General description

EPA 501/601 Trihalomethanes Calibration Mix is a multi-component solution which contains trihalomethanes EPA certified reference standards (CRMs) such as chloroform, bromodichloromethane, dibromochloromethane, and bromoform.
US EPA 500 Series methods are analytical methods for identifying and quantifying organic contaminants such as volatile organic compounds (VOCs), pesticides, synthetic organic compounds (SOCs), and trihalomethane disinfection byproducts (THMs) in raw source water, finished drinking water, and drinking water at all stages of treatment.

Application

EPA 501/601 Trihalomethanes Calibration Mix may be used as a CRM to determine the analytes such as chloroform, bromodichloromethane, dibromochloromethane, and bromoform in water samples by gas chromatography-mass spectrometry (GC-MS) technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
