A Skoltech professor and his Chinese colleagues have revised a key chemical concept, electronegativity, and determined this characteristic for all elements under varying pressures. The revamped notion ...

High Pressure Liquid Chromatography (HPLC) is an important separation technique for compounds of low or no volatility thus it makes a nice complimentary procedure to GC. Like GC and all other ...

The pressure caused by a column of liquid can be calculated using the equation: pressure = height of column × density of the liquid × gravitational field strength The density of water is 1,000 kg/m 3.

A pressure transmitter can be used to establish the liquid level in a river, tank, well, or other body of liquid. The pressure at the bottom of a liquid filled container is directly connected to the ...
