Good news! Weiyel has successfully applied for 9 national reference materials

Weiyel has successfully obtained approval for nine national Class II reference materials, marking another breakthrough in the field of reference material application! This successful application signifies a new level of advancement in Weiyel's R&D and innovation capabilities.

Ethylbenzene Solution Reference Material in Carbon Disulfide:Primarily used for determining ethylbenzene content in environmental quality and upstream and downstream ethylbenzene products, and also for evaluating laboratory measurement methods.

Methylparathion Solution Reference Material in Anhydrous Ethanol:Primarily used for the verification and calibration of flame photometric detectors (FPDs) in gas chromatographs, and also for analytical method validation and evaluation, measurement process quality control, and certification evaluation.

Sodium Chloride Titration Solution Reference Material:Primarily used for the determination of silver ions, etc., and widely applied in water quality analysis (such as the detection of chloride ion content in drinking water), chemical product quality control, and laboratory titration analysis. The development of this series of reference materials will meet the needs of laboratory capacity analysis, proficiency testing, quality control, certification assessment, and analytical method validation and evaluation in environmental, food, chemical, and educational fields.

Sucrose aqueous standard solution: mainly used by food inspection, health and epidemic prevention departments for method evaluation and confirmation, quality control in sugar content analysis, and can also be used for verification and calibration of precision saccharimeters based on the refractive principle.
