Services
   Test Methods       
   Your choices are...         
   Auger Spectroscopy (AES)       Auger electron spectroscopy (AES) is an analytical technique that examines material surfaces for low-energy, valance electrons. These low-energy, secondary electrons are used to identify elemental composition. 
   Atomic Absorption Spectroscopy (AA)       Atomic absorption (AA) spectrometers use light absorption to measure the concentration of gas-phase atoms. An analyte, usually a solid or liquid, is vaporized in a flame or in a graphite furnace with a temperature of 1000° - 1200° K. Atoms absorb ultraviolet or visible light and achieve higher energy levels. Absorption amounts determine the analyte concentration. 
   Chemical Extraction       Chemical extraction services remove elements through a reaction with an extractant solution. 
   Chromatography (GC, HPLC, etc.)       Chromatography separates compounds by their distribution between two phases and produced chromatograms. Examples include ion chromatography, high performance liquid chromatography (HPLC), and gas chromatography (GC). 
   Diffraction (X-ray, Electron, etc.)       Diffraction instruments measure crystal structure, grain size, texture, and/or residual stress of materials and compounds. 
   Inductively Coupled Plasma (ICP / LA-ICP)       Inductively coupled plasma (ICP) is a very high temperature (7000° - 8000° K) excitation source that efficiently desolvates, vaporizes, excites, and ionizes atoms. Molecular interferences are greatly reduced with this excitation source, but are not completely eliminated. ICP sources are used to excite atoms for atomic emission spectroscopy and to ionize atoms for mass spectrometry.  Laser ablation (LA) is used in conjunction with ICP techniques to analyze solid samples. A laser is used to extract a minute volume from the surface of the solid sample on the order of 10 microns in diameter. 
   Infrared Spectroscopy (FTIR, etc.)       Infrared (IR) spectroscopy measures the wavelength and intensity of the absorption of infrared light by a sample. Mid-infrared light (2.5 - 50 µm, 4000 - 200 cm) is energetic enough to excite molecular vibrations to higher energy levels. The wavelength of IR absorption bands is characteristic of specific types of chemical bonds. IR spectroscopy finds its greatest use in the identification of organic and organometallic molecules. 
   Isotopic Analysis       Isotopic analysis can include the identification and quantification of stable or unstable isotopes within a sample. 
   Mass Spectroscopy (RGA, etc.)       Mass spectrometers separate ions by their mass-to-charge (m/z) ratios. They are used to identify compounds by the mass of one or more elements in the compound. They are also used to determine the isotopic composition of one or more elements in a compound. 
   Microscopy / Fiber Examination       Microscopy and metallography study the structure and composition of materials by using low to high powered magnification with optical and electron microscopes, spectrometry, diffraction, X-ray, and other analytical techniques. 
   Optical Emission Spectroscopy       Optical emission spectroscopy may include spark, DC arc, or photo emission. 
   Particle Size / Sieve Analysis       Particle testing services determine particle size or particle count.  These services may include sieving, dynamic light scattering, electrozone sensing, laser diffraction, low angle light scattering (LALLS), microscopy, or sedimentation. 
   Scanning Electron Microscopy       Scanning electron microscopy (SEM) services may include failure analysis, material analysis, and the elemental analysis (EDS) of extremely small particles. SEMs are electron microscopes in which the image is formed by synchronizing a detector with a focused electron beam that scans the object. The intensity of the image-forming beam is proportional to the back scattered or secondary emission of the specimen where the probe strikes. The magnification is controlled by the length or area scanned. 
   SDWA       Companies can analyze and characterize water samples for quality using Source Drinking Water Analysis (SDWA) methods. 
   TCLP       Toxic Characteristic Leaching Procedure (TCLP) simulates sanitary landfill containment leaching in waste samples. It was established by the EPA and is also known as EPA SW-846 analytical Method 1311. 
   Trace Analysis (ppm, ppb, ppq)       Trace analysis can detect very low levels of metals, elements, or other chemicals within a sample. The trace level can represent co-contamination or be intentionally added as part of the process. Trace levels are measured in parts per million (ppm), parts per billion (ppb), parts per trillion (ppt), or parts per quadrillion (ppq).  
   UV / Vis Spectroscopy       UV / Vis spectroscopy is used to determine the bulk concentration of a sample by analyzing transmitted light through the sample. Absorption patterns and other optical properties are used to determine the bulk composition. 
   Wet Chemical Analysis       Wet chemical analysis excludes all techniques that use instrumentation for quantitative analysis. It plays on important role in many other analytical applications including coating identification and wear metal identification. 
   X-ray Fluorescence (XRF)       X-ray fluorescence spectrometers (XRF) use a spectroscopic technique (commonly used with solids) in which X-rays excite a sample and generate secondary X-rays. The X-rays broadcast into the sample eject inner-shell electrons. Outer-shell electrons take the place of the ejected electrons and emit photons in the process. The wavelength of the photons depends on the energy difference between the outer-shell and inner-shell electron orbitals. The amount of X-ray fluorescence is very sample dependent and quantitative analysis requires calibration with standards that are similar to the sample matrix.
