2016年1月6日，由工業和信息化部、發展改革委、科技部、財政部、環保部、商務部等八部門聯合公布了《電器電子產品有害物質限制使用管理辦法》[1]（第32號令，即中國RoHS2.0），并于2016年7月1日正式實施；相對于2006年實施的《電子信息產品污染控制管理辦法》（也稱中國RoHS1.0），新版RoHS2.0在適用范圍、限制使用有害物質管理方式等方面做了重大調整，具體如下：
序號 | 主要修訂 | 修訂內容解析 |
1 | 擴大規章的適用范圍并修改規章名稱 | 將調整對象由電子信息產品擴大為電器電子產品，并將規章名稱修改為《電器電子產品有害物質限制使用管理辦法》。同時，《辦法》對電器電子產品的含義做出了規定。 |
2 | 擴大限制使用的有害物質范圍 | 借鑒歐盟RoHS指令和其他國家的通行做法，增加了限制使用的有害物質，將“鉛”、“汞”、“鎘”分別修改為“鉛及其化合物”、“汞及其化合物”、“鎘及其化合物”，將“六價鉻”修改為“六價鉻化合物”。 |
3 | 增加有關科技、財政政策支持的規定 | 新版RoHS規定：國家鼓勵、支持電器電子產品有害物質限制使用的科學研究、技術開發和國際合作，積極推廣電器電子產品有害物質替代與減量化等技術、裝備。 |
4 | 完善產品有害物質限制使用的管理方式 | 電器電子產品有害物質限制使用采取目錄管理的方式，由工信部商發展改革委等7部門編制“達標管理目錄”，不再編制“重點管理目錄”。同時，建立合格評定制度，對納入“達標管理目錄”的電器電子產品按照合格評定制度進行管理。合格評定制度由認監委依據工業和信息化部的建議并會同工業和信息化部制定。工業和信息化部根據實際情況會同財政部等部門對合格評定結果建立相關采信機制。 |
新版RoHS 2.0的適用范圍擴大為電器電子產品，幾乎涵蓋了所有家電產品，并且對進出口產品與國產一視同仁，具體涉及限制物質清單如下：
序號 | 物質名稱 | 限量要求 |
1 | 鉛及其化合物 | ＜0.1% |
2 | 汞及其化合物 | ＜0.1% |
3 | 鎘及其化合物 | ＜0.01% |
4 | 六價鉻化合物 | ＜0.1% |
5 | 多溴聯苯（PBB） | ＜0.1% |
6 | 多溴二苯醚（PBDE） | ＜0.1% |
7 | 國家規定的其他有害物質 |
|
針對以上限制物質清單的檢測，《GB/T 26125-2011 電子電氣產品 六種限制物質的測定》[2]指定了上述有害物質的檢測手段和方法，天瑞儀器的氣相色譜質譜聯用儀（GC-MS 6800）可用于新版RoHS2.0中多溴聯苯和多溴二苯醚的定量分析。

Eight technical advantages：
First, FP basic parameter method
The FP (Basic Parameters) algorithm is an effective method for X-ray fluorescence spectrometry analysis. It can perform qualitative and quantitative analysis of the elemental components of the sample with little or no standard sample, and can also analyze the thickness of the coating or coating.It is well known that the biggest problem with X-ray fluorescence analysis is that elemental fluorescence intensity is affected by coexisting elements (matrix absorption and enhancement effects) and is not usually linear with content. The basic parameter method has already taken into account the matrix effect in the calculation of the spectrum, and the linear relationship between the calculated content and the known content can be obtained. Using a few known sample calibration algorithms to eliminate systematic errors can achieve accurate quantitative results.
Second, polarization secondary target excitation technology
The polarization secondary target excitation technology can remove the scattering background to the maximum extent, improve the signal to noise ratio, and reduce the detection limit of the detector. Assuming that the x-ray generated by the anode of the x-ray tube is non-polarized and is incident on the target (scattering body) in the z-axis direction, the scattered beam propagating along the y-axis is linearly polarized light. The electric field vector vibrates in the v plane and the vibration direction is parallel to the X axis. The sample placed on the y-axis is excited by polarized light, producing unpolarized fluorescent x-rays. Since the sample and the sample support do not generate scattered radiation in the X-axis direction, placing the detector on the x-axis can fully utilize the polarization effect and reduce the background caused by the elastic and inelastic scattering of x-rays.
Third, ultra-short optical design
From the X-ray generator to the sample, the X-ray fluorescence emitted by the sample to the detector is called the light path. The shorter the distance traveled by the optical path is, the less interference will be caused. Skyray Instrument designed an ultra-short optical path technology to ensure the accuracy of light element detection results, and is particularly suitable for RoHS-compliant halogen-free instruction detection.
Fourth, precision machinery design
The micro-level positioning, micro-scanning analysis, the point-to-point centering of the spatial micro-sized spot and the determination of the spatial micro-focus spot position have been truly achieved. A translation and rotation switching position device realizes position rotation switching in a small space, avoids the large space required for the linear motion and the common rotation movement, because the problem of lengthening of the optical path caused by the inability to fit is eliminated.
Five, no standard technology
XRF test and analysis instruments are generally used for the comparison test of standard samples, which are subject to the quality of the standard samples during the test. Tianrui Instrument's original non-standard technology can carry out all-element analysis without standard samples, leading the development trend and trend of the industry.
Sixth, secondary target excitation technology
XRF test and analysis instruments are generally used for the comparison test of standard samples, which are subject to the quality of the standard samples during the test. Tianrui Instrument's original non-standard technology can carry out all-element analysis without standard samples, leading the development trend and trend of the industry.
VII. Signal to Noise Enhancement Technology
Skyray's unique SNR enhancement technology can effectively remove noise signal interference and minimize element detection limits.
As shown in Figure SUPER XRF 1050, the determination of Pb in food can be as low as 0.59 ppm.
VIII. XRF Core Technology (Intelligent Analysis Software)
