Sieve Analysis and Grading Curves

Sieve analysis is a method used to determine the particle size distribution of aggregate materials. This process involves the following steps: The required quantity of dried sample of aggregate is weighed. The weighed aggregates are sieved through a set of sieves with square openings arranged in descending order of aperture size, with the largest mesh on top (Column 1 of Table 1). The stack of sieves is shaken or vibrated to facilitate the sorting of particles by size. After sieving for a...

Electrical Penetration Graph (EPG) is a well-established technique for studying the feeding behavior of stylet-bearing insects. Here we show a new application of EPG as a non-invasive tool for the acquisition of intracellular electrophysiology recordings of sieve elements (SEs), the cells that form the phloem vasculature in plants.

Sieving Fruit Pulp to Detect Immature Tephritid Fruit Flies in the Field

Increasing the detection of immature tephritid fruit flies in the field can trigger timely efforts to eliminate populations of these destructive pests. Detecting late instar larvae is faster and more accurate when mushing host fruit in a bag and passing the pulp through a series of sieves than hand cutting and visual inspection.
FAQs
Particle classification depends on the relationship between opening size and particle dimensions. In a stacked screen arrangement, larger openings are placed above smaller ones, so agitation progressively sorts material into size classes. The retained fraction on each screen records where particles were stopped, allowing researchers to compare the composition of heterogeneous soil, sediment, compost, or other particulate samples.
Consistent drying and disaggregation are important because moisture and clumping can alter how particles move through the screens. A sample that remains damp or aggregated may behave as larger units rather than as separate particles, changing the apparent distribution. Keeping these preparation conditions consistent makes results more reproducible and strengthens comparisons among environmental samples.
Agitation helps expose particles to the openings repeatedly, enabling smaller particles to pass while coarser material remains retained. Its role is therefore linked to separation efficiency: insufficient or inconsistent movement can change which particles pass through each mesh. Maintaining comparable shaking or agitation conditions supports reliable size classification across environmental samples.
A typical Sieving Procedure begins with sample drying and disaggregation. The prepared material is then passed through one or more mesh screens, commonly arranged from larger to smaller openings. Shaking or another form of agitation allows fine particles to pass while coarser fractions are retained. The separated fractions can then support particle-size distribution and composition measurements.
Environmental researchers can use the procedure when they need to characterize soil, sediment, compost, or other particulate material by size. The resulting fractions support particle-size distribution measurements and can help examine how contaminants are associated with particular portions of a sample. This makes sieving useful during environmental material characterization, rather than only as a physical separation step.
Sieving results can help connect particle-size structure with environmental behavior. Size information supports interpretation of how soil and sediment characteristics relate to transport and erosion, while also contributing to assessments of contaminant associations and habitat quality. Because these relationships depend on the sample's physical structure, reproducible preparation and screening are important when comparing materials.
