SX-01020LVC / SX-01030LVC Low Vacuum Capsule for analyzing liquid samples

Helium-free light elements analysis is achieved in liquid!


Recent serious problem of a reduced supply of helium has led to an increased demand of alternative methods for X-ray fluorescence spectrometers which perform light-elements analysis in liquid with the use of helium.
The Low Vacuum Capsule enables samples to preserve its liquid state in a sample chamber under vacuum, thus allowing for helium-free light elements analysis in liquid.

Measurement example

Mineral measurement in food: Trace volumes of Mg can be detected and quantified.

Configuration of the Low Vacuum Capsule

The Low Vacuum Capsule enables analysis of a sample in liquid while suppressing sample vaporization and maintaining the pressure which does not cause a break of the sample analyzing film, by setting the pressure of the liquid sample cup to a low vacuum.
