Know about the different stages of the HPLC analytical method development in pharmaceutical analysis. 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.

Activated Carbon Filter and Increase in Efficiency for Water System

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.

Transport Validation for Pharmaceutical Products

In the past, it was not important to validate the transportation of the pharmaceutical products but now it is recommended by all major regulatory agencies. Storage conditions during transit of the pharmaceutical products should be validated because it may affect the product stability.

Incubation of Petridishes in Inverted Position

Petri dishes were first used by German physician Julius Petri in 1887. He covered one culture plate to another plate to prevent the contamination. Before him the culture plates were covered with the glass bell jars. All of we know that the Petriplates are incubated in inverted position but this question arises in our mind that why these plates are incubated in inverted position?

Different Mesh Sizes Used in Pharmaceuticals and Their Conversion

Sieves and screens are widely used in the pharmaceutical manufacturing as well as in the quality control to determine the particle size of the raw materials. Mesh is the most common measurement unit used for the sieves and screens. Generally 40 to 400 mesh sieves are used in pharmaceutical manufacturing during shifting and milling of raw material.

Maintenance of Pharmaceutical Clean Areas: FDA Recommendation

Maintenance of clean area has its importance in sterile manufacturing. Sterility of the sterile products is the most important factor for the product quality and it can be achieved only by the proper maintenance of the manufacturing area. Areas surrounding the core manufacturing area are known as supporting areas.

Effectiveness and Criteria to Replace the UV Lights
