Maximizing and validating the stability of a drug is critical throughout its life cycle, beginning in the development phase of an active pharmaceutical ingredient (API), continuing through the final ...

Table 1. Factors to consider in real-time stability study (click to enlarge). Figure 1. Effect of material change on stability profile (click to enlarge). Figure 2. Correleation of stability failure ...

Stability testing is essential in the pharmaceutical and biopharmaceutical industries. These tests are performed to evaluate the stability of drug products under various environmental conditions. Once ...

Many voltage regulators are of the fixed output variety and include the voltage divider internal to the regulator. There are definite advantages to this approach, which allows active voltage trimming ...

The Rancimat technique is an accelerated aging test. Air is passing through the sample in the reaction vessel at a constant high temperature and fatty acids are oxidized in this process. Volatile, ...

Laboratory-based design verification testing (DVT) of combination products and medical devices must be performed to demonstrate that the device meets the performance requirements that were set in the ...

Engineers often use SPICE simulations for operational amplifiers to look at the stability of a proposed circuit. SPICE simulations are particularly frequent for high-speed amplifier applications where ...

Among the first decisions to be made when initiating a composites testing program is the selection of test methods to follow. Unless performing highly customized testing, it’s usually not difficult to ...
