Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes Portable / Miniature, visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available.

  • Solvent Recovery Using a Near-Infrared ChemView(R) Photometer
    and import them into Microsoft(R) Excel(R). Use our OutlierDetectTM Excel(R) add-in to determine the MLR coefficients and perform the outlier analysis. 3036_SolventRecovery Application Note --. Solvent Recovery Using a Near-Infrared ChemView® Photometer. Purpose: To measure the concentrations of ethyl
  • Continuous Fuel Identification for Pipelines with a ClearViewTM Photometer
    Reliable, affordable, real-time identification of petroleum products flowing in pipelines to minimize waste and assist in transitions. Experimental: ClearViewTM fiber optic filter photometer. Fiber optic flow probe with 1 cm optical path. Pair of 2 meter low-0H fiber optic cables. Near-infrared
  • Ethylene: Diethylene Glycols On-Line Monitoring with a ClearViewTM Photometer
    To replace a gas chromatograph (GC) by continuously measuring the amount of ethylene glycol in diethylene glycol using a near infrared (NIR) ClearViewTM fiber optic filter photometer. Background: It is not obvious, even to many NIR practitioners, that NIR can make more subtle distinctions among
  • Water in TiO2-Loaded Polymer with Reflectance NIR in a ChemView(R) Photometer
    Purpose: To determine water content in a white polymer liquid containing TiO2 using a near-infrared (NIR) Chem-View(R) photometer and fiber optic reflectance probe. Approach: Samples were mixed with TiO2 and water was added by weight. In order to determine the best wavelengths for our ChemView(R
  • Water Analysis in an Alcohol-Brine Solution with a ChemView(R) Photometer
    . Near-infrared (NIR) spectra are rich in chemical information. These spectra are complex with overlapping peaks from water and alcohols, as shown at middle right. A careful analysis of the spectra reveals that a single wavelength at 1820 nm measures water with minimal interferences from methanol
  • Water in Acetic Acid On-Line Monitoring with a ClearViewTM Photometer
    Purpose: To determine water content in acetic acid with sample temperature correction. Approach: The PS¬-2 NIR diode array spectrometer was used to measure the near-infrared spectra of 0-15% water in acetic acid at various temperatures in a 5 mm cuvette in the HeaterCellTM fiber optic accessory
  • Continuous, On-Line NIR Analysis of Process Gasses
    Near infrared (NIR) is not commonly associated with on-line analysis of process gasses in comparison to infrared (IR) and the ubiquitous, but maintenance-intensive gas chromatograph (GC). The purpose of this application note is to demonstrate not only the specificity, but also the quantitative
  • Process Turbidity Analyzers
    spectrophotometer. Process scale absorption based photometers, are set at a fixed wavelength or bandwidth, rather than having the ability to select the wavelength. Three-dimensional solids will exhibit absorbance at virtually all frequencies of light, however at short wavelength Infrared or Near Infrared (NIR
