Water quality and specific parameters<\/strong><\/span><\/p>\n

Regardless of the type of water used, Magapor recommends that certain minimum must be met:<\/p>\n

Conductivity: <5 \u00b5siemens\/cm<\/p>\n

pH: 5-8<\/p>\n

Calcium hardness: <3 mg CaCo3\/liter<\/p>\n

Presence of bacteria: <30 cfu\/ml<\/p>\n

There are 3 organizations that speak of more specific parameters: American Society for Testing and Materials (ASTM)<\/strong>, College of American Pathologists (CAP)<\/strong>, the National Committee for Clinical Laboratory Standards (NCCLS)<\/strong> and a 4th, International Organization for Standarization (ISO)<\/strong>. All of them have published specifications for water quality and methods for preparing water of a specific quality. Between each organization there are slight differences between the standards, but in general the quality of the water is classified in Type I, Type II and Type III.<\/p>\n

Type I<\/strong>: This is the type with the highest purity level and generally requires a combination of deionization with distillation, filtration, and reverse osmosis. It is commonly used in the analysis of trace metals that require a minimum of ionized components.<\/p>\n

Type II<\/strong>: it can be obtained by various treatments, always taking into account the quality of the initial water. It is used for processes that require water free of organic contamination and pyrogens.<\/p>\n

Type III<\/strong>: Used for most general laboratory procedures, including preparation of stock solutions and washing of samples and analytical materials. It is obtained in various ways.<\/p>\n

Tipo II<\/strong>: se puede obtener mediante diversos tratamientos, siempre teniendo en cuenta la calidad del agua inicial. Es aquella que se utiliza para procesos que requieren agua libre de contaminaci\u00f3n org\u00e1nica y pir\u00f3genos.<\/p>\n

Tipo III<\/strong>: se utiliza para la mayor\u00eda de los procedimientos generales de laboratorio, incluyendo la preparaci\u00f3n de las soluciones madre y de lavado de las muestras y materiales de an\u00e1lisis. Se obtiene de diversas maneras.<\/p>\n<\/div>
