinates after expansion in factor space and before extrapolation yields the simplicity of linear extrapolation in combination with the inherent accuracy of Euclidean, as opposed to standard, normalization. The estimation of the pure component spectra permits the constructions of a concentration matrix. Improved estimates and an error bound are provided by applying assumptions of non-negativity and limited deviation from the means to the concentration matrix.
