The gas analyzer shows a solution for measuring the amount of solution by painting the tubes of a mixture of gas and air in oil. Detailed information on the production of vegetable oils, the cost of raw materials, the level of fat content of cotton seeds and the methods used to produce oil from cotton seeds. Methods for certification of vegetable oils, types of quality control, methods of testing and quality determination are presented. It was shown that the procedure for refined production of cottonseed oils and their types, as well as the state of the product classification of products based on the method of producing vegetable oils for consumer purposes, analysis of the sequence of refined oils and refining processes.

Objectives. Determination of target products and byproducts is necessary for the quality control of phthalonitrile monomer synthesis as well as production scaling and performing related kinetic studies. High-performance liquid chromatography (HPLC) is a simple and affordable method for quantitative chemical analysis, which also verifies the quality of raw materials. The objective of this study was to develop an HPLC technique for determining the composition of the reaction mixture in the synthesis of 1,3-bis(3,4-dicyanophenoxy)benzene (DPB).Methods. Reversed-phase HPLC was used to quantitatively analyze the reaction mixture.Results. A simple and rapid method for the quantitative HPLC analysis of phthalonitrile monomers and their mixtures with reagents was developed. Reaction times and the accumulation of byproducts were also studied.Conclusions. The successful performance of the developed technique allows us to recommend it for practical applications. The results obtained for reactors of different sizes have good convergence, and DPB synthesis was successfully scaled up to intermediate scale equipment.

<p><em>Telon oil is</em><em> one of </em><em> </em><em>the </em><em>traditional medicine in the form of </em><em> </em><em>liquid preparations that serves to provide a sense of warmth to the wearer. PT</em><em>.X</em><em> is one of the companies that produce</em><em> </em><em>telon</em><em> oil</em><em>.</em><em> To maintain</em><em> the quality of telon oil from PT.X</em><em> product</em><em>, required overall quality control that is starting from the quality control of raw materials, quality control process to the quality control of the final product. The purpose of this research is to know the application of Statistical Quality Control (SQC) in controlling the quality of telon oil in PT X. </em><em>F</em><em>inal product</em><em> quality</em><em> become one of the measurement of success of a process, so it needs a good quality control. SQC method used in this research is Pareto Diagram and Cause and Effect Diagram. Pareto diagram is a bar graph </em><em>that </em><em>show the problem based on the order of the number of occurrences of the most number of problems until the least happened. A causal diagram is often called a fishbone diagram, a tool for identifying potential causes of an effect or problem. The result of applying the method indicates that 80% defect is caused by unsuitable volume and on the incompatibility of Expired Date (ED) code. The damage is caused by several factors namely the method, labor, and machine while the most potential factor is the volume conformity to reduce the number of defect products.</em></p>

Current Guidelines

Standardization in Ayurvedic formulations ensures the establishment of standards for the quality and purity of raw materials, quality control during the drug manufacturing process, production of a good quality finished product, storage and distribution to maintain the quality of the final product. It is an essential tool for establishing quality control methods for Ayurvedic drugs. In Ayurveda, standardization has been well defined and documented in the classical and contemporary texts. Still, these have been written with an individualistic intent and not for industrial or commercial purposes.  Careful contemplation of the classical literature of Ayurveda was done, the current guidelines of WHO on standardization of herbal drugs, latest researches on the same via the internet were explored and examined in the purview of the newest standardization procedures.  In this article, an attempt has been made to bring to light the classical references related to standardization, the milestones in this on-going pursuit have been exhibited, with the use of the latest scientific methods being incorporated for a standardized Ayurvedic drug. It can be concluded from the review that standardization in Ayurveda is an on-going process where one needs to be strictly vigilant about the new scientific methods to study the fine chemical procedures and the intermediate compounds formed, but at the same time be aware of the classical. Ayurvedic methods concepts of the procedure. Asava-arista's medicinal characteristics of Ayurvedic classical dosage forms, liquid dosage forms based on self-generated alcohol with faster absorption, long shelf life, and increased market conformity have led to a continuous rise in demand. New fermentation methods and packaging innovations tend to have been embraced by many Ayurvedic processing units. The importance of standardization of such goods is underlined by these advances in manufacturing, distribution and storage. Therefore, it is of concern to examine the latest manufacturing situation and the standardization of the dosage type regarding the procedure and the consistency and effectiveness of the finished product. In addition to the effort to include criteria of consistency and standardization, the study consists of an overview and deliberates on the importance of improvements made to the conventional preparation processes, ingredients and material used in the process and the potential impact on its efficacy.
