How it works

The HPLC tests separate the named compounds and measure them against reference standards.

Tests offered

Hydroxycitric acid and hydroxycitric acid lactone content by HPLC

Measures hydroxycitric acid and its lactone, for example in Garcinia materials, by HPLC and reports each. Tell us whether your specification states them separately or as a total.

4-Hydroxyisoleucine content in fenugreek seed extract by HPLC

Measures 4-hydroxyisoleucine, an amino acid of fenugreek seed, in fenugreek seed extract by HPLC.

Raspberry ketone content by HPLC

Measures raspberry ketone, 4-(4-hydroxyphenyl)butan-2-one, by HPLC as a single compound.

Nitrate content in red spinach by HPLC

Measures nitrate in red spinach (Amaranthus) materials by HPLC, reported as your specification states.
