Analysis Standard Solution

Hengyuan Fine Chemical Analytical Standard Solutions are engineered for precise testing in industrial, environmental, and laboratory applications, covering parameters such as pH, conductivity, heavy metals (e.g., lead, cadmium), and organic pollutants (VOCs, polycyclic aromatic hydrocarbons). Certified under CNAS ISO 17034:2016 with a concentration accuracy of ±0.3% (verified by ICP-MS/GC-MS), the products provide COA (Certificate of Analysis). Compatible with laboratory instruments (e.g., atomic absorption spectrometry, HPLC) and portable detection systems, they comply with EPA 6010D, GB/T national standards, and related regulations, meeting trace analysis and compliance quality control requirements for environmental monitoring stations, pharmaceutical enterprises, and third-party testing institutions.
