Abstract: The present invention is enclosed in the area of machine learning, in particular machine learning for the analysis of High or Super-resolution spectroscopic data, which typically comprises analysis of highly complex samples/mixtures of substances and/or data with low resolution, for instance Laser-Induced Breakdown Spectroscopy (LIBS). It is an object of the present invention a method of computational self-learning for characterization of one or more constituents in a sample, from electromagnetic spectral information of such sample, which changes the paradigm associated with prior art methods, by using only sub-optical spectral information, i.e., obtaining the resolution of the spectral information and thereby be able to extract spectral lines—thus determining a spectral line position—from such spectral information, hence avoiding all the uncertainty associated with pixel based methods. It is also an object of the present invention a computational apparatus configured to implement such method.

Abstract: The present invention relates to a process, reactor and system to produce self-standing two-dimensional nanostructures, using a microwave-excited plasma environment. The process is based on injecting, into a reactor, a mixture of gases and precursors in stream regime. The stream is subjected to a surface wave electric field, excited by the use of microwave power which is introduced into a field applicator, generating high energy density plasmas, that break the precursors into its atomic and/or molecular constituents. The system comprises a plasma reactor with a surface wave launching zone, a transient zone with a progressively increasing cross-sectional area, and a nucleation zone. The plasma reactor together with an infrared radiation source provides a controlled adjustment of the spatial gradients, of the temperature and the gas stream velocity.

Abstract: A liquid chromatography system includes an autosampler with an injector valve by which a sample at low pressure within a sample loop is introduced into a high-pressure solvent mixture stream. A solvent delivery system includes a pump in fluidic communication with the injector valve of the autosampler to deliver the solvent mixture stream thereto. The solvent delivery system further comprises a processor that calculates a number of strokes of the pump needed to deliver the solvent mixture stream to the injector valve of the autosampler. The processor counts strokes of the pump during delivery of the solvent mixture stream. In response to a stroke count equaling the calculated number of strokes, the processor signals the autosampler to switch the injector valve to introduce the sample to the solvent mixture stream during a pump transfer period within which the pump performs pressure control to compensate for a drop in pressure.

Abstract: A liquid chromatography system includes an autosampler that prepares a sample for introduction to a solvent stream and a solvent delivery system that delivers a solvent stream to the autosampler. Delivery of the solvent stream occurs in parallel with the autosampler's pre-injection operations. The autosampler starts pre-injection operations to make the sample ready for injection into the mixture stream, and the solvent delivery system starts delivery of a solvent stream to the autosampler. The start of the solvent stream delivery is coordinated with the start of the pre-injection operations such that the solvent stream arrives at the autosampler approximately coincident with when the autosampler completes the pre-injection operations, making the sample ready for injection.

Abstract: Described is an apparatus for reducing a temperature variation of a liquid chromatography sample. A tray drive using at least one of linear or rotational motion moves a sample tray along a path inside a sample compartment of the liquid chromatography system. A control module coordinates the movement of the sample tray by the tray drive and the movement of a sample needle by a needle drive so that any sample in the sample tray can be injected into the mobile phase of the system during a sample load operation. The tray drive is also used to move the sample tray along the path during a temperature averaging period when no loading occurs. Differences in sample temperatures due to variations in the air temperature at different locations inside the sample compartment are reduced, leading to more accurate and repeatable chromatographic measurement results.

Abstract: Systems, devices, and methods to mitigate the pressure disturbance associated with the injection of low-pressure analyte samples into a high-pressure HPLC fluid stream, to enhance chromatographic performance related to retention time and reproducibility. The preferred embodiment coordinates the injection run with active pressure control of a binary solvent delivery system to virtually eliminate the customary pressure drop when the low-pressure loop is brought on line. An additional benefit that enhances reproducibility is accomplished by forcing a consistent timing relationship between the injection run, the mechanical position of the delivery pump pistons, and the start and subsequent gradient delivery.
