Glycolic acid, the predominant metabolite, has been measured by HPLC and gas chromatography, by a colorimetric method, and by isotachophoresis [27,52-54].
RLPs can also be separated according to charge by agarose gel electrophoresis (double pre-[beta] lipoproteins) or capillary isotachophoresis, or according to their size as midband lipoproteins (between VLDL and LDL bands) by 3% polyacrylamide or gradient gel electrophoresis.
In research, the determination of apolipoproteins encompasses their measurement in cell culture supernatants (4), lipoprotein subfractions separated by ultracentrifugation (5), isotachophoresis (6), immunoaffinity chromatography (7), or size-exclusion chromatography (8).

Determination of glycyrrhizin in liqueurs by on-line coupled capillary isotachophoresis with capillary zone electrophoresis.
The uniting theme of the projects is the use of microfluidics and isotachophoresis (ITP) to enable precise transport, focusing, and control of samples within micron-sized channels.
Several reports have described microscale preconcentration methods (30) and a number of preconcentration techniques, such as field-amplified sample stacking (31), temperature gradient focusing (32), and isotachophoresis (ITP) [4] (33).
