In an industry filled with many splitter kinds, it's tough to know which one is appropriate for your individual needs. The sample division is a crucial part of sample testing and analysis. A sample splitter separates a representative sample from a large quantity while preserving its qualities.
Using the right splitter may drastically minimize variability in the laboratory. Check out our helpful tips so you can select the ideal splitter for your needs and get the job done error-free.
Consider material type first
Splitters are the best option for collecting representative samples of dry, flowable materials. When choosing the appropriate equipment, start by considering particle size, shape, density, and moisture content. In reality, particle size determines chute width.
A proper chute width is three times the biggest dimension of the largest particle. This guarantees that the two biggest particles in a sample may pass through the chute without becoming stuck (bridging).
Bridging causes the material to back up and be shoved into neighboring chutes, resulting in bias inaccuracy in the samples. In contrast, too-wide chutes may not allow for sufficient separation, resulting in less precise splits.
Review test specifications
When it comes to splitting standards, certain test techniques need a specified number of chutes or hopper capacity. For example, certain industries may demand a steeper chute angle to help in the separation of lower density particles such as coal or coke, while others may require a minimal number of chutes.
Other test techniques are less stringent, allowing for a variety of splitter configurations as long as the criteria are satisfied.
Determine size and capacity requirements
The fewer splits necessary to divide resources, the better. A splitter with insufficient capacity necessitates extra division, increasing the possibility of mistakes. Performing several splits takes more time and effort.
Standard test procedures may specify a weight or volume range for the final test specimen, or the size may be restricted only by the available space in the test chamber. The appropriate number of passes is determined by estimating what proportion of the original sample remains in the final specimen.
If the original sample has a volume of several cubic feet and the test only requires a cup, a big splitter and many splitting passes are needed. As the size of the sample decreases, an additional, smaller splitter may be necessary to maintain accuracy.
Get familiar with important features
When it comes to splitters, adaptability is key. Consider which qualities are most essential to you. Here are some more features that will improve the efficiency of your sample operation.
Hoppers with gate release feature
This is the best function available for a sample splitter since it keeps all materials in the hopper until they are evenly dispersed and balanced. The gate-release hopper eliminates human error caused by uneven material pouring into an open hopper and flowing through only a section of the available chutes.
Material poured unevenly into an open hopper introduces sample bias.
Adjustable chute bars
This is crucial for a user who has samples with different maximum particle sizes. Adjustable chute bars allow chute lengths to be altered for a variety of materials, saving money and floor space over numerous units.
Adjustable chute bars can be optimized for different materials.
We recommend the "Large Capacity Sample Splitter" with gate release hoppers and adjustable width chutes for maximum versatility, adaptability, and user control.
This splitter line features a series of precision-machined metal bars that allow you to change the width of the chute and properly distribute material into sample pans. This innovative design allows the chute opening size to be instantly adjusted to the ideal width of three times the greatest particle size.
Splitter materials
For applications involving food-grade or reactive compounds, sampling equipment should have non-contaminating touch surfaces.
