A Sample cross from LITech is used for the homogeneous division and mixing of bulk or granular materials – especially in sample preparation for laboratory analysis. Only when the sub-sample accurately reflects the original material can meaningful results be achieved. Our sample cross divides smaller quantities of powder, granules, and bulk material samples.
The use of a sample cross ensures high representativeness and homogeneity of the sample, especially with inhomogeneous materials. This enables reliable and meaningful analysis results, as a uniform distribution of properties within the sample is ensured.
A sample cross is used for the homogeneous division and mixing of bulk materials, powders, or granular materials. It ensures that the sample taken represents the entire sample as accurately as possible – a fundamental prerequisite for reliable laboratory analyses.
The use of a sample cross ensures a uniform distribution of the properties in the sample. This ensures representativeness and homogeneity, which is crucial for quality assurance according to LAGA PN 98.
First, several individual samples are taken from different areas of the total sample. These are arranged in a cross shape on a clean surface, mixed together, and tapered in the middle. This creates a representative mixed sample that is used for analysis.
Sample crosses are used in many industries – including:
Before application, the LAGA PN 98 specifications regarding sample number and sample size must be considered. Determining the maximum grain size is particularly important, as this influences the required sample volume. Careful planning is crucial for a representative result.
