2016年1月6日，由工业和信息化部、发展改革委、科技部、财政部、环保部、商务部等八部门联合公布了《电器电子产品有害物质限制使用管理办法》[1]（第32号令，即中国RoHS2.0），并于2016年7月1日正式实施；相对于2006年实施的《电子信息产品污染控制管理办法》（也称中国RoHS1.0），新版RoHS2.0在适用范围、限制使用有害物质管理方式等方面做了重大调整，具体如下：
序号 | 主要修订 | 修订内容解析 |
1 | 扩大规章的适用范围并修改规章名称 | 将调整对象由电子信息产品扩大为电器电子产品，并将规章名称修改为《电器电子产品有害物质限制使用管理办法》。同时，《办法》对电器电子产品的含义做出了规定。 |
2 | 扩大限制使用的有害物质范围 | 借鉴欧盟RoHS指令和其他国家的通行做法，增加了限制使用的有害物质，将“铅”、“汞”、“镉”分别修改为“铅及其化合物”、“汞及其化合物”、“镉及其化合物”，将“六价铬”修改为“六价铬化合物”。 |
3 | 增加有关科技、财政政策支持的规定 | 新版RoHS规定：国家鼓励、支持电器电子产品有害物质限制使用的科学研究、技术开发和国际合作，积极推广电器电子产品有害物质替代与减量化等技术、装备。 |
4 | 完善产品有害物质限制使用的管理方式 | 电器电子产品有害物质限制使用采取目录管理的方式，由工信部商发展改革委等7部门编制“达标管理目录”，不再编制“重点管理目录”。同时，建立合格评定制度，对纳入“达标管理目录”的电器电子产品按照合格评定制度进行管理。合格评定制度由认监委依据工业和信息化部的建议并会同工业和信息化部制定。工业和信息化部根据实际情况会同财政部等部门对合格评定结果建立相关采信机制。 |
新版RoHS 2.0的适用范围扩大为电器电子产品，几乎涵盖了所有家电产品，并且对进出口产品与国产一视同仁，具体涉及限制物质清单如下：
序号 | 物质名称 | 限量要求 |
1 | 铅及其化合物 | ＜0.1% |
2 | 汞及其化合物 | ＜0.1% |

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.
