Unlimited number of fractions | Two fractions, no waste |
Recovery typically below 80 % | Recovery up to 100 % |
EITHER high purity OR high yield | High purity AND high yield |
Isocratic or gradient | Isocratic (step gradient possible) |
High solvent consumption Can be as low as 10 % of batch consumption Very diluted product | Product concentration comparable with input concentration (feed) |
