Technical Support

The staff of scientists and technicians at Scientific Instrument Services can provide our customers and potential customers with technical assistance on the use of the Short Path Thermal Desorption System. We have a wide range of experience using the technique for both Thermal Desorption analysis as well as Direct Thermal Extraction of samples. If you need assistance in determining the feasibility of these techniques for your analysis, please feel free to call on us. We would be happy to advise you of the applicability of the Short Path Thermal Desorption System to aid you in your problem solving.

Applications Lab

Our applications lab currently consists of Agilent 5973/6890 GC/MS systems. This equipment is utilized for customer demonstrations of the Short Path Thermal Desorption System. We also analyze samples for our customers and do some of our own research. Much of the research we perform is published in various publications including our newsletter, The Mass Spec Source, and we will be presenting many papers at upcoming meetings including the ASMS, EAS, and PITTCON meetings.

Scientific Instrument Services can now offer contract services for the analysis of your sample via our Short Path Thermal Desorption System.

GC/MS Analysis via Short Path Thermal Desorption System & Other MS Services

Scientific Instrument Services is now making available its laboratory facilities, equipment and trained instrumental staff for the analysis of contract samples.

Our equipment includes the following:

  • Mass Spectrometers: Agilent 5973s with Agilent 6890 GCs.
  • Direct probe including high temperature & DEP probe analysis.
  • Thermal Desorption Systems: S.I.S. Short Path Thermal Desorption Systems with both CO2 and Liquid Nitrogen Cryo Traps.
  • A wide variety of sampling accessories including air sampling devices, purge and trap systems and solid samplers.

Our instrumentation laboratory is mainly geared to the analysis of samples via our Short Path Thermal Desorption System. This includes techniques such as air monitoring, P&T from solid and liquid matrix samples and the direct thermal extraction of solid matrix samples. All customer samples are analyzed via a GC/MS system and complete mass spec analysis of chromatogram peaks including NBS library matching as well as hard copy printout of mass spectrum can be supplied. Quantification of samples can also be done. Prices vary depending on the type of samples, length of chromatographic run and type of analysis required.
