As a recent trend, Halogen free is getting standard as well as RoHS and ELV directives. The well known Halogen free compliance can be non-use of Br as flame retardant. SEA1200VX is capable of measurement of small amount of Cl in resin as well as Br.
In addition to RoHS and ELV directives, halogen free products are also now being sought. A typical example is limits on the use of bromine compounds such as fire retardants. The SEA1200VX is able to measure, in addition to Br compounds, small amounts of chlorine contained in resin in conformance to conventional RoHS directives.
If a sample contains approximately 70ppm chlorine, we know that quantitative analysis is performed with good repeatability from a CV value of 3.6% for 10 repetitions, as the straight line in the figure below shows.
