Application of Laboratory Hydraulic Press in Spectroscopy

Creating KBr Pellets for FTIR

When a mixed sample and KBr powder is compressed inside a die using a hydraulic press, its uniform force will produce a solid pellet which is mostly transparent to infrared light; but also contains a dilute quantity of sample, which is within the detection range of an FTIR instrument. The press applies an evenly distributed pressure over the sample, which transforms refractive material into transparent films that can be used for spectroscopic analysis. With the right press, this process can be completed in a few minutes.

FTIR is a type of spectroscopy that uses infrared light to study the properties of matter. In order to study the molecular structure of a powder sample, it first needs to be diluted in a transparent material – which is where the hydraulic press comes in. The hydraulic press is essential to create KBr (potassium bromide) pellets for FTIR analysis. The press ensures that the sample is uniformly compressed, resulting in a transparent pellet that can be easily analyzed using an FTIR instrument.

Application in XRF Spectroscopy

Similarly, XRF spectroscopy is an analytical technique used to determine the elemental composition of materials. By producing general sample pellets in a hydraulic press, the integrity of a sample can be maintained throughout the XRF process. By squeezing the sample between two pressure plates at high pressure, a hydraulic press ensures that the sample is completely compacted and ready for analysis.

XRF (X-ray fluorescence) spectroscopy is a non-destructive technique that uses X-rays to excite the atoms in a sample. This excitation causes the atoms to emit characteristic X-ray fluorescence, which can be measured and used to identify the elements present in the sample. To perform XRF analysis, the sample needs to be in pellet form. A hydraulic press is used to compress the sample into a solid pellet, ensuring that it is fully compacted and ready for analysis.

Powder Compaction for Composite Material Study

In addition to creating KBr pellets for FTIR and general sample pellets for XRF, a laboratory hydraulic press is also useful for other applications in spectroscopy. For example, it can be used to test the strength and durability of materials, investigate the effects of high pressure on different substances, and create pellets for sample analysis.

Laboratory hydraulic presses are smaller versions of industrial hydraulic presses that are specifically designed for research and testing purposes. They offer more precision and control, allowing researchers to apply the required load for sample preparation. The use of a laboratory hydraulic press ensures reproducible load for pressing high-quality pellets suitable for quantitative studies.

Overall, the application of a laboratory hydraulic press in spectroscopy, particularly in creating KBr pellets for FTIR and general sample pellets for XRF, is essential for sample preparation. It allows for the uniform compression of samples, ensuring accurate and reliable spectroscopic analysis.
