Hyperlink to any of the above titles to view an abstract on the above posters. One particular paper of importance to the mass spectrometer user is the poster presentation on Thursday by Sandy on Pump Oils for vacuum pumps. For this paper we ran 2 vacuum pumps with 2 different oils (Inland 19 & Invoil 45) for three months. Oil samples were removed every week and analyzed via purge and trap GC/MS. The two pump oils were then compared to demonstrate the degradation of these oils and to show why pump oils should be changed frequently. Steven Colby will also be presenting several posters to demonstrate the use of the SIMION 3D software in the design of mass spectrometer sources (Monday) and in Time-of-Flight Mass Spectrometers (Thursday). Additional applications of Simion can also be discussed with Steve at our hospitality suite.

NEW Edwards Vacuum Pumps Now Available from SIS

SIS has just acquired a dealership for the Edwards line of Vacuum pumps and Diffusion pumps. We have had many requests from our customers to carry the Edward vacuum rough pumps as replacements for their mass spectrometers. Many manufacturers such as Hewlett Packard use the Edwards pumps in their new mass spectrometers. In addition many users prefer the Edwards pumps because they are much quieter than other direct drive rough pumps on the market. We have carried the Alcatel line of pumps for many years and will continue to carry both the Alcatel and Edwards lines of Vacuum Pumps and accessories. Give us a call with your requirements.

NEW Micro Cryo-Trap to be Introduced at Pitt Con by SIS

SIS has developed a new 1.0" long GC Cryo-Trap for trapping volatiles at the front of a GC column. This new product will be introduced at PittCon in March. We have conducted studies that have shown that the trapping region in the GC Cryo-Trap can be 1.0 inch or less in length. The new Micro GC Cryo-Trap uses less than 3% of the cooling gas that would be required to cool the entire GC oven and less than 1/4 the cooling gas used to cryo-trap via other trapping devices on the market. The result is more efficient trapping of volatiles at temperatures down to -70 degrees C using liquid CO2 and down to -180 degrees C using liquid nitrogen. In addition the trap can be heated up to 400 degrees C at a ballistic ramp rate of about 1000 degrees per minute to rapidly and efficiently release the volatile organics. Additional details are listed on the Micro Cryo-Trap pages and Application Note 38 fully describes this product.

NEW SIMION 3D Ion Optics Modeling Software from SIS

SIS is now 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

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
