Description

A sample storage cabinet with a standard substance management system

technical field

A sample storage cabinet with a standard substance management system according to claim 7, characterized in that the control system (501) is connected with an alarm, and when the user fails to enter the usage information as required, or fails to store the standard substance Returning to the correct position will trigger the alarm and whistle.

Background technique

Standard substances are an important prerequisite to ensure the normal operation of laboratory testing and calibration work, and the basis for effective traceability of laboratory data chains. The standardized storage and effective management of reference materials is an important part of the laboratory quality management system. A standardized and effective reference material storage-management system can improve laboratory testing capabilities.

technical problem

According to the requirements of the laboratory quality system, it is necessary to strictly supervise and control the whole process of purchase-storage-verification-use of reference materials, and it is necessary to establish inventory and receipt registration books to ensure the best quality of reference materials, so as to ensure Reliable stability of experimental data test results.

The storage of reference materials requires classified storage and special personnel to be responsible. The laboratory should set up a special storage area for standard materials, store them in categories according to the storage conditions required by the standard materials, and distinguish different types of standard materials according to their physical and chemical properties to prevent possible deterioration due to physical and chemical changes. , failure, etc. The standard material shall be kept by the standard material administrator, number the standard material according to the prescribed format, and clearly identify it (the level, name, quantity, technical index, whether the certificate is available, the validity period of the certificate statement, etc.) of the standard material, and shall be within the validity period use. Inventory information should be recorded in detail in registers, archives and related documents, and a corresponding standard substance storage system should be established to make the information on the storage process of standard substances traceable.

The laboratory should formulate a period verification procedure, and the verification procedure should specify the verification type, verification frequency, verification parameters, verification methods, verification personnel, verification standards, and judgment criteria for verification results of reference materials. After verification, if it is found that the quantity is not enough to meet the planned testing needs, purchase measures need to be taken; if it is found that it is about to expire or has expired, it is necessary to remove the expired standard substance from the laboratory and purchase a new standard substance.

In terms of use management, since reference materials are consumables in the laboratory, their quantity and status will change constantly, and good ledger management is the basis for reference material management. A list of laboratory standard substances and collection records should be formulated, registered when they are used, and information such as time of entry and exit, user, quantity used, purpose, etc. should be monitored, and the ledger should be updated at any time according to the situation of use.

However, in the prior art, laboratories use manual recording to manage standard substances, which has the following defects:

1. The personnel who use the reference material cannot know the status of the reference material in time. The standard substance management personnel are responsible for standard substance purchase, acceptance inspection, warranty, and period check. In many laboratories, there are many more standard substance users than standard substance management personnel, so information disconnection is prone to occur, causing users to use expired or non-compliant standard substances.

2. The user fails to register detailed information such as the use time, quantity, and purpose of the standard substance as required. Since the current laboratory uses the self-conscious and manual registration method of the user to record the use information of the standard substance, there is a lack of effective supervision measures for non-registration or non-compliance registration, which is not conducive to the efficient and standardized operation of the laboratory.
