HPLC Principles and parameters | KNAUER

Principle of HPLC. The separation principle of HPLC is based on the distribution of the analyte (sample) between a mobile phase (eluent) and a stationary phase (packing material of the column). Depending on the chemical structure of the analyte, the molecules are retarded while passing the stationary phase.

Reversed Phase Chromatography

How Do Cell Phones Work? – Pong Pulse

 · Cell phones transmit radio waves in all directions. The waves can be absorbed and reflected by surrounding objects before they reach the nearest cell tower. For example, when the phone is placed next to your head during a call, a significant portion (over half in many cases) of the emitted energy is absorbed into your head and body.

Pitot Tube Working Principle

 · Because the simple Pitot tube (Above Figure ) only samples a single point, and, because the flow profile of the fluid (and hence velocity profile) varies across the pipe, accurate placement of the nozzle is critical. To avoid this type of problems we are using averaging pitot tubes. Note that a square root relationship exists between velocity and pressure drop (see Below Equation).
