History Chromatography dates to 1903 in the work of the Russian scientist, Mikhail Semenovich Tswett, who separated plant pigments via liquid column chromatography. German physical chemist Erika Cremer in 1947 together with Austrian graduate student Fritz Prior developed the theoretical foundations of GC and built the first liquid-gas chromatograph, but her work was deemed irrelevant and was
TGIC Features. · Fully-automated operation with no manual solvent handling. Integrated vial solvent filling, sample dissolution, and in-line filtration. · Fast analysis time of around 2-3 hours including sample dissolution. · The dissolution time can be programmed individually for each vial, therefore, thermal degradation is minimized.
The LC-2030C NT is an integrated high-performance liquid chromatography system which prioritizes easy-to-use features for a smooth analysis experience. The intuitive touch-screen interface and stable column performance over many continuous injections ensure reliable data every time, whether you are an HPLC beginner or an expert.

The source vial, destination vial and capillary are filled with an electrolyte such as an aqueous buffer solution. The capillary is packed with stationary phase. To introduce the sample, the capillary inlet is placed into a vial containing the sample and then returned to the source vial (sample is introduced into the capillary via capillary action, pressure, or siphoning).

A simple liquid chromatography–quadrupole-time-of-flight–mass spectrometric assay (LC-TOF-MS/MS) has been developed for the evaluation of metabolism and pharmacokinetic (PK) characteristics of monomethyl auristatin F (MMAF) in rat, which is being used as a payload for antibody-drug conjugates. LC-TOF-MS/MS method was qualified for the quantification of MMAF in rat plasma.
For a given sample, four initial experiments are carried out at two different temperatures, using either isocratic or (better) gradient elution. If isocratic experiments are chosen for computer simulation, it is necessary to select appropriate values of % B for these initial runs.
