Easotope software archives, organizes, and analyzes mass spectrometer data. It is currently oriented toward clumped CO 2 analysis but is also useful for bulk CO 2 work and expandable to other isotopic systems. El-MAVEN Open-source Desktop software by Elucidata processes labeled LC-MS, GC-MS and LC-MS/MS data in open-formats (mzXML, mzML, CDF).
The ice thickness is maintained throughout the entire experiment by keeping the relative humidity of the enclosure at 10%±2% via the nitrogen purged enclosure. [2] Previously, ice was used as a matrix in IR-MALDI experiments; [11] however, the ion yields for such experiments have been very low. The electrospray post-ionization employed in IR ...
The term matrix-assisted laser desorption ionization (MALDI) was coined in 1985 by Franz Hillenkamp, Michael Karas and their colleagues. [3] These researchers found that the amino acid alanine could be ionized more easily if it was mixed with the amino acid tryptophan and irradiated with a pulsed 266 nm laser.

It is a variation of matrix-assisted laser desorption/ionization (MALDI). [ 1 ] [ 2 ] In MALDI, the sample is mixed with a matrix material and applied to a metal plate before irradiation by a laser, [ 3 ] whereas in SELDI, proteins of interest in a sample become bound to a surface before MS analysis.

Mass spectrometry is a scientific technique for measuring the mass-to-charge ratio of ions. It is often coupled to chromatographic techniques such as gas-or liquid chromatography and has found widespread adoption in the fields of analytical chemistry and biochemistry where it can be used to identify and characterize small molecules and proteins ().
