Along the way, you can find information on sample preparation for transmission experiments, the power of FTIR Microscopy and charts relating chemical structure to the infrared spectrum. Come back often, as this content is being ...
samples.On the other hand, protein band data obtained by SDS-PAGE could be used for distinctly identifying geographical origin of house nests and the production environment of EBNs.It is concluded that FTIR in combination with SDS-PAGE is a promising method for comprehensive determination of EBNs...
Stress here is on sample preparation and experiment optimization. Why is it important to know about different methods of sample handling? Certain techniques of sample handling are more effective than others for specific sample...
Comparison of methodologies for separation of fungal isolates using Fourier transform infrared (FTIR) spectroscopy and Fourier transform infrared-attenuate... Twenty distinct fungal isolates were analysed using three methods of sample preparation for FTIR spectroscopy and FTIR-ATR microspectroscopy to test ...

Peptide conformation assumed in multilayers depended on the method of sample preparation. Amide proton H/D exchange experiments showed that 60-80% of the NH bonds in these TMDs did not exchange with bulk water in 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) multilayers. FTIR results ...
Adhesive layers as thin as a few microns can be clearly observed in 50-micron thick polymer laminates without sample preparation. Introduction What are polymer laminates and what are they used for? Polymer laminates are film structures consisting of two or more layers adhered together to make a ...
