ICP-MS

Our Agilent 7500c ICP-MS (quadrupole) equipped with a collision chamber can be used to analyze environmental samples (water and soil) and biological samples (kidney, liver, urine, etc) for trace elements (V, Cu, Zn, Fe, Mn, Co, Sr, Mg, Ni, Cr, Cd, Mo, As, Se, Mo, Sn, Sb, Pb, U). Depending upon sample concentrations, we can analyze most any element between Li and U (~70). We also have the capability to perform isotopic analysis for Pb (masses 206, 207, and 208).

 

We currently have appropriate digestion methods and have analyzed the following sample types:

 

  • Bird feathers
  • Blood
  • Mosquito Coils
  • Snails
  • Fish
  • Beetles
  • Soil
  • Water
  • Wine
  • Fruit
  • Plants – stems, leaves, roots

 

 We can develop methods for various sample types, so if yours is not listed please feel free to contact us.

 

Services and Fees

For routine sample analysis, see the chart below for sample costs. Note that all costs are negotiable. If you have a large number of samples, costs will decrease.

LC-MS

LC-MS couples the separation power of reverse phased high-performance liquid chromatography (RP-HPLC) with a mass spectrometer (MS).

Our lab houses a Thermo LC/MS/MS, which best detects small (0.1-2 kD) molecules. Our LC/MS/MS services are custom designed for projects that require methods of characterizing molecules in environmental samples. Molecules analyzed may be natural, synthetic, purified, or in complex matrices, and are detectable down to 1 ppb (part per billion). Methods are run on a 50 mm C18 column with customized solvent gradients to provide effective separation of analytes in complex mixtures.

For routine LC-MS analysis, we offer a per-sample flat fee of $25.00 USD.

In order to fall into the routine analysis category:

• Analytes should have a molecular weight between 50-2,000 mass units

• Sample needs to have at least 0.1 mg/ml solubility in H2O, methanol, or acetonitrile

• Analytes must be non-volatile and be air/water stable

For non-routine analyses, contact us to discuss your project and request a quote.

 

GC-MS

Gas Chromatography Mass Spectrometry (GC-MS) is used to analyze and quantitate volatile organic compounds in complex mixtures. GC separates mixtures into individual components with a temperature-controlled column. GC is coupled with MS to obtain mass spectra unique to individual analytes. Mass spectra can be cross-referenced with databases to identify compounds.

Our lab houses several Agilent GC-MS (6890 GC, 5975 MS) instruments and specializes in identifying molecules in complex environmental matrices. Through the use of standards in GC-MS methods, quantitation is possible for volatile compounds found in solids, liquids, and gases.

For routine GC-MS analysis, we offer a per sample flat fee of $25.00 USD.

Routine GC-MS analysis involves:

• Volatilization temperature ranges of 200-300ºC

• Mass detection ranges of 50-600 mass units

• Non-polar analytes (derivatization of polar compounds is available for additional charge)

For non-routine analysis, contact us to discuss your project and request a quote.
