Sterile area qualification and HVAC system qualification are two different things but most of the tests are same because HVAC system is qualified by its performance as quality of the area. Qualification document of the HVAC system and the sterile area should be prepared separately.
Sterile area can be qualified by applying following tests.
Sterile area can be qualified by applying following tests.

Sterile pharmaceutical preparations as injections are filled in glass vials. These vials should be cleaned properly before filling. Automatic vial washing machines are used to clean but the process of cleaning of the vials should be validated. The efficiency of these machines is verified by following tests.

Validation is a critical tool to assure the quality of computer system performance. Computer system software validation increases the reliability of systems, resulting in fewer errors and less risk to process and data integrity. Computer system validation also reduces long term system and project costs by minimizing the cost of maintenance and rework.

Analytical method development is considered as a critical process in pharmaceuticals. Availability of the different types of columns, operating parameters, mobile phase composition, diluent and pH values make it critical to develop an analytical method. A good analytical method should be simple, used column, mobile phase and buffer should be common. It can be done easily step by step.

Activated carbon filter is used to remove chlorine and organic matter from the water. It also removes the color and odor from the water hence the turbidity of water is also removed. It plays an important role in water purification systems where chlorine is added for decontamination. ACF is unable to remove the microbes and hardness.

Ultra violet radiation plays a vital role in pharmaceutical industry to control the microbial contamination in various stages including water system. No chemical is required to add in water; hence the procedure is environment friendly and safe. A high dose of UV radiation is required to control the microbes and the process can be reverse in the presence of light. This dose should damage their nucleic acid too enough so that it could not be repaired again by the process of photo-reactivation in the presence of light.

To control microbial growth, RO systems must be chemically sanitized on a regular basis. Prior to sanitation it is important to chemically clean the first-pass RO system. This will help to disrupt any biofilm that protects viable bacteria from contact with the sanitant. It also removes foulants that will react with and chemically deplete the sanitizing agent.

Sometimes during manufacturing, the in-process materials need to be hold for a period more than usual. Hold time study during manufacturing is validation of the hold time period of in-process materials. Now hold time study during pharmaceutical manufacturing has more importance because it is now recommended by the World Health Organization (WHO).
