Eluant peaks are detected by UV absorption at 262 nm.
The eluant was evaporated in a centrifugal vacuum concentrator to dryness and reconstituted in 300 [micro]L of 0.
Distilled water was the initial eluant, and it eluted the nucleosides; then discontinuous increments of NaCl concentrations were applied to elute the nucleotides.

Eluant was directed into an electrospray mass spectrometer (API 365; Applied Biosystems, Foster City, CA).
The eluant was tetrahydrofuran flowing at 1 mL/min and at temperature of 35[degrees]C.
This means an entirely new eluant system must be developed that is completely compatible with the mass spectrometry.
IEC, effect of eluant concentration, and analysis of elution behavior were also carried out to understand the IECs of the AECFs.
Despite apparent bead loss into the eluant during the 5th run (suggesting column failure), the depletion efficiency was 99% for that run.
4]) and concentrated to give a thick liquid which on silica gel chromatography using hexane as the eluant gave tetraallyl compound 4 as a colourless liquid (21 g, 47% based on the amount of diamine I present after reaction with ethyl formate).
The polyprenols are then purified by several stages of column chromatography using silica gel and eluant systems of staged polarity.
