In the case where a plurality of analysis data files which respectively contain analysis results and data-analyzing process results for a plurality of samples should be managed as one lot, a portion of the information contained in those analysis data files is extracted and compiled into a final result record report file. This file is registered in a database. A supervisor views the final result record report on a client terminal, evaluates the validity of the analysis result and other contents for each sample, and performs a predetermined operation to execute the signature of approval or other evaluations. Signature information, including the signer's name, date and time of the signature, etc., is recorded for the final result record report file. The same signature information is also recorded for each of the analysis data files located by referring to link information.

Components resolved in time by a separator accumulate in a sample cell and are analyzed by electromagnetic radiation-based spectroscopic techniques. The sample cell can be configured for multiple path absorption and can be heated. The separator can be a gas chromatograph or another suitable device, for example a distillation-based separator. The method and system described herein can include other mechanical elements, controls, procedures for handling background and sample data, protocols for species identification and/or quantification, automation, computer interfaces, algorithms, software or other features.

Disclosed herein are scientific instrument support systems, as well as related methods, computing devices, and computer-readable media. For example, in some embodiments, a scientific instrument support apparatus includes a first logic to obtain chromatographic data sets from a chromatographic system; a second logic to perform a first analysis of the one or more chromatographic data sets to generate a first result perform a second analysis of the one or more chromatographic data sets to generate a second result; and a third logic to identify differences between the first result and the second result; provide a user interface configured to indicate the data sets where the second result differs from the first result; and display one or more chromatograms representative of the indicated data sets and visually identifying features on the chromatograms where the differences occur.

A model for locating a peak portion in a chromatogram or similar waveform is trained by machine learning using multiple sets of partial waveforms prepared by dividing each reference waveform having a known peak position. An analysis-target waveform is divided into partial waveforms, and whether or not a partial waveform is a peak portion is determined for each partial waveform by the trained model, to estimate different kinds of regions in the analysis-target waveform, including an overlap-peak region. For an overlap peak within a region estimated to be an overlap-peak region, whether or not that peak is a multimodal peak originating from one component is determined, using at least the height of a peak in the overlap peak, the depth of the trough between two neighboring peaks, or the horizontal width of the portion between the bottom of the trough and the top of one of the neighboring peaks.

A method for quantifying a plurality of compounds with the same chromophore using a single standard is provided. In the method, the standard curve of the standard is plotted, the calculation curve of the compound to be tested with the same chromophore as the standard is derived, and the quantitative determination of the compound to be tested is realized according to the calculation curve. The method requires few standards, leads to accurate determination results, and also saves time and costs in a series of methodological investigations such as establishment of individual standard curve for each component, thereby improving the efficiency of method development.

A conductive composition may include a conductive polymer (A) having an acidic group, and a basic compound (B), wherein: an X/Y area ratio is 0.046 or less, which is a ratio an area (X) of a region corresponding to molecular weight (M) ranging from 300 to 3300, relative to an area (Y) of an entire region ascribed to the conductive polymer (A); or a ZS/ZR ratio is 20 or less. ZS is a maximum fluorescent intensity value in a range of 320 to 420 nm when a fluorescence spectrum is measured at 230 nm excitation wavelength in a solution obtained by diluting the conductive composition with water to adjust the conductive polymer (A) solids content to 0.6 wt. %.
