RETSCH Sample Preparation XRD-Mill McCrone Set
The 224600001 XRD-Mill McCrone Sample Preparation Set is a complete set to prepare your samples for X-rays and X-ray diffraction (XRD) analysis. This set includes a stainless steel percussion mortar, 10 corundum grinding elements, 1 sieve 500 and 1 brush. All you need for perfect results in your lab.
The stainless steel percussion mortar is robust and long-lasting. Corrosion resistant material ensures that your samples are not damaged during the preparation process and you get accurate and reproducible results every time.
The 10 corundum grinding elements are excellent grinding tools to reduce various sample materials to a fine powder. They are designed to withstand high mechanical stress and are optimal and long lasting. With many applications they are suitable for various sample types and give you flexibility in your lab procedures.
The 500 sieve in this set makes your sample preparation even more efficient. The sieve separates the fine particles from the ground sample and you collect only the desired particle size fraction for further analysis. This is precision for your XRD experiments.
To complete this sample preparation set a brush is included to clean the mortar and grinding elements. The brush removes any remaining particles and prevents cross contamination and gives you the highest accuracy and reproducibility in your analysis.
The 224600001 XRD-Mill McCrone Sample Preparation Set is the perfect tool for scientists and researchers who need a complete sample preparation system for their XRD analysis. Robust, good grinding, precise particle size separation and easy to clean brush. Streamline your lab workflow and improve your research with RETSCH. Get perfect sample preparation for XRD analysis.
Sample preparation is key for good XRD data. The goal of sample preparation is to get a sample that is representative of the material and gives you accurate and reproducible results. This involves several steps: selecting the right sample preparation method, grinding the sample to a fine powder and mounting the sample in a sample holder. By grinding and mounting the sample uniform and proper you get precise and reproducible results and get insight in the material properties.
Product Components
The following components are used in XRD sample preparation:
-
Sample holder: A device to hold the sample during analysis. Sample holders can be made of stainless steel, aluminum or plastic and are necessary to keep the sample in position and orientation during X-ray diffraction.
-
Double sticky tape: A kind of adhesive tape to fix the sample to the sample holder. This keeps the sample in place and prevents any movement that could affect the analysis.
-
Glass slide: A flat and transparent slide to support the sample during analysis. Glass slides give a stable and smooth surface for the sample and gives consistent results.
-
Powder samples: Samples ground to a fine powder to get uniform and random crystallites. This is important to avoid preferred orientation and get accurate phase identification.
-
Tungsten carbide: A hard and wear resistant material used in some sample preparation tools like mortars and pestles. Tungsten carbide is perfect for grinding hard materials to a fine powder.
Solid Samples
Solid samples can be prepared for XRD analysis by:
-
Cutting: Cutting the sample to the right shape and size with a saw or other cutting tool. This step ensures the sample fits in the sample holder and the area of interest is accessible for analysis.
-
Grinding: Grinding the sample to a fine powder with a mortar and pestle or other grinding tool. Grinding is important to break the sample into uniform particles to get accurate and reproducible X-ray diffraction results.
-
Polishing: Polishing the sample to remove surface roughness with a polishing cloth or other polishing tool. A smooth sample surface is important to minimize scattering and get clear diffraction patterns.
Mounting and Fixing
Once the sample is prepared it has to be mounted and fixed in the sample holder. This can be done by:
-
Double sticky tape: Apply double sticky tape to the sample and fix it to the sample holder. This is quick and easy for powder samples.
-
Glass slide: Place the sample on a glass slide and fix it to the sample holder. This gives a stable and smooth surface for the sample and gives consistent results.
-
Sample holder: Place the sample directly in the sample holder and fix it with a lid or other retaining device. This is often used for solid samples that are cut or polished to fit the holder.
Troubleshooting
Common problems that can occur during XRD sample preparation:
-
Preferred orientation: This happens when the crystallites in the sample are not randomly oriented and gives inaccurate results. To avoid this, make sure powder samples are properly ground and randomized.
-
Phase identification: This can be tricky if the sample is not prepared well and gives wrong phase identification. Grinding and mounting is important for accurate phase identification.
-
Sample surface: The sample surface can affect the XRD data so make sure the surface is smooth and flat. Polishing the sample can help achieve this.
-
Powder samples: Powder samples can have preferred orientation so make sure the powder is properly ground and randomized. This will give accurate and reproducible X-ray diffraction results.
-
XRD: XRD is affected by the sample preparation so make sure the sample is prepared well to get accurate and reliable results. Good sample preparation techniques like grinding to fine powder and smooth surface is important to get good data.
