Introduction of reagent grade ammonia

Reagent grade ammonia is a high purity ammonia solution that is commonly used in laboratories and scientific research fields. Compared with ordinary ammonia, reagent grade ammonia has higher purity and stricter quality control standards to ensure the accuracy and reliability of experimental data. It is commonly used in analytical chemistry, biochemical experiments, mass spectrometry, and other fields that require accurate and reproducible experimental results.
Reagent grade ammonia is prepared through a rigorous purification and testing process to remove possible impurities and ions. In the laboratory, it is commonly used for operations such as neutralizing acidic solutions, adjusting reaction pH, and dissolving solid samples. Due to its high purity and stability, reagent grade ammonia is an important acid-base reagent in the laboratory. When using it, it is also necessary to follow safe operating procedures, wear appropriate protective equipment, and avoid direct contact with skin and eyes.

Uses of reagent grade ammonia

2, Sample pretreatment: In the process of chemical analysis, reagent grade ammonia can be used for sample pretreatment, such as neutralizing acidic samples, extracting analytes, etc., to prepare for subsequent analysis.
3, Protein solubilization: reagent grade ammonia can be used in biochemical experiments to solubilize proteins, peptides and other biomolecules for further experimental operations.
4, Mass spectrometry analysis: Reagent grade ammonia is used in mass spectrometry analysis for ionization and alkalization of samples, which helps to produce stable mass spectrometry signals.
5, DNA / RNA extraction: in molecular biology experiments, reagent grade ammonia can be used for DNA and RNA extraction and purification.
6, solution preparation: reagent grade ammonia is commonly used in the preparation of various standard solutions, calibration and inspection of analytical instruments to ensure the accuracy of experimental data.
7, Drug research: In drug synthesis and research and development, reagent grade ammonia can be used as a reactant, neutralizer or solvent, involved in the preparation and analysis of drugs.
8, Environmental monitoring: reagent grade ammonia is used in the treatment of environmental samples to neutralize or adjust the pH of the samples for accurate environmental monitoring.
9, analytical chemistry: in analytical chemistry, reagent grade ammonia can be used to calibrate the instrument, calibrate the analytical instrument, adjust the reaction conditions and so on.
10, Laboratory teaching: In teaching experiments, reagent grade ammonia can be used to demonstrate acid-base neutralization, pH adjustment and other experimental phenomena.

Precautions for reagent grade ammonia

1, Personal protection: Be sure to wear appropriate personal protective equipment, such as lab coats, goggles, gloves, etc., to reduce the risk of direct contact during operation.
2, ventilated environment: when operating reagent grade ammonia, ensure that the laboratory is well ventilated to prevent the accumulation of ammonia and protect the health of the operator's respiratory system.
3, Avoid inhalation of gas: Avoid contact with ammonia gas, especially do not inhale the gas directly. Try to use a pipette or instrument to transfer the liquid when operating.
4, Avoid eye contact:
Avoid contact of reagents with eyes, if accidentally splashed in the eyes, immediately flush with water and seek medical help.
5, Stable storage: Store reagent grade ammonia at a stable temperature to avoid temperature fluctuations that cause the liquid to volatilize or decompose.
6, Separate storage: Store reagent grade ammonia separately from other reagents to avoid chemical reactions, especially with acidic substances.
7, Avoid sunlight: reagent grade ammonia should avoid exposure to direct sunlight to prevent decomposition and concentration changes.
8, Labeling: Clearly mark the reagent name, concentration, preparation date and other information on the container to prevent confusion.
9, Safe disposal: The waste liquid after use should be disposed of safely according to the specified methods to avoid pollution of the environment.
10, Knowledge: Understand the nature, danger and emergency treatment of reagent grade ammonia before use to cope with possible accidents.
