In the “Early Drug Discovery Phase” of pharmaceutical development when there is a minimum amount of synthesized drug candidate, quick thermal analysis using a small amount of sample is the norm. The sample amount could be less than 3 mg. Because of the rush to identify possible drug candidates, analytical answers must be given within the day. The STA 6000 with its sensitivity of 0.1 µg allows minimum sample material to obtain reproducible results in half the time.
