Standardized Volumetric Flow
Flow meters operate on principle of interpreting fluid flow based on velocity of fluid. Examples are Magnetic, ultrasonic, turbine, vortex flow meters
Multi Column Gas Chromatograph
Improving Chromatograph Analysis Time with Multi Column Gas Chromatograph The “Achilles heel” of chromatography is the extraordinary length of time required
Chromatograph Sample Valves
Arguably, the component most critical to measurement accuracy in a gas chromatograph is the sample valve. Its purpose is to
Industrial Applications of Chromatographs
Since process chromatographs have the ability to independently analyze the quantities of multiple species within a chemical sample, these instruments
Measuring Gases Concentration in Chromatograph
While time is the variable used by a chromatograph to discriminate between different species (types) of chemical compounds, the concentration
Thermal Conductivity Detector (TCD) Principle
Thermal conductivity detectors work on the principle of heat transfer by convection (gas cooling). Here, the assumption is that sample
Flame Ionization Detector (FID) Principle
Several different detector designs exist for process gas chromatographs. The two most common are the flame ionization detector (FID) and
Online Gas Chromatograph Principle
The most common type of chromatography used in continuous process analysis is the gas chromatograph (abbreviated “GC”), so named because
Thin-Layer Chromatography : Manual Method
One of the manual chromatography methods taught to beginning chemists is thin-layer chromatography, also known as TLC. An illustrated sequence
What is Chromatography ?
Imagine a major marathon race, where hundreds of runners gather in one place to compete. When the starting gun is
