Ultim Max
In situ

Extreme electronics allow high throughput. This allows it to keep counting X-rays even at high temperatures with an intense IR radiation background.

Ultim Max
Sensitivity

Extreme electronics have very low noise. This allows accurate identification and characterisation of X-ray lines down to 72eV.

AZtecTEM
M2T

Direct measurement of specimen thickness across the sample using EDS. All from one simple single standard measurement.

Speed & Sensitivity

REAL-TIME CHEMICAL MAPPING

EVEN AT ELEVATED TEMPERATURES

An increase in both solid angle and take off angle combined with windowless detection and Extreme electronics has led to uncompromised X-ray sensitivity. This means that the Ultim Max can now detect lower X-ray energies than ever before. The combination of Extreme electronics with the X4 pulse processor also allows for in situ EDS mapping and quantification at elevated temperatures > 800­°C.

CALCULATE SAMPLE THICKNESS

Our easy to use quant routine allows for quantification by mass thickness. This allows you to use EDS alone to weigh nanoparticles with atomic accuracy. Using this method, it is now possible to calculate the thickness of a specimen and further understand the contrast in your images.

Application Notes

Simultaneous EDS and EELS

EDS is a mature technique that can be used for most specimens. EELS is more suitable for thin samples where the thickness is less than the inelastic mean free path of electrons in the material. Simultaneous acquisition of both signals is a powerful tool for materials analysis.

Semiconductor Mapping in the TEM - Solving peak overlaps in real-time

Elemental analysis of semiconductors is typically difficult due to strong overlaps of X-ray lines between commonly used elements and low concentrations of dopants. This brief shows how AZtecTEM solves these overlaps to achieve an accurate elemental analysis.
