For confirmatory studies, samples should be exposed to light providing an overall illumination of not less than 1.2 million lux hours and an integrated near ultraviolet energy of not less than 200 watt hours/square meter. When powder samples are involved, sampling should ensure that a representative portion is used in individual tests. For confirmatory studies, samples should be exposed to light providing an overall illumination of not less than 1.2 million lux hours and an integrated near ultraviolet energy of not less than 200 watt hours/square meter to allow direct comparisons to be made between the drug substance and drug product.Samples may be exposed side-by-side with a validated chemical actinometric system to ensure the specified light exposure is obtained, or for the appropriate duration of time when conditions have been monitored using calibrated radiometers/lux meters.If protected samples (e.g., wrapped in aluminum foil) are used as dark controls to evaluate the contribution of thermally induced change to the total observed change, these should be placed alongside the authentic sample. The intrinsic photostability characteristics of new drug substances and products should beevaluated to demonstrate that, as appropriate, light exposure does not result inunacceptable change. Works on 230 V AC single phase . confirmatory study are equivocal, testing of up to two additional batches should be conducted. NOW YOU CAN ALSO PUBLISH YOUR ARTICLE ONLINE. PLC based control system with 7" colour HMI. Similar sampling considerations, such as homogenization of the entire sample, apply to other materials that may not be homogeneous after exposure. Acceptance criteria: The exposure should not be less than desired exposure. 5.3.20.1Group leader shall review the print outs of photostability chamber including alarm log.
