  • Patent number: 9341604
    Abstract: The present disclosure provides adaptive methods for gas chromatography analysis of a gas sample comprising one or more target analytes (such as a micro-gas chromatography) and adaptive gas chromatography devices for carrying out such analytical methods. Broadly, the system can regulate flow into a downstream chromatographic column by detecting one or more upstream conditions. For example, one adaptive chromatography device comprises a first column, a modulator component, and a second column. A first detector or sensor detects the presence of target analytes upstream from the second column, while a second detector detects the presence of target analytes eluted from the second column. The modulator component assembly is responsive to an output generated by the first detector and adaptively regulates fluid flow into the second column. Such adaptive chromatography (micro-GC) systems have higher separation speed, better analyte identification capability, and far greater energy savings.

  • Patent number: 9285306
    Abstract: An optical absorption gas sensor has an LED light source and a photodiode light detector, a temperature measuring device for measuring the LED temperature and a temperature measuring device for measuring the photodiode temperature. The sensor is calibrated by measuring the response of photodiode current at zero analyte gas concentration and at a reference analyte gas concentration. From these measurement, calibration data taking into account the effect of photodiode temperature on the sensitivity of the photodiode and, independently, the effect of changes in the spectrum of light output by the LED on the light detected by the photodiode with LED temperature can be obtained. Calibration data is written to memory in the gas sensor and in operation of the gas sensor, the output is compensated for both LED and photodiode temperature. The LED and photodiode can therefore be relatively far apart and operate at significantly different temperatures allowing greater freedom of optical pathway design.

  • Patent number: 8956567
    Abstract: A control system for optimizing a chemical loop system includes one or more sensors for measuring one or more parameters in a chemical loop. The sensors are disposed on or in a conduit positioned in the chemical loop. The sensors generate one or more data signals representative of an amount of solids in the conduit. The control system includes a data acquisition system in communication with the sensors and a controller in communication with the data acquisition system. The data acquisition system receives the data signals and the controller generates the control signals. The controller is in communication with one or more valves positioned in the chemical loop. The valves are configured to regulate a flow of the solids through the chemical loop.

  • Publication number: 20150032383
    Abstract: This invention relates to a system for and a method of filtering at least a part of gas chromatography-mass spectrometry data, the method comprising: providing gas chromatography-mass spectrometry data (301) for a gas mixture comprising data representing one or more gas chromatography elution peaks obtained for at least one sample, and filtering the gas chromatography-mass spectrometry data (301) to reduce the amount of data, wherein the filtering comprises taking into account predetermined data representing one or more elution peaks previously determined to be false positives (305) and/or predetermined data representing one or elution peaks previously determined to be true positives (304). In this way, unreliable elution peaks are removed in an expedient manner reducing the amount of data e.g. used for a later alignment process speeding up the processing time and also improving the data quality.

  • Patent number: 8942944
    Abstract: An oxygen sensing system including an oxygen sensor, a microprocessor and one or more additional sensors for sensing parameters associated with the environment or with the oxygen sensor, accounts for one or more sensed conditions when calculating oxygen levels. The one or more sensors may sense conditions associated with environmental effects or effects of use that may cause the oxygen sensor to degrade over usage or over time. A baseline amplification and measurement circuit coupled to the oxygen sensor may enable the sensor to operate less frequently or for shorter periods of time, thereby increasing the life span, calibration hold time of the sensor, and reducing power requirements.

  • Publication number: 20150025813
    Abstract: Systems and methods are provided to perform sequential windowed acquisition of mass spectrometry data. A mass range and a mass window width parameter are received for a sample. A plurality of ions from the sample that are within the mass range are collected in an ion trap of a mass spectrometer. Two or more mass adjacent or overlapping windows are calculated to span the mass range using the mass window width parameter. Ions within each mass window are ejected from the ion trap. A mass spectrum is then detected from the ejected ions of the each mass window with a mass analyzer of the mass spectrometer, producing a collection of mass spectra for the mass range. The two or more mass windows can all have the same width, can all have different widths, or can have at least two mass windows with different widths.

  • Publication number: 20140335905
    Abstract: The portable breathalyzer accessory combines a blood alcohol content measuring tool with a mobile device to measure, store, and send the blood alcohol content of the user. The portable breathalyzer device attaches to a mobile device, wired or wirelessly, to display the blood alcohol content of the user, which is measured through the portable breathalyzer attachment. The blood alcohol content is displayed as a percentage on the mobile device through the corresponding software application. The software application shows the user their blood alcohol content in comparison with the local blood alcohol content limit, which is found by determining the user's location through the GPS technology of the mobile device.

  • Publication number: 20140336952
    Abstract: Sensing particular gases in a mixture uses precise modulated heating. Sensor relative responses are compared at different temperatures and compared with known relative responses to identify gases and concentrations. Heater current sensors provide feedback control and microprocessor inputs. A processor controls complex impedances and varied frequencies in the sensors. Sensor responses at varied complex impedances and at varied frequencies are compared with known responses at those impedances and frequencies to determine existence and concentration of particular gases. Heater and sensor buses are separate or combined.

  • Patent number: 8886467
    Abstract: The chemical distance between fingerprints of fluid samples from a reservoir can be determined using statistical analyses. Upon performing chromatographic analyses on fluid samples from the reservoir, certain peak height values from the chromatograms are selected, and various peak height ratios are formed using the selected peak height values. An experimental distribution of the differences between the peak height ratios is produced using two chromatograms from one of the fluid samples and a theoretical distribution of the differences of the peak height ratios are produced assuming the two chromatograms are from the one of the fluid samples. An uncertainty model of the peak height values is optimized and the parameters of the optimized uncertainty model are used to modify the theoretical distribution. The interquartile ranges of the experimental distribution and the modified theoretical distribution are determined and the chemical distance between the samples is determined using the interquartile ranges.

  • Patent number: 8880355
    Abstract: According to one embodiment, an emission factor calculating apparatus includes a receiving unit, a received electricity (i.e., electric power) measuring unit, a generated electricity measuring unit, and an emission factor calculating unit. The receiving unit receives an emission factor of a higher-level system at first regular intervals. The received electricity measuring unit measures, as a received electricity, electricity received from the higher-level system and accumulated. The generated electricity measuring unit measures electricity generated with zero emission in a target system. The emission factor calculating unit calculates a substantial emission factor of the target system at regular intervals (i.e., at a fixed interval), based on a ratio between the received electricity and the measured electricity generated, and the emission factor of the higher-level system. The emission factor calculating unit informs a load or a lower-level system of the substantial emission factor.
