Clean your test sieves to maintain accurate results
A standard process in analytical laboratories is sieve analysis, the practice of accessing the particle size distribution of a granular material. The trouble is, sieves prove quite the challenge to clean thoroughly enough to get all the contaminants out of the mesh. Every last grain stuck in the sieve must be removed to gain accurate analysis. A solution has been found in the use of ultrasonic ...

Cell Penetrating Peptides: Definition and Synthesis
What are cell penetrating peptides? Cell Penetrating Peptides (CPPs) are short peptides that have the ability to cross biological membranes and enter cells. They are able to traverse the cell membrane by directly translocating across the lipid bilayer or by exploiting endocytic pathways. CPPs are generally composed of 5-30 amino acids and are known for their high cell-penetrating efficiency and ...

Find out the principles of ELSD and the gas delivery solutions for ELSD from a nitrogen gas generator
ELSD is one of the most common detectors used with HPLC and is preferred to other detection methods for analyses such as carbohydrate, natural sugars and polymer analysis as well as being used for a wide range of other applications. As a mass-detector, ELSD has advantages over some other methods of detection such as UV detection that require analytes to contain chromophores and it is unaffected ...
