Professional third-party laboratory

Green Clean has a professional third-party water quality testing laboratory located in the * Development Zone of Jinan City, positioning itself as a socially responsible and influential third-party environmental quality testing institution in China. The company has a professional testing team (including 1 researcher, 1 provincial-level laboratory qualification reviewer, 5 engineers or above, and 8 master's degree holders), all of whom have been trained and certified to meet the needs of their testing work.

The laboratory is equipped with multiple laboratories for microbiological testing, physical and chemical testing, spectral and chromatographic analysis testing, etc.

The laboratory is equipped with more than 50 large and medium-sized analytical instruments and equipment, including AA6300C atomic absorption spectrometer, AFS-933 atomic fluorescence spectrometer, GC2010 gas chromatograph, LC-20AT liquid chromatograph, ICS-900 ion chromatograph, PALL two worm analyzer, BH1216 II low background radioactivity alpha and beta measuring instrument, TU1810 UV visible spectrophotometer, etc. The instruments and equipment that require verification or calibration have been verified or calibrated by the legal metrology unit Shandong Institute of Metrology, and their status has been marked with three color identification after confirmation. The verification and use of equipment and instruments comply with the requirements of qualification certification.

The company's laboratory currently has a laboratory qualification certification scope of 885 testing items in 29 categories, including 216 non repetitive items. There are mainly 109 types of surface water, 39 types of groundwater, 106 types of domestic drinking water, as well as secondary water supply, drinking water purification, urban water supply, urban sewer sewage, sewage treatment plant effluent, urban miscellaneous water, landscape environment water, comprehensive discharge sewage, catering industry sewage, soil, sludge, soaking water, water treatment agents, activated carbon, etc. *It can meet the needs of government regulatory departments and various sectors of society in environmental testing.

Since its establishment, the company's laboratory has always adhered to the development concept of "honesty and trustworthiness in work, fair and scientific inspection, rigorous and meticulous technology, accurate and reliable data, and enthusiastic and thoughtful service". It continuously understands customer needs, strives to improve its own strength, and wins the recognition of relevant departments and the trust of customers with high-quality, fast, and accurate services.
