GRAM Laboratories offers services for conduct of preformulation studies. These studies are performed to gather in-depth knowledge about the physical and chemical characteristics of the active ingredient and eventually aid in the development and optimization.

The stability of active compounds in an excipient, and the process of storing the compounds without degradation, are the major concerns related to the development of new pharmaceutical products. Moisture sorption resulting in polymorphism or the formation of amorphous structures may affect dissolution kinetics and contravene licensing conditions. These effects can prevent certification of new medicines.Moisture content is an important feedstock quality in converting it into energy through biochemical or thermochemical platforms. Knowledge of moisture sorption relationship is useful in drying and storage to preserve the quality of feedstocks. Moisture sorption isotherms for potential feedstocks such as corn stover and big bluestem are missing. EMC values of corn stover and big bluestem were determined using static gravimetric technique with saturated salt solutions (ERH 0.12–0.89) at different temperatures (20, 30, and 40°C). Depending upon the ERH values, EMC values were ranged from 8.0 to 19.6 and 8.8 to 19.2% db for corn stover and big bluestem, respectively, and they followed typical type II isotherm found in food materials. Nonlinear regression was used to fit five commonly used three-parameter isotherm models (i.e., modified Oswin model, modified Halsey model, modified Chung-Pfost model, modified Henderson model, and the modified Guggenheim-Anderson-de Boer (GAB) model) to the experimental data. Modified Halsey emerged as the best model with high -statistic and values with low and and fairly random scattered residual plot for corn stover and big bluestem. These models can be used to predict the equilibrium moisture content of these feedstocks starting from harvesting, drying, preprocessing, transportation, storage, and conversion.
