摘要： The present disclosure relates generally to systems for accurate quantitation of naphthenic acids in liquid samples. The system allows efficient identification as well as quantitation of NA species based on carbon number and ring structure, but requires no chemical modification or extraction of the sample allowing a rapid throughput. Reverse phase liquid chromatographic separation of the sample minimizes (or eliminates) matrix suppression effects to allow detection of all NAs present in various samples by mass spectroscopy with superior detection thresholds that are as much as 350-fold lower than conventional systems.

摘要： A two-dimensional fluorescent densitometry for measuring a specimen plate having a specimen spot such as phospholipide two-dimensionally developed and fluorescent-labelled on a TLC plate. The densitometer comprises an excitation optical system for scanning a measuring plate with an excitation light beam, a fluorescence detection system for detecting a fluorescence from the measuring plate, a correction table for storing fluorescent data together with positional information in a scanning direction on the measuring plate, and an arithmetic section for dividing fluorescence detection data by fluorescent data at the same position in the scanning direction on the measuring plate stored in the correction table.

摘要： In measuring the signal peaks caused by unknown samples in, for example, the detector outputs of gas chromatographs, the peak signals are identified as to the unknown sample components by comparing their time of occurrence (the retention times of the sample components) to the times of occurrence of known components from a previously run known sample. The peak signals are then integrated to find their areas and each peak area is multiplied by a different stored calibration factor, in accordance with (the reciprocal of) the sensitivity of the detector to each particular sample component. Rather than determining whether the unknown sample components have a retention time within a tolerance range about the respective retention times of previously run known sample components as done in the past, the present technique uses the criterion of whether any part of the unknown peak has the same time of occurrence as the center of the known sample peak. In this manner, the effective tolerance range of the respective retention times is determined by the width of the unknown sample peak, so that the tolerance range is automatically compensated in accordance with the chromatographic operating conditions and inherent characteristics of the sample component, which affect the broadening of peaks.
