What is ISO 6468 — Determination of certain organochlorine insecticides, polychlorinated biphenyls, and chlorobenzenes about? 
ISO 6468 describes a method for determining certain organochlorine insecticides, polychlorinated biphenyls (PCBs), and chlorobenzenes (except the mono- and dichlorobenzenes) in drinking waters, groundwaters, surface waters, and wastewaters.
ISO 6468 applies to samples containing up to 0,05 g/l of suspended solids. In the presence of organic matter, suspended matter, and colloids, interferences are more numerous and consequently, the detection limits are higher.
The method described in this ISO 6468 only gives information on specific PCB compounds but no information on the level of total PCBs.
Who is ISO 6468 — Determination of certain organochlorine insecticides, polychlorinated biphenyls, and chlorobenzenes for? 
ISO 6468 on the Determination of certain organochlorine insecticides, polychlorinated biphenyls, and chlorobenzenes are useful for: 
- Wastewater collecting systems 
- Wastewater treatment plants 
- Plants treating industrial wastewater 
- Water supply treatment plants  
Why should you use ISO 6468— Determination of certain organochlorine insecticides, polychlorinated biphenyls, and chlorobenzenes? 
Gas chromatography (GC) is an analytical technique used to separate the chemical components of a sample mixture and then detect them to determine their presence or absence and/or how much is present.
ISO 6468 provides methods based on the gas chromatography benefits in determining certain organochlorine insecticides, polychlorinated biphenyls, and chlorobenzenes.
ISO 6468 describes methods and procedures for determining certain components in raw water with the gas chromatographic method after liquid-liquid extraction.
ISO 6468 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The test methods and procedures provided by ISO 6468 assist you in the determination of organochlorine insecticides, polychlorinated biphenyls, and chlorobenzenes in water and ensure reducing the risk of severe health issues.
With obedience and compliance to ISO 6468, you can enhance the efficacy of the water and manufacture a standardized product.
