State-of-the-Art Testing

Kirkman's Products Are Tested Using State-of-the-Art Technologies

Kirkman's Ultra Tested® is done by highly equipped, state-of-the-art independent laboratories that have been selected carefully based on their excellent reputations for nutraceutical testing.

Kirkman® uses many laboratories for the specialized services they offer because no one lab could run all the assays we require.

Only the most advanced and accepted methods and procedures for the Ultra Tested® protocol are employed.  The laboratory equipment used is the most advanced state-of-the-art equipment available, including mass spectrometers for heavy metal and pesticide testing contaminants with exacting precision up to parts per trillion.



Raw Material Identity

Raw material identity is verified using Near Infrared (NIP) Spectroscopy.  This equipment uses a material's absorbance characteristics in the NIR visibility spectrum to construct an absorbance graph typical of that particular material.
Heavy Metal Analysis

Heavy metal analyses of raw materials and finished products are performed by state-of-the-art ICP-Mass Spectrometer (ICP-MS) equipment that offers microanalysis of heavy metal contamination.  Results can be obtained in parts per billion on all materials and even parts per trillion under certain conditions.

This type of equipment is the only accepted and required type of laboratory equipment for complying with California's Proposition 65 heavy metal specifications.  Sample preparation for the ICP-MS is performed using advanced technology microwave digestion.

Allergy Testing

The allergy testing of Kirkman's products is done by way of enzyme-linked immunosorbent assay (ELISA) methodology, which is sensitive down to specific parts per million depending on the allergen.  Casein, gluten, soy and peanut allergens are continually monitored in all of Kirkman's products.
Label Claim Verifications and Stability Testing
Label claim verifications and ongoing stabilty studies of Kirkman's products are performed using Food and Drug Administration (FDA), United States Pharmacopeia (USP), Food Chemical Codex or equivalent Association of Analytical Chemists (AAC) methodology.  In the case of contaminants regulated separately by the State of California under Proposition 65, Kirkman® follows California's recommended testing procedures, which usually are even more stringent than the FDA's or USP's.
Microbiological Testing (Bacteria, Yeast, Mold)

Kirkman® also monitors raw materials and finsihed products for the presence of microbiological contamination, yeast and mold growth.  Stringent limits are in place to monitor aerobic bacterial plate counts, yeast and mold counts, and the continuous absence of problematic bacteria including E. coli, Salmonella, Staphylococcus aureus and Listeria.  Testing methods utilized for this microbiological testing are derived from the FEDA's Bacteriological Analytical Manual, the USP or the AOAC.
Kirkman's Quality Assurance

Kirkman® has a Quality Assurance department that is entirely devoted to ensuring that the laboratories we use are well qualified; use the most current and best testing procedures; and test with the most up-to-date equipment for effective, accurate results.
