Chromatography - NJIT SOS

The solid or coated support is packed into a tube, with the gas flowing through it. Separation depends on the relative partial pressures of the sample components above the stationary phase. Liquid chromatography uses similar packed tubular columns and usually a pump to force a liquid mobile phase through the column.

TIMS - Washington University in St. Louis

Density Separation. Density separation is based on the fact that different minerals have different densities. Thus, if a mixture of minerals with different densities can be placed in a liquid with an intermediate density, the grains with densities less than that of the liquid will float and grains with densities greater than the liquid will sink.

Centrifuge - Wikipedia

A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a force perpendicular to the axis of spin (outward) that can be very strong. The centrifuge works using the sedimentation principle, where the centrifugal acceleration causes denser substances and particles to move outward in the radial direction.

Is gravity the same on all objects? - Quora

Furthermore, the situation is made far more complicated by the fact that the force of gravity is inversely proportional to the square of the separation between two objects. Since the distance can be ANYTHING, the force of gravity cannot possibly be the same on all objects. Say your mass is 100 kg.

Space Shuttle Solid Rocket Booster - Wikipedia

The Space Shuttle Solid Rocket Boosters (SRBs) were the first solid fuel motors to be used for primary propulsion on a vehicle used for human spaceflight and provided the majority of the Space Shuttle's thrust during the first two minutes of flight. After burnout, they were jettisoned and parachuted into the Atlantic Ocean where they were recovered, examined, refurbished, and reused.

Density Separation of Materials by Using Magnetic Fluids

Nonmagnetic materials of different densities are rapidly float/sink separated by an augmented lifting force produced in a magnetic fluid (liquid) by the effect of an external magnetic field.
