Long dan Xie gan pill is a traditional complex compound preparation with a long history for treatment of diseases, including hepatocolic hygropyrexia, dizziness, tinnitus, and deafness. Quality of products from different manufacturers may be varied. Since the current standard could not control the quality of products in a comprehensive and effective way, this study aimed at establishing a practical and convenient approach for holistic quality control of the preparation. This study included both qualitative and quantitative works to get information on the overall composition and main components, respectively. As a result, HPLC fingerprint (UV 240 nm) similarities of all fifty samples were in the range of 0.65∼0.99. Results indicated that there was a difference among products from different manufacturers. Additionally, ten characteristic peaks of the fingerprint were tentatively identified by LC-MS. Further chemometrics analysis was utilized to evaluate the products from different manufacturers. At the same time, the HPLC (UV 285 nm) multicomponent quantification result showed that contents of gentiopicrin, baicalin, baicalein, and wogonin were in the range of 0.61–5.40, 1.96–5.33, 0.10–3.40, and 0.046–1.16 mg·g−1, respectively. Data analysis verified the main different component of baicalein from the fingerprint statistical analysis. It is worth mentioning that the qualitative fingerprint and quantitative multicomponent determination were simultaneously accomplished by HPLC-DAD with dual channels. The study provided sound basis for improving quality control standards. This study also provided practical strategy for overall quality control of traditional Chinese medicines.

AbstractTo assess the quality of centrally prepared cytotoxics a global approach is being implemented by pharmacists. A risk analysis is performed, and then many in-process controls are proposed. The aseptic process and the material are also fully validated. Moreover the skills of pharmacy technicians are being checked and monitored over time. This short opinion paper discusses the place of in-process quality control within the quality system applied to cytotoxic preparations. It also discusses the pros and cons of analytical control of the final product versus continuous control of each preparation step by eye witness or an electronic device such as a camcorder. Finally the relevancy of controls is discussed in function of different cases and of the human and material resources available in the pharmaceutical technology cytotoxic unit.

The entire technological process, starting from ore mining to ending with the release of finished products, it is closely connected with the analytical control of each stage. Currently, the practice of analytical laboratories of large metallurgical enterprises, which include the Oskemen Metallurgical Complex LLP "Kazzinc", has firmly entered the physical and chemical or instrumental methods. These methods, which are characterized by rapidity, high selectivity and the ability to simultaneously determine several components, have replaced in most cases chemical ones. The article presents experimental data on the analysis of dump slag - the waste from metallurgical production of the Oskemen Metallurgical Complex LLP "Kazzinc"- by atomic emission method with inductively coupled plasma. Atomic spectral analysis are used in mining and geology, metallurgy, metalworking and chemical industries, etc. The analysis results were processed from the standpoint of the concept of uncertainty, which is very relevant in the practice of the analytical laboratory.

Quality being the competitiveness of the most important for the company's products and also because the quality has been the hope and desire of everyone, especially the consumer. Customers are not going to focus on a product / service only in terms of price but in good quality inherent in the product or service. Viewed from the importance of the quality of products, each company needs to spend quality, cost of quality is the cost refers to the cost incurred to prevent or expenses incurred as a result of producing a quality product. Efforts to improve the quality of the product will not run without the cost of quality control to overcome the problems faced by the company, where quality control can help the company determine the feasibility of the quality of products based on control limits have been set. This study aims to see how the cost of quality control and to analyze the efficiency of the implementation cost of quality control conducted by Aksan Bakery in Manado. Analysis of the data used is descriptive analysis with qualitative approach and using methods of presentation quality cost ratio analysis to assess the efficiency cost of quality. Based on analysis of the cost of quality control conducted by the company it appears that the cost of quality control conducted by the company do not meet the quality standards that have been set at 2.5% of sales, for the cost of quality issued by the company is greater than a predetermined quality standards, namely amounting to 13.89% of sales. This may imply that the cost of quality control has not been carried out efficiently. Keywords : Efficiency , Cost of Quality
