Number: BWZ7382-2016

NameWater quality suspended matter control sample

Standard value: 100mg/L

Packaging specification: 500mL

Purpose: Water quality testing

1. Sample preparation:
This standard substance uses high-purity substances with purity determined values as solutes and ultrapure water as solvents at room temperature (20 ± 3). C is prepared using the weight capacity method in a clean laboratory.

2. Traceability and valuation methods:
This standard substance uses the verification value as the standard value and conducts quantitative verification using the gravimetric analysis method. By using preparation, measurement methods, and measuring instruments that meet the requirements of metrological characteristics, the traceability of the quality values of standard materials is ensured.

3. Characteristic values and extended uncertainty:

Storage conditions:

Store under cool, sealed, and dark conditions. Before use, it should be kept at a constant temperature of (20 ± 3) ℃ and shaken thoroughly to ensure uniformity. This standard substance should be used once after opening, and contamination should be strictly prevented during use.
