| Heavy Metals in Plastic RMs - XRF Analysis | |||||||||||||
| European Communion (EC) directives have defined specific limits for heavy metals in plastic. Sets of PE and PVC have been designed for screening | |||||||||||||
| heavy metals to check for compliance with these limits. | |||||||||||||
| These sets of reference materials consist of 3 individual discs. Each disc is 31 mm in diameter and approximately 13 mm thick. The overall error of | |||||||||||||
| concentration of the added element is estimated at less than 4% relative at a 95% confidence level. Except, below 100 mg/kg, the estimated error is | |||||||||||||
| 5 mg/kg absolute at a 95% confidence level. | |||||||||||||
| There are many various additives combined with different plastics or polymers to give specific properties. XRF is often used to monitor these products. | |||||||||||||
| If you have a specific or special application need, please contact us for the possibility of custom made reference materials. | |||||||||||||
| These RMs are sold as sets only. | |||||||||||||
