HORIBA Ltd. is ready for when the China RoHS is introduced this coming spring with our multiple model lineup with microanalysis capability and higher sensitivity

27 February 2007


HORIBA Ltd. has strengthened its lineup of X-ray analytical instruments to meet expected increases in demand for hazardous substance analysis in response to the Administration on the Control of Pollution Caused by Electronic Information Products or "China RoHS," which comes into force in March this year. With higher sensitivity and shortened analysis time to up to 1/4 that of conventional equipment, our new models (XGT-1700WR series), well suited for production line use, will be placed on the market on March 1, 2007. The RoHS to be implemented in China following the EU Directive widely applies to semiconductor manufacturing equipment and medical devices, as well as home appliances. Demands for analysis in electrical, electronic and material fields are therefore anticipated to rise in terms of business sectors, analysis types and quantities. To fulfill such various needs, we are pleased to offer analyzers with microanalysis capability with higher sensitivity plus shorter analysis time, and further, with the function of allow/reject assessment based on the automatic setting of optimal measuring conditions by sample type.

Newly added to the lineup of X-ray analytical instruments that determine types and quantities of elements contained in a sample by irradiating it with an X-ray beam are two models of the 1700WR series, which are suitable for production line use. By improving sensitivity by 5 times that of existing models, analysis time has been shortened to up to 1/4 of that previously required. Demands for X-ray analyzers have experienced a sharp rise since the adoption of the RoHS Directive in the EU; shorter analysis time allows execution of a greater number and type of analyses in less time. Additionally, in these new models, 10 types of optimal analyzing conditions by sample type are preset. Optimal analysis can be performed by simply clicking the most appropriate condition for the sample among the preset selection. Such an advance was made possible by the know-how accumulated during our over 10-year experience in the supply of analytical instrumentation. These new models are also capable of assessing the hazardous substance concentrations as allowable or not, printing out the assessment results and storing them as data. The 1700WR series models, readily used by non-experts of analysis in production lines, represent advancement from an “analyzer” to an “assessor.”

The already marketed analyzers designed solely for microanalysis (minimum measurable sample area: 1.2 mm in diameter) with our original technical know-how (XGT-1000WR series); the aforementioned newly introduced models with higher sensitivity and shorter analysis time, as well as microanalysis capability (minimum measurable area: 3.0 mm in diameter); and the XGT-5000 series models, which are capable of locating the target substance via a color display of an image of distribution of substances contained in the sample, as does an electron microscope, coupled with the use of an ultra-narrow (10 µm) X-ray beam, which is narrowest in our industry. The above three types of equipment in our product lineup will contribute to attentive and appropriate handling of expected analysis demand increases in type and quantity in the electrical and electronic fields, in response to the initiation of the China RoHS, and also in the automobile industry where the full implementation of the End of Life Vehicles (ELV) Directive is to be completed.


<About the product>
The XGT-1700WR series comprises two models, -1700WR and -1710WR. The former is equipped with a detector cooling system using liquid nitrogen; the latter has a liquid nitrogen-free pulse tube cooling system.

Both models are suited for production site use, with large-sized sample chambers that enable analysis of a 460 × 360 × 149 mm sample.

This series of hazardous substance analyzers is the first of its kind equipped with dual filters, i.e., a separate filter for the primary X-ray (irradiates a sample) and the secondary X-ray (emission of X-ray characteristic of element, generated by excitation of the sample). This setup decreases their mutual interactions, thereby upgrading sensitivity by 5 times and shortening analysis time to up to 1/4. More samples can thus be analyzed in less time. In addition, optimal analyzing conditions by sample type are preset using our own know-how in actual equipment operation accumulated with the cooperation of our users, electrical appliance and automobile manufacturers. This saves complicated operational procedures, allowing production line staff without previous relevant experience to readily execute analysis. These models are also capable of automatically assessing the concentrations of hazardous substances as allowable or not, printing out the results in report form, and storing the data using a data management software. The product performance will contribute to improved efficiency in work operation in the production site.

Simultaneously with the release of the XGT-1700 series, two newer models with 5-time higher sensitivity (XGT-5700WR and -5710WR) also become available for the two-dimensional imaging analyzer, which can identify the location of a target substance via a color display of an image of distribution of substances contained in the sample, as does an electron microscope, coupled with the smallest X-ray irradiation diameter (10 µm) available in our industry.
