Powdered Samples And Pellet Samples
Powder and pellet samples are placed in the sample cell and supported with polypropylene film.
ALTRACE - Features
Energy Dispersive X-ray Fluorescence Spectrometer
Unparalleled Sensitivity
With Shimadzu’s combination of optical system design and proprietary high-speed signal processing, ALTRACE reaches the highest detection sensitivity compared to Shimadzu’s general-purpose systems (EDX-7200).
Unparalleled Sensitivity that Goes Beyond Typical Measurement Needs
Comparison of detection limit between conventional
equipment (EDX-7200) and ALTRACE
-
The combination of optical system that optimally arranges high-power X-ray tube and high-sensitivity detector, and high-speed signal processing has achieved high detection efficiency.
-
-
In the analysis of aqueous solution samples, the detection limit for all elements have been improved compared to the conventional equipment (EDX-7200).
-
-
It can be used effectively for the analysis of low-concentration samples and the automatic analysis of multiple samples requiring shorter measurement time.
Implements batch element analysis across a wide range from the sub ppm level to the % level
Automatic Filter Exchange Improves Sensitivity
Background removal is facilitated by a primary X-ray filter, thereby improving S/N ratio.
For trace-level analysis, where background is not negligible, filters are particularly advantageous.
ALTRACE is equipped with 6 primary filters (8 types, including open and attenuator), which can be exchanged autonomously by the software.
| Effective Energy (keV) | Example of Applicable Elements | |
|---|---|---|
| Filter #1 | 14 to 38 | Mo,Rh,Pd,Ag,Cd,Sn,Sb |
| Filter #2 | 2 to 4 | S,Cl |
| Filter #3 | 5 to 10 | r,Mn,Fe,Co,Ni |
| Filter #4 | 9 to 10 | Hg |
| Filter #5 | 9 to 14 | As,Br,Zr,Hg,Pb,Bi |
| Filter #5 | 4 to 5 | Ti,V |
Escape From Complicated Pretreatment
Liquids and powders can be directly measured by simply placing them as is in the sample cell. EDX is a non-destructive technique; therefore, the same sample can be measured for both simple screening and precision analysis. To date, previous EDX systems could not measure concentrations on the order of 0.1 ppm. With ALTRACE, this level is now detectable. It is now possible to obtain sub-ppm level detection, without the need for chemical pretreatment.
Simple Screening In Combination With Precision Analysis
When performing quantitative analysis by specifying elements, once a calibration curve is created, there is no need to recreate the calibration curve for each measurement.
In addition, ALTRACE is suitable for simple screening analysis, since qualitative and quantitative analysis using the fundamental-parameter (FP) method can be performed without specifying elements
Solids, Powders And Liquids Can Be Measured As Is
With ALTRACE, samples are placed into a dedicated sample cell. The sample is supported by a transparent X-ray film that is suitable for the sample.

Liquid Samples (Water Soluble And Oleaginous)
Aqueous solutions are poured into the sample cell and supported on a polypropylene film. Other liquids, such as organic solvents, can be measured by using an appropriate film.
High Throughput And Efficiency
Automatic Consecutive Analyses Of Up To 48 Samples
710mm wide main body is equipped with a multi-sample changer. The tray drawer system allows for safe sample replacement without having to access the inside of the instrument.
Analysis Can Be Paused And Reassigned, Increasing Flexibility
During analysis, ALTRACE can be paused, and new samples can be added and the analysis schedule adjusted accordingly. As such, there is no need to wait for analysis to be completed to start sample preparation.
