What specific actions have you taken to improve laboratory management?

What you said is also rather general; specifically, in addition to formulating relevant rules and regulations, it is necessary to assign responsibilities clearly to individual people

:lol :lol 1. Comply with GB/T15481－2005, and obtain CMA and CNAS certifications. 2. Conduct regular self-inspections. 3. Use instrument management software to oversee the instruments. 4. Carry out blind sample random inspections

To maintain and improve the level of laboratory testing, we mainly carry out the following tasks: 1. Establish and refine technical procedures and testing management systems, ensuring that testing methods are kept in line with any revisions to relevant standards； 2. Strengthen daily inspections of the implementation of technical regulations and inspection management systems ； 3. Conduct internal random inspections in the laboratory, including comparison with standard samples and blind analysis of samples within the laboratory ； 4. Conduct regular internal laboratory audits ； 5. Participate in **inter-laboratory comparisons whenever possible.

The system has been established; the key is to implement it!

To standardize inspection and testing procedures and behaviors, ensure the effectiveness and timeliness of production analysis, inspection, and testing activities, provide accurate quality data, and meet the requirements for quality system compliance. The inspection procedure is as follows: 1. Collect samples in accordance with the specified requirements, and keep proper records and labeling. 2. On-site sampling is conducted for purchased bulk raw materials and materials supplied internally. 3. For in-process inspections and tests, samples shall be taken at the production facility as specified. 4. For the inspection and testing of finished products, samples are taken at the production facility or designated location in accordance with quality management requirements. 5. Upon receiving a notice from the production workshop to take samples for temporary production, go to the designated location to collect samples as required. 6. For sampling operations, **standard or internal factory standards** must be followed. 7. After sampling, inspections and tests shall be carried out in accordance with the specified standards and test methods. Then prepare the retained samples as required and label them properly. During the testing process, it is necessary to strictly adhere to the operating procedures, and pay close attention to those factors that can affect the accuracy of the test results, controlling them strictly. Eliminate subjectivity and arbitrariness, and pay attention to the safety of sample handling and operational safety, as well as the sensitivity and stability of the instruments. During operation, one must not leave the work post without permission. 2. During the testing process, dual or multiple parallel measurements shall be carried out in accordance with the method specifications, and the results must meet the precision requirements of the method. Data processing and result calculation must follow the rules of numerical rounding; significant figures must not be discarded arbitrarily. 3. If abnormal test results or experimental deviations from the specified methods are detected, inspectors should not draw conclusions hastily. Instead, they must carefully examine the records, calculations, procedures, reagents, methods, and samples to identify the cause, and then conduct retests accordingly. 4. Quality records must be filled out carefully and promptly. All original records must be filled out in dedicated forms, in a neat, clear, truthful, accurate, and complete manner. Pencils are not allowed for taking notes; no random alterations, scribbling, drawing, or folding is permitted. When a typo occurs, use “－－” to cancel it out and make the correction above the “－－” by yourself. Draw a slash across the few blank entries that have not occurred; if an entire entry has not taken place, affix a \"Void\" stamp in that entry field. 5. Quality records are divided into five types: original analysis and testing records, analysis and testing report forms, daily analysis and testing reports, daily quality supervision reports, and product quality certificates. Laboratories involve two types: original records and report sheets. 6. Analytical data should be entered into the original records immediately; analytical results that require calculation should be recorded only after verification for accuracy. The original records of analysis and testing must be filled out by the analyst themselves, with review by other analysts on duty (a two-check system), and only after confirmation of accuracy can they be submitted. The analyst is responsible for the authenticity of the original records and the accuracy of the test results, while the reviewer is responsible for the accuracy of the calculation formulas and the calculated results. 7. After analyzing the data and confirming its accuracy through review (following a three-check system), promptly submit a report to the production unit or relevant departments. For defective data, it is also necessary to make corresponding markings in the shift handover log. The relevant personnel are responsible for the timeliness, accuracy, and completeness of the data reports, as well as for the quality of the reports. 8. Quality records should be compiled into volumes on a monthly, quarterly, or annual basis, properly labeled, and archived for storage. Quality records are generally retained at the analysis station for three months; after that period, they are sent to the laboratory’s quality record storage area for archiving. 9. Strictly comply with the relevant regulations regarding quality record and document management; quality records shall be properly kept. The original records of central control analysis are generally retained for one year, while the original records of raw material and product analysis, analysis and testing reports, daily analysis and testing reports, monthly quality supervision reports, and product quality certificates are generally retained for three years. 10. During storage, quality records should be protected from moisture, mold, and insect damage ； Be careful of loss and theft; pay attention to fire prevention and ventilation. The use and management of quality records must comply with the provisions of the quality system procedure documents. 11. Comply with the basic rules for laboratory analysis, testing, and experimental work. 12. During inspections by higher authorities, proper records should be kept, and the self-tested data should be compared with the results of those inspections in order to verify the capabilities of the testing laboratory as well as its inter-laboratory precision.
