摘要： A method for analyzing a gas sample is described. The method comprises providing a gas sample, increasing pressure applied to the gas sample to compress the sample to a smaller volume and provide a pneumatically focused gas sample, and analyzing the pneumatically focused gas sample using any of a variety of analytical techniques. Pneumatic Focusing generally means increasing the pressure of the sample, column or cell to a pressure of from about 100 psi to about 15,000 psi, more typically from about 200 psi to about 2,000 psi. Examples including gas chromatography and absorption spectroscopy are illustrated herein. Numerous other examples could be given. The method is well suited for analyzing gaseous samples, such as ambient air samples, both continuously, and remotely, using computer control. Continuously sampling ambient air provides a method for real-time monitoring of air quality. Continuous monitoring allows for pollutant exposure and allows for the identification of emission sources. The method is also well suited for analysis of breath exhalations from respiring organisms useful in metabolic studies or disease diagnosis.

摘要： A method, apparatus, and article of manufacture for enhanced integration of signals, such as those generated by chromatographs. In one embodiment an approximate baseline used for integration of a signal is improved to reduce error. Alternate embodiments filter drift, noise, or both from a signal prior to integration or simulated distillation. The signals are processed according to a computer program stored in a memory. The methods include steps for subtracting an approximate baseline from the signal, defining a noise band in the resulting difference, and forming a composite baseline by substituting signal data for baseline data wherever the difference does not exceed the threshold, thus leaving the parts of the approximate baseline that correspond to signal peaks unchanged.

摘要： Biological samples are analyzed for benzodiazepines in a single isocratic analysis using a chromatographic column system containing an immobilized enzyme reactor which cleaves glucuronic acid-conjugated benzodiazepines, an anion exchange column, a hydrophobic cation exchange column and a reverse-phase analytical column. Preferred methods of performing the analysis further involve the use of a hydrophobic cation exchange precolumn prior to the anion exchange column. The system readily lends itself to automation, automatic periodic sampling and benzodiazepine identification and quantification. The system is particularly well adapted to the determination and identification of benzodiazepines in urine samples.

摘要： A method for improving the limit of detection for a data set in which experimental noise is uncorrelated along a given abscissa and an analytical signal is correlated to the abscissa, the steps comprising collecting the data set, converting the data set into a data signal including an analytical portion and the experimental noise portion, designating and adjusting a baseline of the data signal to center the experimental noise numerically about a zero reference, and integrating the data signal preserving the corresponding information for each point of the data signal. The steps of the method produce an enhanced integrated data signal which improves the limit of detection of the data signal.
