Introduction to the differentiation of standard substances

2020-02-28 16:53:00

The standard material is relatively practical and can be applied well under actual working conditions, so it can be used for calibration and verification of measuring instruments, and then evaluate the accuracy of measurement methods, and can also be used for quality evaluation of measurement processes and laboratory measurement certification and measurement arbitration. The following is a small edition of Bolinda to introduce the distinction of standard substances.


The standard material that has passed the acceptance should be promptly affixed with the three-color label indicating its use status, so as to quickly and accurately grasp the use of the current standard material during the test.


And each time you use and put back, you can quickly browse to confirm the inventory of relevant standard substances, so that you have a good idea, ensure the safety inventory of commonly used standard substances, and can purchase in time.

 

The standard substances used in the laboratory usually come in many varieties with different properties, such as solid powder, liquid colored or colorless, and so on.


Storage conditions can be generally divided into freezing, refrigeration, room temperature. There are also some special storage requirements, such as the need for easily decomposed substances to be placed in brown bottles away from light, and this problem needs to be noted when configuration is used.


At present, we can divide the common standard substances used into organic and inorganic two categories, according to the type of standard substances using different letters to classify, and then further use numbers to distinguish.


In this way, even if the laboratory standard material more, we are not afraid of confusion, after the completion of classification can be placed in the standard material special test tube rack in accordance with the order, respectively according to the storage requirements into the room temperature, refrigeration, freezing of the special refrigerator, usually after use in time to return to the original position, easy to find usually.


The relatively special liquid reference material itself is small in quantity and the organic reagent is very volatile. We can pack it into 200uL liner tube and put it into 2mL brown automatic sampling bottle and store it under freezing conditions.


The above content is the introduction of the distinction of standard substances, standard substances is a national standard measurement of the determination of goods, in chemical measurement, biological measurement and other fields have been widely used. In this rapidly developing economic era, the state has standardized authoritative provisions for the measurement of some items, whether we are in work or life, we must follow the prescribed measurement methods to implement.
