1、The test results of the investigation。

The standard piece are provided by SONY company, by the use of the PVC standard has been adopted by ICP testing.

It is used in the standard curve is relatively simple, but the unknown label contains large amounts of Br, Sb, Sn Br Pb, difficulty is very big impact, Sb, Sn Cd ’s influence is very large, if the hardware is not precise enough or software algorithm is not science, it is difficult to accurately test results. UTX series high precision electric refrigeration Si-PIN detector, energy resolution of up to 139eV, for accurate measurements provide a good basis for the hardware. UTX series is the use of the United States of America ’s new multiple algorithm software, scientific, accurately calculate the elements of interest.

The UTX850 apparatus with Shimadzu EDX720 contrast test results are as follows
