HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC)
 
What is HPLC?

HPLC is used for separating, detecting and analyzing a variety of materials, including organic compounds and polymers.  HPLC size-exclusion chromatography separates molecules based on differences in their molecular weights.  Compounds varying in molecular weight from a few hundred to 10 million daltons can be easily separated.  At Acsion, three methods (laser light scattering, refractive index and UV-VIS) are used to detect the separated compounds and to characterize the components present.  This technique provides valuable data on formulations for batch to batch comparisons.
