Lab Testing

Mitra Science assures consistent quality by regularly performing a variety of tests and procedures to ensure the quality of the bulk botanical specimens we offer.

In addition to conducting the tests listed on this page on our products, we offer third party testing services on a contract basis. The following list represents a few of the most important tests we conduct:

Botanical Identification

  1. HPLC: Stands for High Pressure (Performance) Liquid Chromatography. This test provides verification of product identity as well as quantitative determination of active constituents when tested against a reference standard.
  2. GCMS: Stands for Gas Chromatography Mass Spectrometry. This test provides verification of product identity as well as quantitative determination of active constituents when tested against a reference standard.
  3. TLC: Stands for Thin Layer Chromatography. This test provides verification of product identity when tested against a reference standard.

Organoleptic

  1. Appearance: Samples of each product are evaluated based upon their general appearance and uniformity and are compared, to ensure conformance, to a known standard.
  2. Color: Used to identify products based upon conformance, of color, to a known standard.
  3. Aroma: Used to identify products based upon conformance, of aroma, to a known standard.

Physical Analyses

  1. Particle Size: A sieve analysis is used to measure the total particle size distribution of a prepared sample. Whether the product is in the form of a powder, cut and sifted, or tea bag cut, particle size analysis can help a customer judge whether a product is suitable for their application.
  2. Tapped Density: Measures the density of a prepared sample (g/ml). This test can help one discern packaging or encapsulation requirements.

Chemical Analyses

  1. Heavy Metals: This test measures metallic impurities in a prepared product sample. No product may exceed the tolerances that have been set for each specific metal.
  2. Pesticides: This test measures the amount of pesticide residue that a prepared sample contains. No product may exceed the tolerances that have been set for each specific pesticide.

Microbiological

  1. Total Aerobic Plate Count: This test allows for the detection and enumeration of aerobic microorganisms. This test gives an indication of the cleanliness of a product microbiologically.
  2. Yeast and Mold: This test allows for detection and enumeration of yeast and mold microorganisms. This test gives an indication of the cleanliness of a product microbiologically.
  3. Coliform: This test allows for detection and enumeration of Coliform.
  4. E. Coli: This test allows for detection and enumeration of E. Coli bacteria.
  5. Salmonella SPP.: This test allows for detection and enumeration of Salmonella Bacteria.

Please note that some of the above tests are only performed as needed and not on every item we process. For more information about a particular test or item, please contact us.
