HPLC for RoHS

High Performance Liquid Chromatography is a form of liquid analysis that measures the amount of compound within a sample. This form of analysis enables the measurement of very low levels of PBB and PBDE.

Benefits for RoHS

• Low level analysis (identification and quantification) of PBB and PBDE.

Additional Information:
To ensure the required homogeneity of the sample (per RoHS testing definition), samples need to be prepared via a standard solvent extraction. In addition, when quantifying flame retardants be sure to use the same producer for the sample and the calibrant. If you change producers, you will need to remain consistent by changing the calibrant.

High Performance Liquid Chromatography is a form of liquid analysis, where a sample is dissolved in the mobile phase and then injected into a reverse phase LC column which separates out each major constituent. Each component will diffuse through the stationary phase of the column at different rates. The sample is then passed though a photo diode array detector and it is the difference in light absorption between the mobile phase and the sample which generates a chromatogram of multiple peaks allowing identification and quantification of the various compounds in the sample.
