2 Introduction To ELSD Leading the Way in ELSD Technology for More than 0 Years No one has more experience designing and manufacturing ELSDs than Grace Davison Discovery Sciences. Our customers' needs continue to drive the evolution of our ELSD design and development programs. 985 MK II 988 MK IIA 99 MK III 994 MK IIIA 996 ELSD ELSD LTA 000 ELSD ELSD ELSD 000ES Model 00 ELSD* *patent pending ELSD Advantages Universal Have confidence you re seeing everything in your sample Improve quantitative measurements Estimate purity more accurately Sensitive Detection limits in the low nanogram range Gradient Compatible Maintain stable baselines during steep gradients Alltech ELSDs simplify analysis of difficult compounds: pharmaceuticals excipients impurities amino acids phospholipids triglycerides fatty acids polymers surfactants carbohydrates nutraceuticals ELSD Detection Process:. Nebulization Column effluent passes through a needle and mixes with nitrogen gas to form a dispersion of droplets.. Evaporation Droplets pass through a heated drift tube where the mobile phase evaporates, leaving a fine mist of dried sample particles in solvent vapor.. Detection The sample particles pass through a cell and scatter light from a laser beam. The scattered light is detected, generating a signal. Copyright 008 Alltech Associates, Inc.
