Effective Solvent Systems for Separation of PTH-Amino Acids on Polyamide Sheet
Two dimensional thin layer chromatography on polyamide sheets is a useful method for identification of PTH-amino acids which have very close Rf-values. The solvent systems described here are particularly effective and have an edge over other solvent systems used for the separation of PTH-amino acids. The solvent systems provide a clear separation of all PTH-amono acids except lle / Leu in a...
متن کاملModification of Microfiber Synthetic Leather Base and Model by Collagen
Modified by the pretreated model with collagen under the crosslinking effect of glutaraldehyde, the moisture absorption of modified samples increased by 26.34% and 42.6%. The test results of SEM, AFM and DSC show that there was coating on the fibers modified with collagen, and the relative average roughness of the modified fabric decreased. Modification with collagen also affected the thermal p...
متن کاملEstimation of pigment magnitudes in synthetic leather by using scanner and artificial neural network
In the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. Initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. Then the pigmented samples were scanned, and the values of RGB of images were calculated. The artificial neural network (ANN) method used to make relation between RGB va...

متن کاملLeather
Leather is derived from the hides of skins of animals. It is a remarkably durable, strong and versatile material, which in its various forms has been made into objects ranging from African shields and drums to European saddles and kinky underwear. From as early as 2700 BC until fairly recently leather was also in the forefront of information technology with its use (as skins, vellum and parchme...
