Application Notes: General
Using the Full Spectrum for Raman: From UV to NIR
The "inelastic scattering of light," or Raman effect, was observed in practice for the first time in 1928 by C.V. Raman for which he was awarded the Nobel Prize in 1930.
Determination of Sodium Lauryl Sulfate and Sodium Laureth Sulfate in Commercial Body Care Products
September 1st 2014A method for quantifying the percent sulfate associated with sodium lauryl sulfate (also referred to as sodium dodecyl sulfate) and sodium laureth sulfate (also referred to as sodium lauryl ether sulfate) found in commonly used commercial body care products using FT-IR attenuated total reflectance (ATR) spectroscopy is outlined.
Lanthanide Series Investigations with TSI LIBS Desktop Analyzer
September 1st 2014The lanthanide series is a series of metallic elements, with atomic numbers 58 through 71, which are - in order of increasing atomic number - cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium.
Characterization of Diesel Fuel Using a Modular Raman System
February 1st 2014Raman spectroscopy is an excellent technique for the identification and characterization of fuels. With no requirement for sample preparation and the power to identify and quantify materials, Raman has many uses across a range of industries.
Single Reaction Chamber Microwave Digestion for Specialty Chemicals
February 1st 2013Single reaction chamber microwave digestion enables a chemist to digest up to 15 different specialty chemical samples simultaneously at temperatures as high as 300 ?C, greatly simplifying the workflow while maintaining superior quality digestions.
The miniDOAS: Low Cost, High Performance Contactless Ammonia Measurements
Knowledge of atmospheric ammonia concentrations is important, but ammonia is difficult to measure. We report here on the development of a low-cost ammonia measuring differential optical absorption spectroscopy (DOAS) instrument, based on a small sized and low priced spectrograph.
