Why should you use BS EN 26777— Physical, chemical, and biochemical methods?
MAS is a spectroscopic analysis technique that determines the concentration of an element in a sample by atomizing the contents of the sample and measuring the absorbance of a wavelength specific to that element in the gas.
BS EN 26777 provides methods for characterizing water quality based on physical, chemical, and biochemical measures for determining the nitrite content in water using the molecular absorption spectrometry method.
BS EN 26777 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The test methods and procedures provided by BS EN 26777 assist you in the determination of nitrite in the water and ensure reducing the risk of severe health issues.
With obedience and compliance to BS EN 26777, you can enhance the efficacy of the water and manufacture a standardized product.
