| TAILING FACTOR: a
measure of how much a band deviates from being perfectly
bell-shaped or symmetrical; calculated as shown here. See
also ASYMMETRY FACTOR. In most cases, the ASYMMETRY
FACTOR and TAILING FACTOR for a peak will be of similar
magnitude, but only rarely are they exactly equal.

The Tailing Factor is one way of describing tailing

MOBILE PHASE: a mobile

three solvents (e.g., methanol, water and acetonitrile.)
Also called TERNARY MOBILE PHASE.

CHROMATOGRAM: a chromatogram from the column
manufacturer that usually accompanies a new column,
showing the separation of a particular sample under some
set of experimental conditions; the test chromatogram
shows how well the column performs under standard (and
generally ideal) conditions.

| TETRAHYDROFURAN
(THF):
one of three organic solvents commonly used (with water) to
prepare reversed-phase mobile phases (see also ACETONITRILE and METHANOL).

| TMS or
TRIMETHYLSILYL: a kind of bonded phase used for reversed-phase chromatography.

| TROUBLESHOOTING:
refers to locating the cause of problems with the LC
