Recent Laboratory Services and Test Methods

  •  HPLC/PDA/MS Instrument.  Testing of natural products and dietary supplements active ingredient purity, impurities and adulterated substances.
  •  GC/MS Methods for Banned Substances.  Testing of products for Federal and State banned substances.
  •  Microorganism Removal Efficiency of Air Cleaners.  We recently conducted testing in our sealed environmental chamber for the removal efficiency of home air cleaners using laboratory prepared microorganism spores.
  •  Siloxanes from Landfill Gases by GC/MS Using Sorbents.  Landfill gases can contain Siloxanes and form silicon dioxide in combustion engines used to convert methane to energy.  Sampling using a sorbet tube collects the Siloxanes and the GC/MS analysis of the samples can detect 8 different Siloxanes.  Using a 20 liter air sample, detection limits are 5-10 ppbv.
  •  Microbial Volatile Organic Compounds in Indoor Air by GC/MS Ion Trap.  Air samples can now be collected in Summa canisters or on sorbent tubes, then analyzed in full scan and Selective Ion Storage modes during the same run.  Picogram levels of selected MVOCs and the ability to perform NIST/EPA Mass Spectral Library Searches for unknown compound identifications with one analysis makes this test method the most comprehensive available.  
  •  Ion Trap MS technology detects parts per trillion levels for TO-14A/TO15 target compounds for risk assessment and odor testing in air and water.  Hazardous air pollutants and odor causing chemicals can now be detected at levels not previously obtainable with traditional quadrapole MS with full scan analysis.  New water headspace testing methods can identify odors caused by algae growth.
  •  Pesticide Residues Sampling & Analysis by GC/ECD; GC/TSD; GC/MS.  Samples of air, soil, vegetation, and water are collected in homes, workplaces, streams, and farm runoff locations to determine environmental impact and human exposures.  This service supports governmental monitoring programs, litigation activities, and dietary supplement testing of medicinal herbs.  Purity assay and impurity identifications for EPA pesticide registration submittals.
  •  Polarimeter for measuring Specific Rotation of pure compounds.
  •  FT-IR for pure and finished products.  Spectral database of 16,000 organic compounds.

 Study Reveals Biological Clock in Plants.

Raleigh, NC, July 11, 2011:  Scientists at Research Triangle Park Laboratories have discovered that plants have a built-in energy-transfer mechanism that could represent a potential biological clock.  According to Roy T. Gorman, principal scientist, this energy-transfer mechanism or biological clock operates under both light and dark conditions, which indicates that the circadian rhythm they observed occurs independently of light or photosynthesis.  “The implications of these findings could extend to all organisms,” said Gorman.  “And the fact that this energy-transfer mechanism or biological clock isn’t dependent on light or chemicals opens up many new areas for research that might help explain how organisms harvest energy.”

 RTP Labs recorded changes in pH, a measure of acidity or alkalinity, in water-culture tanks in which Chrysanthemums were grown.  Their surprising results demonstrated an increase in pH (greater than pH 7) when the water temperature decreased and a decrease in pH (less than pH 7) when the water temperature increased.  “Low levels of pH (<3) were attributed to acid released from the root mass of the plants,” Gorman explains “But the high levels of pH (>9) appear to result from the splitting or dissociation of water molecules into various forms of elemental hydrogen and hydrogen plus oxygen.”

 Hydrogen has long been recognized as a potential source of clean energy that may one day supplement our dwindling supplies of hydrocarbon fuels.  An abundant source of hydrogen can be found in water, simply H2O, but finding an economical means of separating hydrogen from water remains an elusive goal. Many studies have attempted to identify an inexpensive method for splitting the water molecule, but so far all have required more energy than can be gained from this process.  Results of the RTP Labs study strongly suggest that water will dissociate naturally.  Harvesting hydrogen from this naturally dissociated water may be far more economical than splitting water to obtain hydrogen.  Further studies in this area may reveal a potential new and economical source of energy as well as a means of providing clean water for human consumption.  This study was recently published in the WATER, and is available online at  Further information is available from Research Triangle Park Laboratories, Inc.
