Testing Standards

GB/T6682-2008 Analytical Laboratory Water Standards Laboratory Water Testing

This standard is applicable to experimental water for chemical analysis and inorganic measurement analysis.

Appearance: The visual appearance of water used in the analysis laboratory should be a colorless and transparent liquid

Level: The raw water used for analyzing laboratory water should be drinking water or water of appropriate purity

The water used in the analysis laboratory is divided into three levels: primary water, secondary water, and tertiary water

1. Primary water: Primary water is used for analytical tests with strict requirements, including tests with particle requirements. For example, water for high-performance liquid chromatography analysis

Primary water can be treated with secondary water through quartz equipment distillation or exchange mixed bed treatment, followed by 0.2 μ M microporous filter membrane filtration is used to produce

2. Secondary water: Secondary water is used for inorganic measurement analysis and other experiments, such as water for atomic absorption spectroscopy analysis

Secondary water can be prepared by multiple distillation or ion exchange methods

3. Tertiary water: Tertiary water is used for general chemical analysis tests

Tertiary water can be prepared by distillation or ion exchange methods

Water quality specifications for analysis laboratory water:

Level 1: conductivity, absorbance, and soluble silicon.

Secondary: conductivity, content of oxidizable substances, absorbance, evaporation residue, soluble silicon

Level 3: pH range, conductivity, content of oxidizable substances, and evaporation residue

Bai Jian Wang Research Institute is committed to creating water quality testing and laboratory water testing
