WELCOME

The palpable tension of the NASA engineers during the successful live landing of Mars Perseverance Rover a few weeks ago caught the imagination of many. Unsurprisingly so, considering the amount of dedication required to plan, design, build and test such a piece of sophisticated equipment that will eventually provide scientists with valuable information on our neighboring planet.


These extreme feats of engineering and technology not only draw on scientific research already available from planet Earth’s scientific community, but also pave the way for new advancements. Extreme atmospheric and gravitational conditions and the payload limitations of the transport vehicle (ATLAS V) mean that the functional instruments on the Rover must be of unique design. Rigaku provides analytical instruments to support research into much of the equipment you might find on a Mars Rover, including solar panels, semiconductor chips, sensors and optics.


In fact, the Perseverance is equipped with an X-ray fluorescence spectrometer called PIXL, not unlike Rigaku’s Supermini200, to “seek changes in textures and chemicals in Martian rocks and soil left behind by any ancient microbial life.” It is very compact, about the size of a lunchbox, weighing in at 10 pounds. Miniaturization often brings advantages such as increased data storage and reduced power consumption, all factors that technology manufacturers strive to achieve when designing new products.

 

UPCOMING RIGAKU EVENTS

X-ray Computed Tomography Virtual Workshop
April 14, 1 PM | CDT

Join us for a live demonstration of X-ray Computed Tomography (CT) measurements using a high-resolution X-ray microscope. The audience will participate in selecting scanning conditions and compare different results. We will discuss how to optimize various parameters, such as X-ray energy, resolution, scan time and sample preparation. We also encourage the participants to ask questions about the challenges they face with their CT measurements and we will discuss them together.

Powder X-ray Diffraction Basic Course
Second Installment: Selection of Equipment Configuration to Obtain High-quality Data

By Masashi Omori, Rigaku Corporation


It is necessary to obtain high-quality data for highly accurate analysis. The characteristics of high-quality data may be high intensity, high resolution, high P/B (peak-to-background ratio), and high S/N (signal-to-noise ratio). Deciding which features are important depends on the purpose of analysis. Therefore, we need to consider measurement conditions after determining the purpose of analysis. Some combinations of sample types and optical systems prevent the desired results from being obtained. Therefore, it is necessary to select the optical systems according to the kinds of samples.

Sulfur Analysis in Petroleum Products by WDXRF According to ASTM D2622-16
Rigaku Corporation


Crude oil contains sulfur in concentration from 0.5 mass% to 5.0 mass% typically, and control of the level of sulfur in refinery intermediates and final products is critical in a refinery. Sulfur in petroleum-based fuels causes atmospheric pollution; therefore, sulfur content in fuels, especially in automobile fuels, is strictly controlled. Sulfur also causes damage to facilities such as catalysts in refinery processes. Therefore, control of sulfur content is very important in the petroleum industry from the standpoints of both environment and production cost.

Applications of the Two-dimensional Detector HyPix-3000 in X-ray Diffractometry
Rigaku Corporation


Various types of detectors have previously been used in X-ray diffractometers. Scintillation counters (SC) have been used as zero-dimensional (0D) detectors, position-sensitive proportional counters (PSPC) and semiconductor detectors as one-dimensional (1D) detectors, and devices such as imaging plates (IP) and CCD detectors as two-dimensional (2D) detectors. IP and CCD detectors are 2D detectors still in use today, but they have problems such as slow read-out speed and narrow dynamic range, and thus their applications are limited. The HyPix-3000 hybrid multi-dimensional pixel detector is a 2D detector with the following features not available with IP or CCD detectors.
