Quality Assurance Section at NPRC
The Quality Assurance section at NPRC boasts the following advanced analytical instruments
for chemical analysis of plant materials:
- Liquid Chromatograph Tandem Mass Spectrometer (LC-MS/MS): For detection,
identification and quantification of both primary and secondary metabolites in herbal
materials. Furthermore, the LC-MS/MS is also used for the determination of pesticide
residues and natural toxins e.g aflatoxins, ochratoxins and fumonisins in plant materials,
water and biologicals; - Gas Chromatograph Mass Spectrometer (GC-MS): For analysis of essential oils and
fragrances as well as other primary metabolites in herbal plants; - High Performance Thin Layer Chromatography (HPTLC) Densitometer: For
visualization of screened herbal extracts for the purposes of identification and
fingerprinting of their constituents; - Portable X-Ray Fluorescence (XRF) spectrometer: For determining the elemental
composition of plants, soil and fluids; - Ultra Violet – Visible (UV-Vis) Spectrophotometer: For characterizing chemical
compounds in plants and other materials based on their ability to absorb UV and Visible
radiation; - Fourier Transform Infra-Red (FTIR) Spectrometer with Attenuated Total
Reflectance (ATR) technology: For creating fingerprints of plant extracts as well as
rapid determination of chemical functional groups in isolated plant compounds.
