What are Omni Spray Ion Sources?
Omni Spray Ion Sources are a series of new revolutionary ionization sources incorporating the DESI technology (Desorption Electrospray Ionization) that was invented in the laboratory of Professor R. Graham Cooks, Purdue University.
What is the DESI Technology?
The DESI technology is a simple, sensitive, gentle,and versatile ionization method that allows for the direct sampling of surfaces without any sample preparation and under ambient temperature and pressure conditions. This patented technology (patent #7335897) was first disclosed in Science, Vol. 306, #5695,
pp. 471-473, October 2004.
How versatile are Omni Spray Ion Sources?
Omni Spray Ion Sources have been demonstrated in applications that range from the detection of explosives to proteomics. Therefore, with a single ion source scientists are able to analyze both large and small molecules as well as polar and non polar molecules from a variety of surfaces. Omni Spray Ion Sources are available to interface with most commercially available mass spectrometers.
What are the advantages of using Omni Spray Ion Sources?
Omni Spray Ion Sources are simple to operate; they eliminate the need for complex and time consuming sample preparation allowing for instantaneous results. In addition to the analysis of dried material on standard surfaces, such as glass or Teflon®, the Omni Spray Ion Source enables the examination of samples, in situ, such as plant or animal tissue. The spray solvent, and other variables, can be easily changed or optimized to increase selective performance.
The Omni Spray Ion Source is compatible for use with many of the instruments from:
