WHC’s suppliers are carefully qualified, and receive a detailed
specification sheet for each product that we import. Pre-shipment
samples are tested for compliance to spec before purchase, and compliance
is confirmed by our Lab once the product is received into our warehouse.
The following are in-house tests that our
Lab performs:
- Product Identity is verified through organoleptic testing and
comparison to retained approved samples from WHC’s Sample
Library.
- Quality and potency is determined.
- Cleanliness is tested.
- Particle size is measured.
- A Metal/Magnet Test is performed.
- Bulk Density Testing as specified.
- Loss on Drying is quantified.
- Microbial Counts are verified.
When our customers require more detailed macro and microbiological
testing such as Thin Layer Chromatography or Fourier Transform Infrared
Spectroscopy, we utilize qualified independent Labs such as Silliker,
Certified Labs, Great Basin Labs and Covance.
