  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • Demonstration of an Ethane Spectrometer for Methane Source Identification

    ABSTRACT: Methane is an important greenhouse gas and tropospheric ozone precursor. Simultaneous observation of ethane with methane can help identify specific methane source types. Aerodyne Ethane-Mini spectrometers, employing recently available mid-infrared distributed feedback tunable diode lasers (DFB-TDL), provide 1 s ethane measurements with sub-ppb precision. In this work, an Ethane-Mini ...

  • Resolution in life and mass spectrometers? It really depends…

    “How few there are who have courage enough to own their faults, or resolution enough to mend them.” Benjamin Franklin As I sat one morning before work staring into my green tea leaves at the bottom of my cup and reflecting on my resolutions achieved and resolutions that evaded me in 2015, I resolved to make 2016 a better year. The ‘missed’ resolutions ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • InfraSpec VFA-IR Spectrometer for Biodiesel Blend Measurements

    Synopsis: Simple, yet powerful, filter-based IR spectrometers are ideal for compliance to the new ASTM 7861 test method for accurately measuring biodiesel blend ratios. The Wilks InfraSpec analyzer was the instrument used to develop and validate this method and thus is the industry standard for field measurement of FAME (Fatty Acid Methyl Ester) blend percentages. ...

  • Determination of oil and grease in water with a mid-infrared spectrometer

    The concentration of dispersed oil and grease (OG) is an important parameter for water quality and safety. OG in water can cause surface films and shoreline deposits leading to environmental degradation, and can induce human health risks when discharged in surface or ground waters. Additionally, OG may interfere with aerobic and anaerobic biological processes and lead to decreased wastewater ...

  • Prediction of intact nectarine quality using a Vis/NIR portable spectrometer

    A commercial visible-near infrared spectrometer was tested for intact nectarine quality prediction using partial least squares calibrations. Soluble solids content, firmness, fruit weight and colour index were analysed in each fruit. External validation carried out indicated good predictive performance, particularly for soluble solids content and fruit firmness. These parameters are of key ...
