Solid Phase Extraction (SPE)
Solid Phase Extraction (SPE) Solid phase extraction (SPE) is a technique designed for rapid, selective sample preparation and purification prior to the chromatographic analysis (e.g. HPLC, GC, TLC). In SPE, one or more analytes from a liquid sample are isolated by extracting, partitioning, and/or adsorbing onto a solid stationary phase.

Processes of Mechanical Weathering
Sheet joints become surfaces along which curved pieces of rock break loose, exposing a new surface. This process is called exfoliation; large rounded landforms (usually intrusive rocks) that result from this process are called exfoliation domes. Examples of exfoliation domes are Stone Mountain, Georgia, and Half Dome in Yosemite National Park.

The Inside Story: What Is Quartz and How Is It Made?
The result is a slab of non-porous engineered stone that can either resemble granite or marble or contain such wow factors as colored glass inserts, mirrored pieces, or even semi-precious stones. Stellar Gray Quartz. The appeal of this man-made stone mix is that it is scratch and chip resistant, non-porous, and offers unlimited colors and designs.
Quarrying | Process and Equipment | Applications | Epiroc US
Quarrying is used mainly in the production of construction and building materials, such as solid stone or crushed rock for aggregates, or for raw materials for processes such as cement manufacture. As a technique, quarrying is normally only used where raw materials of adequate quality and size cannot be obtained economically by other means.
Gravel Size Chart, Crushed Stone And Rock Sizes, Uses, Grades
Crushed Stone #10 (Stone dust or screenings): Usually 1/8″ Wide or Smaller. Crushed stone number 10 is the finest grade and is often referred to as dust or rock/gravel screenings. Resembling coarse sand, #10 is produced as a byproduct of the crushing process and has many uses in the construction and landscaping industries:
