Drying high performance liquid chromatography (HPLC) purification fractions, principally comprising water and acetonitrile, is a routine yet essential task in many laboratories. The requirement is to dry the samples to a powder form, such that samples can be accurately weighed, easily sub-sampled and redissolved.
The intensely manual practices of cleanroom classification and routine monitoring are time-consuming and prone to data errors. Particle counter performance and accuracy can vary widely, leading to inaccurate particle counting data.
Organic compounds and silica are the species least strongly held by the ion exchange resins. After a period of use, the ion exchange capacity of a purification pack starts to be used up and these compounds are released first even before the resistivity has fallen much below 18.2 MO-cm.
