Setting the benchmark for high sensitivity energy dispersive X- ray fluorescence analysis (EDXRF)

Kleve, Germany -- July, 2003
Instrument design
The new SPECTRO X-LABa 2000 is equipped with a 400 W Pd end window X- ray tube. The excitation radiation is optimized using various polarization and secondary targets, the spectral background is reduced by up to an order of magnitude. As detection system a state-of-the-art high resolution Si(Li) semiconductor detector is selected due its excellent sensitivity for low and high energies at the same time. With this it is possible to analyze traces as well as majors in a wide range of applications very precisely. The optimized instrument design is supported by unique integrated software and is accepted as the benchmark for high sensitivity EDXRF.

End window tube
The Pd taget end window tube allows to use the low energy radiation for excitation of the light elements such as Na- Cl.
Polarized excitation reduces the background in the spectrum, which is created by scattering the excitation radiation at the sample. In comparison to a standard setup this background is reduced and the reachable detection limits are drastically lower.
Si(Li) detection systems allow the analysis of low and high energy fluorescence radiation at the same time. The resolution at a level of < 155 eV for Mn Ka is one of the charcteristics of this system. The new detection systems in the X-Lab 2000 show an improved signal-to-shelf and signal-to-tail ratio by a factor of 2-5. This especially is beneficial for the analysis of trace element contents next to high concentration element fluorescence lines.
The universal X-Lab 2000 especially is used in those applications, where with little sample preparation a large number of elemental concentrations need to be determined. The element range covers all elements from Na- U. The unique data processing algorithms allow an analysis without any further input of sample matrix. For many elements LODs in the range of less than 1 mg/kg are reached.
Typically the instrument is used for environmental samples ( filters, soil, sludges ) as well as in the recycling industry. It also often is used in geological applications as well as in pharmaceuticals’ process control.
Using polarized excitation radiation together with a Pd target end window tube gives the advantage of a high sensitivity analysis of the element range Na- U in a wide range of matrices. The Si(Li) semiconductor detector with improved characteristics together with the analyzer software fit together to a instrument, which is regarded as the benchmark in high sensitivity EDXRF.

Simultaneous XRD and DSC (Differential Scanning Calorimetry) for Pharmaceutical Applications
Phase transitions between the various solid states have been the focus of much attention for several decades, and a variety of methods have been used to study their structural, thermal and kinetic properties. Among them, XRD and DSC (Differential Scanning Calorimetry) have proven to be two of the most useful techniques, and to be complementary to one another. Parallel measurements of different specimens using XRD and DSC, and a combination of both data are one of the popular ways of studying thermal reactions of solids. Problems arises, however, because many chemical reactions of solids, for instance the dehydration of hydrates, depend markedly on the experimental conditions - such as the nature of the atmosphere, shape of the container, the heating rate, etc. Such problems can be overcome by simultaneously performing XRD and DSC measurements on the same sample, and thus Rigaku/MSC offers the XRD-DSC for these special applications.
A presentation on this subject will be given at the Denver conference.

"We are excited about the opportunity to combine forces with Bruker AXS and strengthen our presence in the marketplace, particularly in proteomics." ( life sciences industry). The stock deal is worth $103.6 million
In connection with the merger, Bruker BioSciences has formed two operating subsidiaries, Bruker AXS Inc. and Bruker Daltonics Inc., into which it has transferred substantially all of the assets and liabilities, except cash, which formerly belonged to Bruker AXS and Bruker Daltonics, respectively.
As a result of the merger, Bruker BioSciences expects to offer a significantly broader technology base and product portfolio, as well as an increased global distribution, sales and service infrastructure, while retaining the entrepreneurial spirit and impressive growth of the two individual companies. Bruker BioSciences will have a more diversified customer base including pharmaceutical, diagnostics, biotech and other industrial companies, as well as other academic, medical school and governmental customers. "
Combined, the companies expect revenue of between $250 million and $260 million for 2003.
Its new name and Nasdaq symbol, BRKR will start trading on July 2

In 2003, SPECTRO presented the new 200T successor SPECTRO PHOENIX to the public for the first time. The SPECTRO PHOENIX now has a larger chamber for the sample material, comes with a network interface, and is even more robust than its predecessor. The system was also updated with reference to the newest analysis guidelines and is suitable for a wide range of applications.
Since its introduction to the market in 1991, the SPECTRO 200 / 200T has maintained its claim to the top of the market segment for compact bench top X-ray fluorescence analysis instruments. So that it stays there, the SPECTRO developers went to work. The result: a new instrument and a fitting new name.
The product brochure is available at our intranet website.


Net sales for the three months ended March 31, 2003 increased 22% to $29.0 million, compared to $23.8 million for the three months ended March 31, 2002. After elimination of favourable currency effects, revenue growth was 6%. Gross margins for the quarter continued to improve, increasing to 40.3%, compared to 38.3% for the first quarter of 2002.
Cash and cash equivalents totaled $48.6 million as of March 31, 2003. During the first quarter 2003, the Company paid off total debt of approximately $1.7 million.
Strong sales of X-ray fluorescence systems, including the S4 Pioneer, and improved after-market sales were the drivers of growth, although $3.6 million of positive currency affects and $1.6 million of revenues from last year’s acquisition of MAC Science Ltd aqlso played a significant role.


Energy Dispersive micro X-ray fluorescence spectrometer

The new Shimadzu series of Micro EDX instruments combine the resolution and flexibility of energy dispersive instruments with the speed and convenience of non dispersive instruments.
Microanalysis of electronic components, circuit boards, and foreign matter in foods was difficult with conventional fluorescence X-Ray spectrometers due to poor sensitivity at a small illuminated size and insufficient resolution even at full X-Ray intensity. However, the new Shimadzu series of Micro EDX spectrometers achieves high sensitivity and high resolution analysis of such samples down to a minimum measured diameter of 50 microns.
