Matrix-Assisted Laser Desorption/Ionization (MALDI)

Reduced graphene oxide films used as matrix of MALDI-TOF-MS for detection of octachlorodibenzo-p-dioxin.

A reduced graphene oxide (rGO) film was used as the matrix in the matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF-MS) for the detection of octachlorodibenzo-p-dioxin (OCDD) with a detection weight as low as 500 pg.

Dossier MALDI - TOF ■ Oligonucleotide analysis by MALDI - MS

Matrix-assisted laser desorption (MALDI) time-offlight (TOF) mass spectrometry (MS) has been successfully used for oligonucleotide sequence confirmation by mass analysis of fragments generated by concentration-dependent exonuclease digestion. This approach is particularly well-suited to the analysis of synthetic DNA due to the relatively short length of the DNA strands. Additionally, an importa...

Atmospheric pressure matrix-assisted laser desorption/ionization in transmission geometry.

In both atmospheric pressure matrix-assisted laser desorption/ionization (AP MALDI) and vacuum MALDI, the laser typically illuminates the analyte on the front side of an opaque surface (reflection geometry). Another configuration consisting of laser illumination through the sample backside (transmission geometry) has been used in conventional MALDI; however, its use and the number of reports in...
