GSN’s ongoing commitment to superior quality is backed up by rigorous analysis of our products in our own in-house testing laboratories.

The Quality Control/Analytical Development Department of GSN consists of a highly trained staff of 15 degreed chemists under the supervision of our resident Ph.D.

The department performs testing and inspection pertaining to the approval and release of all incoming raw materials and finished products. We also have the ability to develop and validate new test methods, even for exotic herbal ingredients.

Laboratory equipment and capabilities include:

• Fourier Transform Infrared (FT-IR) and Near Infrared (N-IR) Spectrometers — for positive identification fingerprinting of incoming raw materials.
• High Performance Liquid Chromatography (HPLC) — for accurate quantitative analysis of vitamins, amino acids and botanical actives. Our 7 Waters HPLC Instruments are all interfaced to a Millennium 32 Client/Server System for seamless data integration.
• Perkin-Elmer Inductively Coupled Plasma Emission Spectrometer (ICP) — for precise analysis of nutrient minerals and heavy metals.
• Beckman UV/Visible Spectrometer — for quantitative analysis by light absorption.
• Brinkmann Automatic Titrator — for wet chemical assays.
• Tablet Dissolution/Disintegration equipment — to guarantee conformance with rigid USP specifications.

• Physical testing equipment determines tablet weight, hardness, thickness, and friability, as well as tap density and particle size of powders.

• Our complete Microbiology Lab guarantees that raw materials and finished products comply with strict USP requirements.

• Accelerated shelf-stability testing is performed in a range of humidified and non-humidified chambers.
