    Scientific Instrument Services on the World Wide Web Scientific Instrument Services introduced its WEB site in September 1995. Since that time the usage of the information our our site has continued to grow as more chemists and technicians gain access to the WEB and the resources that are found here. The initial goal of our WEB site was to make information available to our customer base. This includes the Application Notes that we have written on Mass Spectrometers and Thermal Desorption Systems...

Chemical Reaction Interface Mass Spectrometry (CRIMS)

Scientific Instrument Services is currently developing both GC and LC CRIMS systems. These products are based on the work and methods of Fred Abramson of George Washington University. The GC CRIMS system has been built and is currently being tested in our laboratory. The GC-CRIMS systems will be introduced at the EAS meeting in Sommerset, NJ in November and will available for delivery this fall. Over the next few months we will be assembling an LC-CRIMS system which will be introduced at Pitt Con in March 1998 and is scheduled for shipment in late Summer 1998. These systems will be available as full GCMS or LCMS Systems based on the new HP 5973 MSD.

For additional information please contact Scientific Instrument Services at (908) 788-5550.

Building Expansion at Scientific Instrument Services

Scientific Instrument Services has begun construction of new shop and repair facilities at our Ringoes, NJ location. This expansion has been in the planning stages for more than three years. The new addition more than doubles our facitities to about 10,000 square feet of offices, shops and warehouse. The major purpose of this addition is provide us with new and expanded shop facilities to better serve our customers. Included in the new expansion are two filament repair rooms, a sandblasting room, a filament assembly and cleaning room, a welding and brazing room, an equipment assembly room, a quality control room, a product development room, a drafting and computer room, offices for our shop and product development staff and a lunch and lecture room. In addition we are constructing a machine shop in the basement of the new addition. Construction is expected to be completed by mid September. This expansion will enable us to expand our staff as well as add additional equipment and repair capabilities. The old shop areas in the present building will be remodeled into new offices for our office staff.

SIS Web Site - Catalog Pages Indexed

The catalog product section of the SIS web pages are now indexed. This makes it easy to retrieve pages of our catalog using an expanding and contracting index system in the left frame of the page. The index starts with the 11 major sections of our catalog (i.e. MS, GC, LC, etc.) and then expands by two more layers when the sections are selected. Selecting an already expanded section, returns the index back to its original size. In addition the Search function of this section can be used to quickly search our entire web site for products of other items of interest.

This is part of an expansive revision of our catalog web pages. In this revision we are including on-line ordering, via either your corporate account number or credit card. We also have these WEB catalog pages interfaced to the SIS computer inventory system to permit the automatic update of product prices so that our system will always be up to date. In addition the ordering section will automatically calculate the shipping charges for your order via the shipping carrier of your choice. These pages are being created and designed by David Manura (SIS Webmaster). The programs are written in four computer languages (HTML, Pearl Scripts, C++ and Javascript). You will notice part of the online ordering as part of many of the present pages (vacuum section), however, we will not put the actual on line ordering form in place until the mass spec and thermal desorption WEB page sections are complete. This will probably occur in August 1997.

Note: you must have Javascript capabilities on your browser in order to use this on line ordering system.

Direct Probe and Probe Inlet System for the HP 5973 MSD

Complete Probe Inlet System and Controller

S.I.S. has developed a new direct probe and probe inlet system for the Hewlett Packard 5973 MSD. The probe inlet mounts onto the GC/MS transfer line port and uses an indexed probe introduction guide to permit the direct insertion and removal of the probe into the MSD source without venting the MSD or scoring the probe rod. The probe can be either heated ballistically or at ramp rates in excess of 500 degrees per minute or can be temperature programmed with up to 25 ramp rate levels. The probe temperatures, ramp rates, hold times, start and stop are all PC controlled and fully integrated with the HP ChemStation software. This permits the storage of the probe analysis parameters in the sample data files and the method files. Shipping of the new probe inlet system is scheduled for Jan 15, 1997.

SIMION 3D Courses at PittCon 97 (link gone)

S.I.S. will be offering two day courses on the use and application of the SIMION 3D ion Optics Simulation Software at PittCon 97. These two day courses will enable the person attending to become totally familiar with the basic use of SIMION 3D ion optics simulations software and demonstrate its application to the solving of ion optics problems. This class will be similar to the course presented at ASMS 96 by David Dahl. It will consist of lectures interspaced with hands-on practice on a personal computer (2 persons per PC). In this course you will learn the fundamentals of SIMION and become capable of utilizing advanced techniques in solving specific analytical problems. Material will be covered at both the elementary and advanced level. The course is designed to dramatically accelerate the learning curve for effective use of the program. Numerous tips and techniques will be presented for users at all levels. More information or to register On-Line.

NEW SIMION 3D Ion Optics Modeling Software from SIS

SIS is your dealer for SIMION 3D Ion Optics Modeling Software. For detailed information on SIMION see the SIMION Section. Simion is now available at a special introductory price of only $495.00

View the new Application Notes now on line which demonstrate the application of SIMION 3D. These two application notes demonstrate some of the uses that the staff of SIS are using in order to study mass spectrometer source and filament design.

  • Application Note 45 - Application of SIMION 6.0 to Filament Design for Mass Spectrometer Ionization Sources
  • Application Note 47 - The Application of SIMION 6.0 to Problems in Time-of-Flight Mass Spectrometry
Simion 3D version 6.0 is a new PC based ion optics simulation program designed for modeling ions mass spectrometers and other ion optic instruments. At SIS we use this program to design new mass spectrometer filaments and to study mass spec source design. Manufacturers of electron multipliers use this software to design their detectors and instrument designers use it to design new instruments and to maximize the sensitivity of the instruments. Use this powerful software to study ion source and detector optics in time-of-flight, quadrupole, ion trap and magnetic sector mass spectrometers in order to discover improvements that can be made to your instruments as well as to develop new instrument designs.

Steve Colby is responsible for the addition of this new product to SIS and can answer your technical questions on SIMION. Steve plans several posters for presentation at ASMS and will be there to answer your questions. You can reach Steve at (908) 788-5550 or via e-mail.
