Velocity and Position by Integral Method01:13

Velocity and Position by Integral Method

7.9K
If acceleration as a function of time is known, then velocity and position functions can be derived using integral calculus. For constant acceleration, the integral equations refer to the first and second kinematic equations for velocity and position functions, respectively.
Consider an example to calculate the velocity and position from the acceleration function. A motorboat is traveling at a constant velocity of 5.0 m/s when it starts to decelerate to arrive at the dock. Its acceleration is...

Development of Analytical Methods

2.2K
An analytical methodology can be divided into four sequential steps: technique, method, procedure, and protocol. A technique is a scientific principle that rationalizes a specific phenomenon through chemical measurements. Adapting a technique for analyzing a sample of interest is termed a method. The procedure outlines the directions for performing the analysis via an analytical method. The protocol is the detailed guidelines on the procedure, which should be strictly followed to obtain the...

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Phase Transitions: Melting and Freezing02:39

Phase Transitions: Melting and Freezing

15.2K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Dry Friction01:30

Dry Friction

989
Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible.
To illustrate this concept, imagine a wooden crate resting on a rough, non-uniform horizontal surface. When an external force is applied to...

In Vitro Drug Release Testing: Overview, Development and Validation

343
In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Area of Science:

  • Pharmaceutical Sciences
  • Analytical Chemistry
  • Biotechnology

Background:

  • Evolving regulatory standards (FDA, ICH Q5C, Eudralex, USP 1207.1/1207.2) necessitate advanced container closure integrity (CCI) testing methods for biopharmaceuticals.
  • Current CCI testing lacks universally accepted methods, presenting challenges for biopharmaceutical drug product evaluation.
  • Deterministic, quantitative, and objective CCI testing methods are required to meet new regulatory expectations.

Purpose of the Study:

  • To present a simple, model-based approach for validating container closure integrity (CCI) testing using headspace oxygen analysis.
  • To introduce a method for testing and verifying positive control vials for freeze-dried biopharmaceutical products in vials.
  • To demonstrate a life-cycle approach for CCI testing applicable during manufacturing, transportation, and storage.

Main Methods:

  • Development of a model based on Fick's law of diffusion, empirically corrected for Knudsen diffusion, to analyze headspace oxygen.
  • Consideration of storage conditions, including anaerobic/near-sealing pressure and temperature variations, and testing at multiple time points.
  • Validation of a method for testing positive control vials with known defects.

Main Results:

  • The headspace oxygen analysis method allows for rapid and non-destructive CCI testing.
  • Leak sizes as small as 0.2 μm can be detected within hours for standard vial sizes.
  • The model accounts for various storage conditions and time points, providing flexibility in testing.

Conclusions:

  • The proposed headspace oxygen analysis method provides a viable, efficient, and deterministic solution for CCI testing of biopharmaceutical products.
  • This method effectively demonstrates the critical barrier function of container closures throughout the product lifecycle.
  • The approach offers a reliable means to ensure the integrity and safety of biopharmaceutical drug products.
