AutoDesorb® System Development Team


Automated Short Path Thermal Desorption System

The AutoDesorb System was developed using the SIS patented Short Path Thermal Desorption Technology.  This Automated Short Path Thermal Desorption System is the result of 5 years of development at Scientific Instrument Services. During this time, 5 prototypes were designed and manufactured.  In each successive system, new improvements were incorporated to improve the mechanical performance of the system, reduce its weight and size and make it user friendly.  

The AutoDesorb System was first  introduced at PittCon 99 in Orlando, FL in March 1999.  The latest version entitled AutoDesorb Model 2000 will be introduced in September 1999.  This latest model now includes multi step desorption heater block programming, a  LN2 as well as CO2 Cryo-Trap with automatic detection, a prefilter cartridge in the connecting tube to assure clean pure carrier gas for purging samples, a new desorption tube needle design which permits leak-tight sealing of the needles with finger tight connections, and expanded graphics in the system software.  In addition the Model 2000 was designed to also work with the HP 5890 GC, provided the latest version of ChemStation is installed which operates under Windows NT.  The Model 2000 was ready to ship October 1, 1999.  

The following Scientific Instrument Services team members are responsible for the development of the AutoDesorb System.

  • John Miller, Chris Baker, Roland Roadenbaugh, Eric Butrym, David Manura

Project Management

John Manura was responsible for the overall development of the AutoDesorb System, including the coordination of the development team, scheduling and introduction at PittCon 99.

Mechanical System Design

John Manos of SIS was responsible for most of the final design of the AutoDesorb System including the design and refinement of many of the mechanical systems and the final packaging design. Many other members of the staff of SIS also contributed to the mechanical design of the AutoDesorb System including Dan Lieske, John Miller, Chris Baker, and John Manura. The ideas and input from everyone helped develop this system. Vin Das, a graduate student from Rutgers University, worked under contract for SIS to help develop the AutoDesorb System. Vin's project was to take the ideas developed in our first prototype, reduce the size of the system and improve its performance.

Mechanical System Manufacture and Assembly

Dan Lieske was responsible for the manufacture of the system components in the SIS machine shop. From the drawings and ideas of the project team, Dan aided in the design of many of the components and machined all the components for the AutoDesorb System. Dan Lieske, John Manos, John Miller and Roland Roadenbaugh together assembled the components into the final AutoDesorb System.

Electronics System Design and Assembly

John Miller was responsible for the design and assembly of the electronics interface for the AutoDesorb System. This system is used to interface the AutoDesorb System to the PC. John Miller was assisted by Roland Roadenbaugh in designing the electronics boards, assembling the components, wiring the system and debugging the system when finished.

PC Software Design and Development

The PC Software used to run the AutoDesorb System was designed and developed by David Manura.  David wrote the software for the Windows screens, the interface to the HP ChemStation Software and the microprocessor software for the electronics interface. David was assisted by Steve Colby in the initial software systems organization.

Applications Development

Vin Das, Eric Butrym and John Manura are developing applications for the AutoDesorb System. Two of these applications are being presented at PittCon 99 and will appear as application notes on our WEB site. Additional applications including environmental and food science applications are under development.

Advertising and Marketing

John Manura is responsible for the development of the advertising material for the AutoDesorb System, including the SIS WEB site on this product, journal advertising, trade shows and press releases. Chris Baker and Eric Butrym are responsible for the development of the AutoDesorb Manual. Phil Tielmann is our graphic artist responsible for the production of all artwork and advertising media.
