Mass spectrometry provides the highest level of credibility and certainty of any analytical approach. ISURA employs a variety of state-of-the-art spectrometry equipment capable of identifying about 700 known contaminants, including targeted analyses of pesticides, herbicides, fungicides, solvent residues and toxic heavy metals at ultratrace concentration levels.
Furthermore, all ISURA’s laboratories and partner laboratories meet ISO 17025 standards for these specific methods (or are in compliance with ISO 17025 standard).
Here are some of the specialized mass spectrometry tests we conduct:
Headspace Gas Chromatography Mass Spectrometer
This test is used to detect volatile contaminants such as solvents. It is able to detect residual solvents as low as 0.1 ppm (part per million) lower than the specification of USP (United States Pharmacopoeia). Unknown compounds are easily identified by their mass spectral fingerprint through a library created by the NIST (National Institute of Standards and Technology)
Gas Chromatography Triple-quadruple Mass Spectrometer
This test is used to detect semi-volatile, non-polar contaminants including many insecticides, fungicides, and herbicides. This test can detect contaminants at ppb (parts per billion) levels. Contaminants are analyzed in each run including organochlorine, organophosphorous, bridges diphnyl, pyrethroid insecticides; pyrethroid synergists, chlorinated aromatic fungicides and polycyclic aromatic hydrocarbons (PAHs).
Ultra High Performance Liquid Chromatography Triple-quadruple Mass Spectrometer
This test is used to detect polar contaminants including many pesticides and toxins. It is a very selective and sensitive detection tool for water-soluble contaminants at trace levels. It analyzes contaminants including newer classes of pesticides, mycotoxins, plasticizers such as phthalates, and veterinary drugs and antibiotics.
Inductively-Coupled Plasma Mass Spectrometer
This test is used to detect elemental impurities. It screens, identifies, and quantifies trace levels of heavy metal contaminants and high levels of radioactive isotopes. It is 100 times more sensitive than optical ICP technologies. It analyzes samples by parts per billion level to ensure compliance with California’s Prop 65 limits on toxic elements.
Quantitative-Polymerase Chain Reaction(Q-PCR) Real-Time PCR
Real Time PCR is used to detect genetically modified (GMO) or genetically engineered (GE) organisms sequences in products or the raw material. It is the most sensitive and most reliable test method available for GMO screening. It quantifies the amount of genetically modified DNA. It can also detect extremely low GMO concentrations in a wide range of materials even after they have been processed.
