HPLC Lab Test is the Only One Method to Determine Pure and Real Hoodia Gordonii

The lab test or lab assay is the document that shows if hoodia into a pill is real and pure hoodia gordonii 100% and no other. Such test is usually performed under a High-performance liquid chromatography (HPLC).

High-performance liquid chromatography (HPLC) is a form of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by injecting a plug of the sample mixture onto the column.

The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase. Solvents must be degassed to eliminate formation of bubbles.

The pumps provide a steady high pressure with no pulsating, and can be programmed to vary the composition of the solvent during the course of the separation.

Typical detectors rely on a change in refractive index, UV-VIS absorption, or fluorescence after excitation with a suitable wavelength.

HPLC test is one of the most accurate ways to determine the total content of elements for any plant or herb. Check our HPLC assay to see that we offer really pure hoodia gordonii.
