How to analyse your drug in Biorelevant Media
Tip Image
After drug separation, the medium (containing dissolved drug) is best analysed by HPLC. HPLC avoids potential interference of the media and can identify possible drug instability

An improved Buffer Concentrate for preparation of FeSSIF-V2 has been developed to overcome the limitations of the previous maleic acid buffer system.
HPLC Parameters using FeSSIF-V2
Tip Image
To compare the HPLC profiles of FeSSIF-V2 prepared using a) FeSSIF-V2 Powder with FeSSIF-V2 Buffer Concentrate and b) FeSSIF-V2 Powder with buffer made from scratch, the following HPLC in-house method has been used throughout the different experiments.
Dissolution profiles in FeSSIF-V2
Tip Image
Dissolution runs, using USP Dissolution Apparatus 2, were carried out at 37°C with 900mL of the FeSSIF-V2 media.
Composition and properties of FaSSIF, FeSSIF and FaSSGF Media prepared from 3F Powder and Buffer Concentrates
Tip Image
FaSSIF, FeSSIF and FaSSGF dissolution media are prepared by diluting FaSSIF, FeSSIF, FaSSGF Buffer Concentrates with water and adding the required amount of 3F Powder®.
pH reproducibility of FaSSIF, FeSSIF and FaSSGF prepared from 3F Powder® and corresponding Buffer Concentrates
Tip Image
Variable pH of a solubility or dissolution medium is one of the most common and significant reasons for irreproducible results which affects decision making and interpretation.
