Cobalt,Silicon and Silica GLAD films for SMALDI-MS,UTLC and Tissue Imaging

Reshma N Singh
2014
The films were also found to be highly reproducible in terms of SMALDI performance from, spot-to-spot and batch-to-batch.  ...  The GLAD technique produces films whose morphology in terms of pore size, density and shape can be dictated and is highly reproducible.  ...  Rather, the elution on GLAD films tended to follow a more size based order, with the smaller molecules eluting first, Figures 4.12 and 4.14.  ...
