Chromatographic

Following this characterization, chemical (chromatographic) processes were used to isolate the alkaloid analogues.

Several new technologies related to chromatographic devices and consumables, have emerged recently in the market.

A curium compound is then selectively extracted using multi-step chromatographic and centrifugation techniques with an appropriate reagent.

Chromatographic methods specific for amphetamine are employed to prevent false positive results.

Gas chromatographic separation is always carried out in a column, which is typically "packed" or "capillary".

However, if a direct "catcher" gold foil is used, the process is complicated by the need to separate out the gold using anion-exchange chromatography before isolating the nobelium by elution from chromatographic extraction columns using HDEHP.

I call such a preparation a "chromatogram" and the corresponding method, the "chromatographic method".

Many commercial opiate screening tests cross-react appreciably with oxycodone and its metabolites, but chromatographic techniques can easily distinguish oxycodone from other opiates.

More comprehensive tests include water determination according to the Karl Fischer method and gas chromatographic determination of byproducts.

Most commercial cocaine immunoassay screening tests cross-react appreciably with the major cocaine metabolites, but chromatographic techniques can easily distinguish and separately measure each of these substances.

Osamu Shirota and colleagues reported a method for the large-scale synthesis of psilocybin without chromatographic purification in 2003.

Production is chiefly through chromatographic separation, using techniques such as the "simulated moving bed".

Seaborg, p. 47 Separation Elution curves: chromatographic separation of Fm(100), Es(99), Cf, Bk, Cm and Am Separation procedure of einsteinium depends on the synthesis method.

Techniques by chromatographic bed shape Column chromatography details Column chromatography is a separation technique in which the stationary bed is within a tube.

The chromatographic separation behavior was then unknown for the element 97, but was anticipated by analogy with terbium (see elution curves).
