• Circular Dichroism Spectrometry for the Analysis of Amphetamines (Lab Equipment and Scientific Instruments)
  From this Article:

  Amphetamines are synthetic drugs that stimulate the central nervous system. They are structurally similar to ephedrine, a natural stimulant found in plants and to the hormone adrenaline. They are... (View Full Article)
• Detection of Amino Acids Using HPLC with CD Detection (Chromatography)
  From this Article:

  A tetrahedral carbon atom with 4 distinct constituents is said to be chiral. Chirality describes the ability of a molecule to rotate the plane of polarized light either to the right (dextrorotatory)... (View Full Article)
• Detection of Chiral Compounds Using HPLC with CD Detection (Chromatography)
  From this Article:

  Chiral detectors provide valuable information since they only respond to optically active compounds. This allows the researcher to differentiate enantiomers. A sensitivity comparison between the two... (View Full Article)
• Detection of Chiral Drugs Using HPLC with CD Detection (Chromatography)
  From this Article:

  Many molecules made up of the same number and type of atoms come in two forms commonly referred to as left-handed and right-handed isomers. This is not just some interesting quirk of nature:... (View Full Article)
• Detection of Nitroarenes in Diesel Exhaust Using HPLC with UV and Fluorescence Detection (Chromatography)
  From this Article:

  A family of polyaromatic hydrocarbons (PAHs) known as nitroarenes are present in automobile exhaust. These species are known to be highly mutagenic and carcinogenic. Thus, it is very important to... (View Full Article)
• Dispersive Raman for the Identification of Contaminant Particles in Ink Jet Cartridges (Lab Equipment and Scientific Instruments)
  From this Article:

  Statistics have long supported the dominance of inkjet printing. From sales of $500 million in the early 90's to a record-breaking $14 billion in inkjet cartridge sales projected in 2001. Today, 7 out... (View Full Article)
• Fluorescence Detection of Counterfeit US Currency (Lab Equipment and Scientific Instruments)
  From this Article:

  United States currency is the most counterfeited currency in the world with Canadian money a close second, these currencies popular due to their status as a 'hard' currency, similar to gold. Large... (View Full Article)
• Gemstone Identification Using Raman Spectroscopy (Lab Equipment and Scientific Instruments)
