Polymers, Natural Organic transportation

While, in this way, natural organic polymers literally dominated the existence and welfare of all nations, virtually nothing was known about their composition and structure. In each sector - food, clothing, transportation, communication, housing, and art - highly sophisticated craftsmanship developed which was sparked by human intuition, creativity, zeal, and patience and led to accomplishments which deserve the highest admiration of generations to come. 

Much LC-MS work is carried out in a qualitative or semi-quantitative mode. Development of quantitative LC-MS procedures for polymer/additive analysis is gaining attention. When accurate quantitation is necessary, it is important to understand in depth the experimental factors which influence the quantitative response of the entire LC-MS system. These factors, which include solvent composition, solvent flow-rate, and the presence of co-eluting species, exert a major influence on analyte mass transport and ionisation efficiency. Analyte responses in MS procedures can be significantly affected by the nature of the organic modifier used in the RPLC...
