In 1901, he presented an adsorption chromatography method for separating plant pigments with petroleum ether in a narrow glass tube filled with calcium carbonate. Tsvet published his work in 1903 and tested 126 different powdered adsorbents. He was the first to use the term “ch...
Screening Gradient – Powerful for Method Development Interpretation: For a reversed phase LC column where A is water and B is organic, this first run shows sample constituents that are all polar. So, the separation is poor because the substances experience little partitioning on the stationary pha...

Particular care must be taken when using an aspirator reducing pressure method, as the eluent composition changes depending on the time spent on pressure reduction and which may affect the reproducibility of analysis. The online degassing methods include the use of helium gas purge and degasser. A...
Hence, coupling µPAC with mass spectrometric detection is the preferred detection method (see below). 5.4. Phase ratio The phase ratio is defined as the stationary phase volume and mobile phase volume quotient for particle-packed HPLC columns. The stationary phase volume is the stagnant solvent...
